HR202 Humidity Sensor Module, 20-95% Humid Levels

This is a ready-to-use HR202 Humidity sensing module, which allowed humidity measurement. The DHT11 humidity sensor is a small and simple module that can be used with Arduino (or any other microcontroller, relay modules).

 

Features:

  • Humidity Range (20 to 95% at +-5% Accuracy)
  • Operating Voltage: 3.3V / 5Vdc
  • Digital Output
  • Adjustable Sensitivity
  • LM393 Comparator, Power Output and Digital Output Indicator
  • Low Power Consumption
  • Easy to use

 

 

Working of HR202 Humidity Sensor Module

This particular module picks up changes in the resistance value of the humidity sensor element in response to the change in the humidity and delivers a digital-level (high or low) output. The onboard multiturn trimpot can be used to set the detection threshold level. Two onboard LEDs indicate power input and signal output statuses.

 

  • HR202 detects the surrounding ambient humidity.
  • The sensitivity (humidity detection threshold) can be adjusted by onboard Potentiometer
  • Digital Output is obbtained using a LM393 comparator.
  • Output is high when humidity levels is above the humidity detection threshold value and vice versa.
