  • Rs. 190.00 INR


The HR202 Humidity Sensor Module can be applied to the storagecompartment, indoor air quality control, building automation, medical,industrial control systems wide range of applications and research fields. Easyto interface with your micro-controller


Product description:

  • To detect the ambient humidity

  • Adjustable sensitivity (shown in blue digital potentiometeradjustment)

  • 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 (4 line):

  • VCC external 3.3V-5V

  • GND external GND

  • DO small digital outputs interface (0 and 1)


Usage notes:

  • Humidity resistance module is the most sensitive on the environmentalhumidity, 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 setthreshold, module D0 output low level

  • Small digital output D0 is connected directly with themicro-controller, through the micro-controller to detect level, thereby detectingthe humidity of the environment change

  • Small digital output DO can directly drive the relay module, which canbe composed of a humidity control switch
