HR202 Humidity Detection Sensor Module

Using high-quality HR202 humidity sensor. The comparator output signal is clean, good waveform, driving ability, more than 15mA The humidity sensor module is sensitive to environmental humidity, generally used to detect ambient humidity by adjusting the potentiometer, for detecting the humidity can change the threshold ( i.e. the humidity control), such as the need to control the ambient humidity of 60% ,then the corresponding module is transferred to the green light and humidity environment , DO high power output when flat, humidity values below this setting, high output, the green light does not shine DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the humidity changes in the environment.
