Water Level Sensor Circuit With Relay Switch

The sensor produces an output voltage according to the resistance which by measuring we can determine the water level.

Water level sensor circuit with relay switch.

The circuit is ideal for automatically switch off the water pump when your water tank pool or aquarium is filled. The sensor can be easibly made out of a small piece of pcb that is etched with the proper pattern. This circuit measures or detects a required level of water liquid or any fluid. The controller responds depending upon the relevant levels of water in the tank and the position of the immersed sensor points.

The less water the sensor is immersed in results in poor conductivity and will result in a higher resistance. The article explains 5 simple automatic water level controller circuits which can be used for effectively controlling the water level of a water tank by switching the pump motor on and off. In this tutorial we are going to make a simple water level sensor or liquid level detector circuit. How does the water switch circuit works.

Here is a schematic of a simple water or liquid level sensor relay switch circuit which can be used to switch on or off electronic appliances at the desired level of water.

Water level sensor pinout. When water hits the sensor the reference voltage is overshot and the ic drives the ceramic transducer to beep. It is also possible to connect several sensors to the water level monitor circuit. Many conceptually good water controller level circuits fails practically as the pass dc current through the water through their sensors which corrodes sensors made up of any conductive materials be it al cu stainless steel or the tinned one.

Learn about the different types of water level sensors and how they work.
