1pcs Humidity r Module HR202

1pcs Humidity r Module HR202

Application:

Humidity testing, humidity r, ambient humidity detection

Module Features:

1, using high quality HR202 humidity r;

2, the comparator output signal clean waveform is good, driving ability, than 15mA.

3, adjust the temperature distribution bit detection threshold

4, Working voltage 3.3V-5V

5, the output form: DO digital switching outputs (0 and 1) and AO og voltage output

6, with bolt holes for easy installation

7, a small board size: 3.2cm x 1.4cm

8, using a wide voltage LM393 comparator

Module for use

1, the humidity r module is sensitive to humidity, generally used to detect ambient humidity;

2, through the adjustment of the potentiometer, can change the humidity detection threshold (that is, control humidity values), if eary to control humidity of 60%, the humidity in the corresponding module is set to its green light, DO output is HIGH level falls below the set humidity value, the output is high, the green light does not shine;

3, DO output can be directly conted with the microcontroller through the microcontroller to detect high and low, thereby detecting the humidity changes;

4, DO OUR outputs can directly drive the relay module, which can be composed of a humidity switch, control related equment in proper working environment;

5, small plates og output AO can shop AD module conted through the AD converter, you can get more accurate humidity values;
