Come with screw mounting hole.

Power indicator LED.

On board comparator for digital output.

DO will be low when humidity reaches certain level, by adjusting on board potentiometer, the level can be adjusted.

Humidity is higher than the threshold, DO will be LOW.

Turning the on board potentiometer clockwise set the humidity level lower.

AO will output analog voltage.

Operating Humidity range: 20-95%RH

Operating Temperature: 0 -60 degree Celsius

Accuracy: +-5%RH

Onboard pull up with 10K resistor to VCC. High humidity results in lower voltage at A0
