Now people pay great attention to the problem of drinking water health, so many families choose to install water purifier equipment, and the role of the water level sensor in the water purifier is to detect the water level height of the water tank.
The capacitive liquid level sensor has built-in MCU and adopts signal processing technology to determine whether the water tank is short of water by sensing the difference of capacitance value between water and no water. The capacitive liquid level sensor is installed on the outer wall of the insulated water tank, and can be detected without direct contact with the liquid. If the low liquid level is detected, then the sensor is installed at the bottom or below of the water tank; if the high liquid level is detected, then the sensor is installed above the water tank. Capacitive liquid level sensor is small in size, easy to install, does not need to open the container, and can detect the liquid in the closed container. Because the capacitive liquid level sensor does not directly contact the liquid, so there is no big requirement for liquid medium
