The HR202 humidity sensor module is sensitive to environmental humidity. It is commonly used to detect ambient humidity by adjusting the potentiometer. The module can change the threshold for humidity control. For instance, if the desired ambient humidity is 60%, the corresponding module will indicate the green light in a humid environment. The DO output can be directly connected to a microcontroller for humidity detection. The relay module’s DO output can drive related equipment to work in the correct environment. The small plates AO analog output modules can be connected to an AD converter for more accurate numerical ambient humidity readings. With 3mm screw holes, the module is easily fixed for installation.

The comparator output signal is clean with a good waveform and a driving ability of more than 15mA. The LM393 chip ensures stable work. The DO small digital outputs interface provides a clear indication with 0 and 1 outputs. The trigger level is adjustable from preset, with LEDs indicating output and power.
