Humidity Sensor Module HR202 Humidity Module Humidity Detection
Product information
Description:
Application:
Humidity testing, humidity sensor, ambient humidity detection
Module Features:
1, using high quality HR202 humidity sensor;
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 analog voltage output
6, with bolt holes for easy installation
7, a small board PCB size: 3.2cm x 1.4cm
8, using a wide voltage LM393 comparator
Module for use
1, the humidity sensor 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 necessary 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 connected 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 equipment in proper working environment;
5, small plates analog output AO can shop AD module connected through the AD converter, you can get more accurate humidity values​​;
