Capacitive Water Level Sensor Circuit Diagram. Whenever tank gets filled we get alerts on particular levels. This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank.
A capacitive liquid level sensor utilizes capacitive principles to sense the level of a liquid contained within a receptacle. As a liquid rises and falls in the container the dielectric effect of the liquid changes the effective capacitance of a sensing capacitor which is detected by electronic circuitry coupled to the sensor. It is this difference that will be measured with the capacitive level sensor.
This project a capacitive liquid level sensor from 1989 uses an ingenious technique where the senor is located outside the liquid container.
Capacitive water level sensor fun to make. This is a very useful technique and has been used in later designs to create a portable liquid level sensor for locating the exact height of liquid in a plumbing system. This project a capacitive liquid level sensor from 1989 uses an ingenious technique where the senor is located outside the liquid container. As a liquid rises and falls in the container the dielectric effect of the liquid changes the effective capacitance of a sensing capacitor which is detected by electronic circuitry coupled to the sensor.
