Simple Water Level Sensor Circuit

Whenever tank gets filled we get alerts on particular levels.

Simple water level sensor circuit.

This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank. In this circuit this circuit uses a liquid level sensor to measure the level of water in the water tank. 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. In fact the level of any conductive non corrosive liquids can be measured using this 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. The circuit is very simple to build with the microcontroller and also using basic electrical and electronic components. This simple water level sensor circuit monitors the presence of water in a certain location or container. It is very simple to build and it is made of a single ic and some passive components.

This is the circuit diagram of a simple corrosion free water level indicator for home and industries. Here we have created 4 levels low medium high and full we can create alarms for more levels. The circuit produces the sound when the sensor senses a drop of a water leak. The circuit is based on 5 transistor switches.

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