The HR202 Humidity Detection 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 micro-controller.


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 micro-controller through the micro-controller to detect high and low, thereby detecting the humidity changes in the environment.

DO output of the relay module can directly drive the shop, which can form a humidity switch, control-related equipment to work in the right environment.

Small plates AO analog output modules can be connected OUR AD through the AD converter, you can get a more accurate numerical ambient humidity With the screw holes of 3mm, easy fixed installation.

Pin interface description :

  • VCC external 3.3V-5V

  • GND external GND

  • DO small digital outputs interface (0 and 1)

Package Includes:

  • 1 x HR 202 Humidity Detection Sensor Module

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 micro-controller, through the micro-controller 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
