Description:

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:

1.Humidity sensor module is very sensitive to the environment humidity, generally used to detect the humidity of environment;

2, through the regulation of the potentiometer, can change the humidity detection threshold (i.e. control humidity), such as the need to controlthe 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;

3, the DO output can be directly connected with the MCU, the MCU to detect high level, thereby detecting the humidity of the environmentchange;

4, the output of the DO can directly drive the relay module, which can be composed of a humidity switch, control related equipment in an appropriate working environment;
