It is very simple to build and it is made of a single ic and some passive components.
Simple water level sensor circuit.
The circuit produces the sound when the sensor senses a drop of a water leak.
The circuit sends an acoustic alarm when it senses a drop of water leak.
In this circuit this circuit uses a liquid level sensor to measure the level of water in the water tank.
Check out the water level indicator circuit too.
This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank.
The circuit is based on 5 transistor switches.
This circuit measures or detects a required level of water liquid or any fluid.
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.
The circuit is very simple to build with the microcontroller and also using basic electrical and electronic components.
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.
This is the circuit diagram of a simple corrosion free water level indicator for home and industries.
