Product Applications of relay NO point output:
1. When the black wire is connected to VCC:
When the liquid is sensed, the relay is closed, the NO point of the relay is turned on, and the VCC voltage is output;
When no liquid is sensed, the relay is disconnected, and the relay NO point is disconnected.
2. When the black wire is connected to GND:
When liquid is sensed, the relay is closed, the NO point of the relay is turned on, and the GND voltage is output;
When no liquid is sensed, the relay is disconnected, and the relay NO point is isconnected.
