Specifications

Introduction

  • Using high-quality HR202 humidity sensor;   
  • The comparator output signal waveform, clean, good, strong drive ability, more than 15mA.
  • With a potentiometer to adjust temperature detection threshold
  • Working voltage 3.3V-5V
  • Output: digital switch output (0 and 1)
  • A fixed bolt holes, easy to install
  • Small PCB size: 3.2cm x 1.4cm
  • The use of wide voltage comparator LM393  

Instructions for use:

  • Humidity sensor module is very sensitive to the environment humidity, generally used to detect the humidity of environment;
  • Through the regulation of the potentiometer, can change the humidity detection threshold (i.e. control humidity), such as the need to control the environmental humidity is 60%,Module in the corresponding environmental humidity adjusting the green light, DO outputs high level, below the setting humidity value, high output, light is not bright;
  • The DO output can be directly connected with the MCU, the MCU to detect high level, thereby detecting the humidity of the environment change;
  • The output of the DO can directly drive the relay module, which can be composed of a humidity switch, control related device in an appropriate working environment;
