12V power supply stable version of Humidity sensor module
Use:
Humidity detection, humidity sensor, environmental humidity detection, with relay output, direct control of the power supply of the relevant equipment
Module characteristics:
1,High quality HR202 humidity sensor, with relay, direct control of the load
2, with potentiometer sensitivity adjustment, by adjusting the potentiometer, set the starting relay threshold, when the humidity is greater than this threshold value, module and relay, less than this threshold value, the relay is released.
3, using the 12V power input eclusively for relay, onboard 78l05 regulator triode, provide sensor comparator, make the product more stable and reliable;
4, output forms: AC 220V loads directly 10A or DC30V 10A
5, small size: 6cm 1.9cm PCB
6, the use of wide voltage comparator LM393
Electrical parameters:
Supply voltage: 12VDC current: more than 100mA
Load: 250V 10A AC or 30V DC 10A
