Simple Water Level Sensor Circuit

The circuit sends an acoustic alarm when it senses a drop of water leak.

Simple water level sensor circuit.

This circuit measures or detects a required level of water liquid or any fluid. This simple water level sensor circuit monitors the presence of water in a certain location or container. The circuit diagram is quite simple with only a few components but it can perform a great number of tasks as a monitor for the desired level of any fluid. The circuit is very simple to build with the microcontroller and also using basic electrical and electronic components.

Check out the water level indicator circuit too. 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. This is the circuit diagram of a simple corrosion free water level indicator for home and industries. The circuit produces the sound when the sensor senses a drop of a water leak.

In this tutorial we are going to make a simple water level sensor or liquid level detector circuit. 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. It is very simple to build and it is made of a single ic and some passive components.

In fact the level of any conductive non corrosive liquids can be measured using this circuit.
