1. Technical Field
The present disclosure relates to an apparatus and method for measuring temperature and humidity.
2. Description of Related Art
A conventional method for measuring temperature and humidity of environment is by using a thermometer or a hygrometer. The temperature value and the humidity value are manually recorded by an operator. Recording of the temperature and the humidity values may be laborious and time consuming.
Therefore, there is a need for improvement in the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
The detecting unit 100 determines a temperature reading and a humidity reading, and outputs analog signals according to the temperature reading and the humidity reading. The A/D converting unit 200 receives the analog signals, and converts the analog signals to digital signals. The processing unit 300 receives the digital signals, and compares the digital signals with the reference temperature values and the reference humidity values to determine whether the digital signals are valid. The processing unit 300 determines the digital signals are valid when the digital signals are within a range of the reference temperature values and within a range of the reference humidity values. The processing unit 300 converts the digital signals which are valid to temperature values and humidity values. The storage unit 400 receives and stores the temperature values and the humidity values. The processing unit 300 generates a waveform of temperature and a waveform of humidity according to the temperature values and the humidity values. The waveform of temperature and the waveform of humidity are stored in the storage unit 400. The display unit 500 receives and displays the temperature values, the humidity values, the waveform of temperature and the waveform of humidity.
In one embodiment, the storage unit 400 includes a Universal Serial Bus (USB) port 410. The storage unit 400 is configured to communicate with a computer 420 via the USB port 410. The storage unit 400 is configured to transmit the temperature values, the humidity values, the waveform of temperature and the waveform of humidity to the computer 420 via the USB port 410.
S201: the detecting unit 100 determines a temperature reading and a humidity reading, and outputs analog signals according to the temperature reading and humidity reading;
S202: the A/D converting unit 200 receives the analog signals, and converts the analog signals to digital signals;
S203: the processing unit 300 receives the digital signals, and compares the digital signals with the reference temperature values and the reference humidity values to determine whether the digital signals are valid; if the digital signals are not within the range of the reference temperature values and not within the range of the reference humidity values, returns to step S201; if the digital signals are within the range of the reference temperature values and within the range of the reference humidity values, the digital signals are valid, the procedure goes to step S204;
S204: the processing unit 300 converts the digital signals which are valid to temperature values and humidity values;
S205: the storage unit 400 receives and stores the temperature values and the humidity values;
S206: the processing unit 300 generates a waveform of temperature and a waveform of humidity according to the temperature values and the humidity values;
S207: the display unit 500 receives and displays the temperature values, the humidity values, the waveform of temperature and the waveform of humidity;
S208: the storage unit 400 transmits the temperature values, the humidity values, the waveform of temperature and the waveform of humidity to the computer 420 via the USB port 410.
Even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and the arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
