LM393 Chip HR202 Testing Detection Humidity Sensor Module
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 format : Digital switching output ( 0 and 1 )
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
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 ;
