There was a problem that it was difficult to understand changes in temperature and humidity over time.

It is an object of the present invention to provide a temperature and humidity measuring device that can easily determine whether the measured value of a temperature and humidity measuring device is a comfortable or uncomfortable state, and that can also detect changes in temperature and humidity over time. Our objective is to provide a humidity measuring device.

A control section calculates the position of a temperature/humidity measurement point on the graph display screen from the humidity value, and outputs a display signal indicating the temperature/humidity measurement point to the display section.

The A/D converter 3 receives the analog signals output from the temperature sensor 1 and the humidity sensor 2, converts the analog signals into digital signals, and outputs the digital signals.

On the other hand, as shown in FIG. receiving a display signal indicating a temperature/humidity measurement point 12 that is the intersection of the temperature value and the humidity value measured by the humidity sensor 2;
It is configured to display temperature and humidity measurement points 12 on the graph display screen. The range indicated by diagonal lines on the graph in FIG. Depending on whether or not there is a measurement point that is the intersection of the measured humidity values on the vertical axis 11, it can be easily determined whether the condition is comfortable or uncomfortable.

The control unit 4 determines the temperature and humidity measurement point 1 on the graph display screen of the display unit 6 based on the temperature value and humidity value expressed by the measured digital signal output from the A/D converter 3.
