The proximity sensor 123 may be an infrared Sensor and is capable of detecting approach of a specific object to the sensing device 10, change of distance between the products or door to which the sensing device 10 is installed and surrounding structures, or the like.

The first unit 101 may further include a battery 150. The battery 150 may be a secondary battery which is capable of charging and discharging. The first unit 101 may further include a charging circuit for charging, but it is limited to this.

Here, so that the usage time of the battery 150 may be maximized, the processor 132 may be activated when vibration over a specific value is detected at the acceleration sensor 121, in a state where the processor 132 is deactivated.

When the processor 132 is activated, the processor 132 compares information detected at least one of the acceleration sensor 121, the temperature and humidity sensor 122, and the proximity sensor 123 to reference information stored in the memory 134 with each other.

The first unit 101 may further include a connector 160 for inputting power for charging of the battery 150.

Accordingly, when a portion in which the pressing projection 112 is provided in the transmitting portion 110 is pressed by a user, the pairing button 126 may be selected by the pressing projection 112 pressing the pairing button 126.

The first unit 101 may further include a reset button 180. A function which is to perform by the sensing device 10 is stored in the memory 134. When the reset button 180 is selected, the information regarding to a predetermined function may be deleted from the memory 134 and then a new function may be selected by the mobile device 50.

In addition, the information (detected information) detected by the sensing device 10 is stored in the memory 134 while the selected function is performed by the sensing device 10. When the reset button 180 is selected, the detected information stored in the memory 134 may be deleted while the function of the sensing device 10 is maintained as the selected function.

The pairing process between the sensing device 10 and the mobile device 50 as an example of the external device will be simply described.

The mobile device 50 is capable of executing an application for using the sensing device 10 in order to performing the pairing the sensing device 10 and the mobile device 50 with each other and a user may select the pairing button 126 of the sensing device 10.

When the pairing button 126 is selected, the sensing device 10 is capable of sending inherent information of the sensing device 10 to the mobile device 50 and thus the mobile device 50 is capable of acquiring the information of the sensing device 10.

A list of the searched sensing devices 10 may be displayed on the display portion of the mobile device 50 and thus a specific sensing device 10 may be selected on the list.

A screen for setting a function of the selected sensing devices 10 may be displayed on the display portion of the mobile device 50 and thus the function of the sensing device 10 is set on the screen.

When the function of the sensing device 10 is set, a screen for selecting a household appliance to be interacted with the sensing device 10 may be displayed on the display portion of the mobile device 50. For example, in a case where the sensing device 10 is selected as a washing apparatus sensor, a household appliance to which the sensing device 10 is attached is selected on the display portion. At this time, the household appliance to which the sensing device 10 is to be attached may be registered to the server 60 through the mobile device 50 in advance.

When the function of the sensing device 10 is selected in the mobile device 50, guide information for guiding a position to which the sensing device 10 is to be attached per a selected household appliance or per a selected function may be displayed on the display portion of the mobile device 50.

When the refrigerator is selected as a household appliance, a guide message or a screen which guides to attach the sensing device 10 to one door of the refrigerator washing apparatus may be displayed.

When the robot cleaner is selected as a household appliance, a guide message or a screen which guides to attach the sensing device 10 to a position adjacent to an infrared receiver in the robot cleaner may be displayed on the display portion.

When the selected function is a door opening detecting function, a guide massage or a screen which guide an arrangement relationship between a reflector for reflecting light or a door frame/a window frame and a sensing device may be displayed on the display portion.

In addition, a function of the sensing device 10 in the mobile device 50 is selected, a guide message or a screen for requesting a test to a user in order to confirm whether or not an attaching position of the sensing device 10 is correct may be displayed on the display portion of the mobile device 50.

As an example, a guide message such as “Please, move the door to which the sensing device 10 is attached” may be displayed on the display portion.

In a case where a user moves the door to which the sensing device 10 is attached, movement of the door is capable of detecting at the acceleration sensor 121 of the sensing device 10 and then the information detected at the acceleration sensor 121 may be acquired by the mobile device 50.

In a case where the mobile device 50 acquires the information detected at the acceleration sensor 121, a screen for confirming the selected function may be displayed on the display portion of the mobile device 50.

The user confirms a function of the sensing device 10, the set function is sent to the sensing device 10 and then is stored in the memory 134 of the sensing device 10. Then, the sensing device 10 is capable to performing the set function.

Hereinafter, various functions of the sensing device 10 will be described.

FIG. 6 is a view illustrating a state where the sensing device is attached to the washing device, FIG. 7 is a view illustrating a first screen displayed at a mobile device, and FIG. 8 is a flow chart illustrating an operating algorithm of the sensing device when the sensing device is attached to the washing apparatus and used.

First, with reference to FIG. 6 and FIG. 7, a function of the sensing device 10 is capable of being selected in a pairing process between the sensing device 10 and the mobile device 50.

The sensing device 10 is capable of performing a function related to the washing apparatus 22 as an example.

The sensing device 10 may be attached to a door 22a of the washing device 22, but it is not limited to this.

A user is capable of selecting a function of the sensing device 10 and inputting a name of the function on a first screen 510 displayed on the mobile device 50.

In addition, a selection portion 512 for selecting where or not a push notification function is used may be displayed on the first screen 510.

When the push notification function is selected, multiple types of notification functions may be individually selected at the first screen 510. As an example, a first selection portion 513 for selecting a first notification function for inducing laundry collection after completion of washing of the washing apparatus 22.

The first notification function may be a function which is performed immediately after a washing completion of the washing apparatus 22 may be displayed on the first screen 510.

A second selection portion 514 for selecting a second notification function for once again inducing laundry collection after performing the first notification function may be further displayed on the first screen 510.

At least one time selection portions 515 and 516 for selecting time which generates notification may be further displayed on the first screen 510.

In other words, waiting time from the time point when the first notification function is performed to the time point when the second notification function is performed may be selected.

When a usage target and a function of the sensing device is selected in the mobile device 50, the sensing device 10 receives a selected function from the mobile device 50 and then performs corresponding function to the selected function.

With reference to FIG. 8, the sensing device 10 waits as a washing apparatus sensor in a state where the sensing device 10 is attached to the washing apparatus 22 (S1).

The processor 132 is in a deactivated state in a state where the sensing device 10 is in a waiting state.

It may be determined whether or not vibration having value equal to or more than a predetermined value is detected in the acceleration sensor 121, in a state where the sensing device 10 is in a waiting state (S2).

The vibration value detected at the acceleration sensor 121 is greater than activation reference vibration value, in a case where a user allows the door 22a of the washing apparatus 22 to be opened in order to use the washing apparatus 22.

Accordingly, the acceleration sensor 121 activates the processor 132, in a case where vibration value detected at the acceleration sensor 121 is larger than the activation reference vibration value.

The processor 132 is capable of determining whether or not washing start is detected after the processor 132 is activated (S3). As an example, the processor 132 is capable of determining whether or not the vibration is detected until reference time lapses after the processor 132 is activated. In addition, the processor 132 is capable of determining whether or not a vibration pattern determined at the acceleration sensor 21 is the same as a reference pattern.

The processor 132 is capable of repeating an active state and a sleep state at a constant period after the processor 132 is activated.

For example, in a state where the processor 132 is activated, the processor 132 may be in the active state during a first reference time and may be in the sleep state during a second reference time. This state change may be repeatedly performed.

As a determination result in a step S3, after the processor 132 is activated, when it is determined that the washing start is not detected, the processor 132 may be again converted into a deactivated state. In other words, the sensing device 10 may be in the waiting state again.

On the other hand, as a determination result in a step S3, after the processor 132 is activated, when it is determined that the washing start is detected, the processor 132 is capable of determining whether or not spin-drying is completed (S4). In general, the washing apparatus 22 is capable of performing a washing process, a rinsing process, and a spin-drying process, and the washing course may be ended when the spin-drying is completed.

Accordingly, the processor 132 is capable of determining whether or not the spin-drying is completed in order to determine a completion of the washing course (S4).

In the present specification, conversion period between the active state and the sleep state of the processor 132 in the washing process is the same as or different from the conversion period between the active state and the sleep state of the processor 132 in the spin-drying process.

For example, in the spin-drying process, the processor 132 is in the active state during a third reference time and is in the sleep state during a fourth reference time and this state change may be repeatedly performed.

At this time, the third reference time is the same as or different from the first reference time and the fourth reference time is the same as or different from the second reference time. The length of the third reference time may be less than the length of the first reference time. The length of the fourth reference time may be greater than the length of the second reference time in a case where the third reference time is different from the first reference time.

A sum of the first reference time and the second reference time is the same as or different from a sum of the third reference time and the fourth reference time. The sum of the first reference time and the second reference time may be greater than the sum of the third reference time and the second reference time in a case where the sum of the first reference time and the second reference time is different from sum of the third reference time and the fourth reference time.

The processor 132 is capable of determining the washing process and the spin-drying process in a distinguished state from each other, based on the vibration detected from the acceleration sensor 21.

As a determination result in a step S4, when it is determined that the spin-drying is completed, the processor 132 may determine whether or not the vibration is detected before the reference time lapses (S4).

According to the washing course, the spin-drying process is performed multiple times and the spin-drying may be performed in the washing process. In this case, it is firstly determined that the spin-drying is ended by detecting the spin-drying process. However, actually, the vibration may be detected before the reference time lapses since the rinsing and washing is proceeded again.

Accordingly, Step S5 may be a step for determining that the washing is substantially ended.

As a determination result in a step S5, when it is determined that the vibration is detected before reference time lapses, it is capable of determining whether or not the opening of the door is detected (S6).

As a determination result in a step S6, when it is determined that he door opening is detected, the processor returns to the step S1. In other words, the processor 132 is converted into the waiting state and then in a deactivated state.

On the other hand, as a determination result in a step S6, the processor 132 determines that the washing is ended. Therefore, the sensing device 10 is capable of sending the washing completion notification information to the mobile device 50. Subsequently, the processor 132 is converted into the door opening waiting state.

The processor 132 is capable of determining whether or not the door opening is detected before the notification reference time lapses (S8).

As a determination result in a step S8, when it is determined that the door opening is not detected before the notification reference time lapses, that is, when it is determined that the door 22a is not opened until predetermined time lapses after the washing is ended in the washing apparatus 22, the sensing device 20 sends information for collection notification to the mobile device 50 (S9). At this time, information for the laundry collection notification may be displayed in the display portion of the mobile device 50.

According to the present embodiment, the sensing device 10 is capable of determining whether or not the washing in the washing apparatus 22 is ended and the door 22a is opened by the sensing device 10 being attached to the washing device even if the washing device does not include a communication module, and the sensing device 10 is capable of sending the information for the washing completion notification and the information for the laundry collection notification to the mobile device. Accordingly, convenience of a user may be improved, since the user is capable of confirming notification information for the laundry collection at the display portion of the mobile device 50.

Further, consumption of the battery 150 may be minimized and thus available period of the battery 150 may be increased since the processor 132 is in a wait state as a deactivated state and then is converted into the activated state by the detection information of the acceleration sensor 121.

FIG. 9 is a view illustrating a state where the sensing device is attached to a refrigerator, and FIG. 10 is a view illustrating a second screen displayed at a mobile device.

With reference to FIG. 9 and FIG. 10, the sensing device 10 is capable of performing a function related to a refrigerator 21 as an example.

The sensing device 10 may be attached to a door 21a of the refrigerator 21, but it is not limited to this.

A user is capable of selecting a function of the sensing device 10 and inputting a name of function on a second screen 520 displayed on the mobile device 50.

In addition, a selection portion 521 for selecting where or not a push notification function is used may be displayed on the second screen 520.

When the push notification function is selected, multiple types of notification functions may be individually selected at the first screen 510.

As an example, a first selection portion 522 for selecting a function for managing a storage period of food stored in the refrigerator 21 may be displayed in the second screen 520.

In addition, a food selection portion 526 for selecting a name of a food to be managed by being stored in the refrigerator 21 in the second screen 520 may be displayed on the second screen 520.

A second selection portion 523 for selecting function (referring to as a refrigerator unused-state notification function) for confirming and notifying that the door 21a does not open during a long period of time may be displayed in the second screen 520.

In addition, a period selection portion 524 which is capable of selecting reference period for performing a refrigerator unused-state notification function and a phone number selection portion 525 for selecting a phone number for sending push information when a long time unopened-state of a door is detected may be displayed in the second screen 520.

When a usage target and a function of the sensing device 10 are selected in the mobile device 50, the sensing device 10 receives a selected function from the mobile device 50 and then performs corresponding function to the selected function.

When the refrigerator unused-state notification function is selected in the mobile device 50, the sensing device 10 may be operated in order to performing the selected refrigerator unused-state notification function.

The sensing device 10 may detect whether or not the door 21a of the refrigerator 21 is opened or closed.

At this time, the processor 132 may be converted into the activated state based on the vibration detected at the acceleration sensor 121 while the processor 132 waits in a deactivated state as when the sensing device 10 is used in a state of attaching to the washing device.
