Further, the device 100 may include an indicator 104 suitable to indicate a level of the concentration of the gas detected by the gas sensor in the vicinity of the device 100. In the illustrated embodiment, the indicator 104 is shown as LED display 140 to visually indicate the level of carbon monoxide in the surrounding of the device 100. In the illustrated embodiment, the LED display 140 is a multi-color LED display configured to display lights of distinct colors depending upon the level of concentration the gas, for example, the carbon monoxide, in the surrounding of the device 100. For example, the LED display 140 is configured to display a light of a first color, for example, blue color, when the level of concentration of the gas in the surrounding of the device 100 is below a first threshold value. The first threshold value may correspond to a safest value. Additionally, the LED display 140 is configured to display lights of distinct colors, for example, green, yellow, orange, and red depending on the levels of the concentration of the gas lying above the first threshold value. For example, the LED display 140 may display a light of a second color, for example, a green color, when the level of the concentration of the gas in the surrounding area is between the first threshold value and a second threshold value. Similarly, the LED display 140 may a display a light of a third color, for example, a yellow light, when the level of the concentration of the gas in the surrounding area is between the second threshold value and a third threshold value. Moreover, the LED display 140 may display a light of a fourth color, for example, an orange light, when the level of the concentration of the gas in the surrounding area is between the third threshold value and a fourth threshold value. Further, the LED display 140 is configured to display a light of a fifth color, for example, red color, when the level of concentration of the gas in the surrounding of the device 100 is above the fourth threshold value. The fourth threshold value may correspond to a most dangerous level of the gas in the surrounding area. It may be appreciated that the second threshold value is greater than the first threshold value, but less than the third threshold. Similarly, the third threshold value is less than the fourth threshold value, but greater than the second threshold value. Although, the LED display 140 display 5 different lights, it may be appreciated that the LED display 140 may be configured to display any number of lights depending upon the level of the concentration of the gas detected by the gas sensor 102. For example, in some embodiments, the LED display may include only the red light. In such a case, the light is not illuminated when the concentration of the gas in the vicinity of the system is below an associated threshold value.
Although the indicator 104 is contemplated as a visual indicator, it may be appreciated that the indicator 104 may be an audio indicator. In such a case, the indicator 104 is actuated and emit a sound when the concentration of the gas, detected by the gas sensor 102, is above a threshold value. Similarly, the indicator 104 may provide vibrator, and generates vibrations when the detected concentration of the gas is above a threshold value, providing a vibrotactile feedback to the person.
To power the indicator 104, the gas sensor 102, the temperature sensor 221, and other electrical and electronic components of the device 100, the device 100 may include at least one battery 210 arranged inside the housing 110.

In a case where the battery 210 is non-rechargeable battery, the battery 210 may be easily replaced with a new battery upon discharge of the battery 210. Further, to facilitate a charging of the battery 210, the device 100 may include at least one charging socket, for example, a first charging socket 120 of USB-C type and a second charging socket 121 of USB-A type, that enables the charging of the at least one battery 210 from an external power source via a suitable charging cable. Although two charging sockets 120, 121 are contemplated, it may be appreciated that the device 100 may include a single charging socket or more than two charging sockets.
Further, the device 100 includes a switch 141 that is ON-OFF switch to facilitate turning on and turning off of the device 100. As shown, the switch 141 is connected to the housing 110 and extends outwardly of the housing 110, and may be positioned proximate to an edge of the housing 110. In an embodiment, the user may press the switch 141 to turn on and turn off the device 100. When the switch 141 is turned on, the electric power from the battery 210 is supplied to the electrical components of the device 100 to enable a working of the device 100 and measure the level of the concentration of the gas in the surrounding of the device 100. While the electric power to the electrical components of the device 100 from the battery 210 is interrupted when the switch 141 is turned off, stopping the working of the device 100. Moreover, the device 100 may include a wireless charging coil 230 arranged inside the housing 130 and disposed in electrical communication with the battery 210 to enable a wireless charging of an external device, for example, a smart phone of the person carrying the device 100. In an embodiment, to enable the wireless charging of the external device, the external device may be positioned on a surface 130 of the housing 110.
Further, the device 100 may include at least one charging connectors, for example, a first charging connector 122 of USB-C type and a second charging connector 123 of USB-A type, electrically coupled to the battery 210 and configured to facilitate a charging of an external device, for example, a mobile phone. In an embodiment, the charging connectors 122, 123 may be charging sockets extending inside the housing 110 from an outer surface of the housing 110. In an embodiment, the charging connectors 122, 123 may extend outside the housing 110 and may be inserted inside a charging port of the mobile phone to enable the charging of the mobile phone. Although two charging connectors 122, 123 are contemplated, it may be appreciated that the device 100 may include a single charging connector or more than two charging connectors.
Additionally, the device 100 includes a transceiver 220, arranged at least partially inside the housing 110, to enable a communication and exchange of data between the device 100 and an external device, for example, a mobile phone of a technician, in case the device 100 is detached from the mobile phone. The mobile phone is also equipped with an application to further relay information to a remote location such as a central station. The transceiver 220 may be a short-range communication unit, for example, a Bluetooth™ transceiver.
Further, the device 100 includes a controller 223 arranged in communication with the gas sensor 102, the temperature sensor 221, the battery 210, the transceiver 220, the switch 141, the indicator 104, and other electrical and electronic components of the device 100, and is adapted to receive the data from the sensors 102, 221. In an embodiment, the controller 223 receives data about a presence and concentration of the gas in the vicinity of the device 100, and determines the concentration of the gas based on the data. Further, the controller 223 is configured to compare the detected level of concentration of the gas with one or more threshold values, and actuates the indicator 104 based on the comparison. For example, the controller 223 may actuate the LED (light emitting diode) display 140 such that the display 140 shows the blue light if the level of concentration of gas determined by the controller 223 is below the first threshold value. Similarly, the controller 223 may actuate the LED display 140 such that the display 140 shows green light, yellow light, orange light, or the red light depending on the level of the concentration of the gas determined by the controller 223.
In an embodiment, the controller 223 is configured to record/store a date and time stamp when the detected concentration of the gas is above a certain threshold value, for example, the fourth threshold value, or above the third threshold value. Also, the controller 223 may store the value of the concentration of the gas when the detected concentration of the gas is above fourth threshold value or the third threshold value.
In an embodiment, the controller 223 may monitor and store the location coordinates of the device 100 in real time. In an embodiment, the controller 223 may store the location coordinates of the location where the level of concentration of the gas is above the first threshold value, and also stores the associated value of the concentration of the gas. In an embodiment, the device 100 may include a display that may indicate a remaining capacity of the battery 210. Also, the controller 223 is in communication with the mobile device the person or the central station via the transceiver 220 and share all the data monitored and collected by the controller 223 to the mobile device or the central station.
The controller 223 may include a processor 224 for executing specified instructions, which controls and monitors various functions associated with device 100. The processor 224 may be operatively connected to a memory 226 for storing instructions related to the functioning of the device 100. The memory 226 as illustrated is integrated into the controller 223, but those skilled in the art will understand that the memory 226 may be separate from the controller 223 but onboard the device 100, and/or remote from the controller 223 and the device 100, while still being associated with and accessible by the controller 223 to store information in and retrieve information from the memory 226 as necessary during the operation of device. Although the processor 224 is shown, it is also possible and contemplated to use other electronic components such as a microcontroller, an application specific integrated circuit (ASIC) chip, or any other integrated circuit device. Moreover, the controller 223 may refer collectively to multiple control and processing devices across which the functionality of the device 100 may be distributed. For example, the indicator 104, the transceiver 220, the gas sensor 102, the temperature sensor 221, may each have one or more controllers that communicate with the controller 223.
