More info

The HR202 Humidity Sensor Module  can be applied to the storage compartment, indoor air quality control, building automation, medical, industrial control systems wide range of applications and research fields. Easy to interface with your microcontroller

Product description:

  • To detect the ambient humidity
  • Adjustable sensitivity (shown in blue digital potentiometer adjustment)
  • Working voltage: 3.3V-5V
  • Provided with fixed bolt hole, convenient to install
  • The power indicator light and digital output indication lamp
  • Using LM393 chip, stable work


Panel interface description (3 Pins):

  • VCC external 3.3V-5V
  • GND external GND
  • DO small digital output interface (0 and 1)


Usage notes:

  • Humidity resistance module is the most sensitive on the environmental humidity, generally used for detecting the ambient humidity.
  • When module is not up to the threshold in the environmental humidity, the output port DO high level, when the environmental humidity exceeds a set threshold, module D0 output low level
  • Small digital output D0 is connected directly with the microcontroller, through the microcontroller to detect level, thereby detecting the humidity of the environment change
  • Small digital output DO can directly drive the relay module, which can be composed of a humidity control switch
