Connect the sensor as described above, and the signal end will output a voltage signal that is consistent with the water level condition. This signal is used as a liquid level control signal to connect to the MCU (microcontroller) I/0 port. When the liquid level exceeds the critical liquid level and submerges the sensor body, the signal output is low voltage. When the liquid level is below the critical liquid level and the sensor body is exposed, the signal output is high voltage.
