High and low level output drive small relay (coil current
≤
100mA) working principle:
When the liquid is sensed, the transistor will cut off and output a high level, and the relay will not pull in when it is
powered off;
When no liquid is sensed, the transistor is turned on and outputs a low level, and the relay is energized and pulled
inSimplified schematic diagram of NPN output wiring principle.
