Adjust the sensitivity with the potentiometer. Set the start relay threshold by adjusting the potentiometer. When the humidity is greater than the threshold, the module relay pulls in. When the threshold is less than this threshold, the relay is released. 3, 12V power input for relay use, onboard 78L05 regulator triode, provide sensor comparator, make the product more stable and reliable; 4. Output form: load directly connected to AC 220V 10A or DC30V 10A 5, small board PCB size: 6cm x 1.9cm 6, using a wide voltage LM393 comparator
