Simple Water Level Sensor Circuit

The circuit is based on 5 transistor switches.

Simple water level sensor circuit.

This simple transistor based water level indicator circuit is very useful to indicate the water levels in a 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. 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.

Here we have created 4 levels low medium high and full we can create alarms for more levels. Whenever tank gets filled we get alerts on particular levels. Check out the water level indicator circuit too. In fact the level of any conductive non corrosive liquids can be measured using this circuit.

This circuit measures or detects a required level of water liquid or any fluid. In this circuit this circuit uses a liquid level sensor to measure the level of water in the water tank. The circuit sends an acoustic alarm when it senses a drop of water leak. In this tutorial we are going to make a simple water level sensor or liquid level detector circuit.

The circuit is very simple to build with the microcontroller and also using basic electrical and electronic components.
