non-contact capacitive liquid level sensor

BL-YW-SR-CL-61 water liquid level sensor

BL-YW-SR-CL-61
The photoelectric liquid level sensor is a non-contact capacitive sensor used to measure the level of liquid in a water tank. It detects changes in liquid level by using the photoelectric principle. When the liquid covers or does not cover the position of the photoelectric sensor, the transmission and reception state of light changes, thereby detecting the height of the liquid level. Photoelectric liquid level sensor is suitable for various liquids, such as water, oil, chemical liquids, etc.

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.
