In fact the level of any conductive non corrosive liquids can be measured using this circuit.
Water level sensor circuit diagram.
Overflow water tanks eventually lead to loss of water and natural resources as well.
The decoupling capacitor c3 is a 100uf 16v electrolytic capacitor.
This is the circuit diagram of a simple corrosion free water level indicator for home and industries.
The circuit is based on 5 transistor switches.
Are you looking for an electronic solution to resolve this issue.
Whenever tank gets filled we get alerts on particular levels.
Here we have created 4 levels low medium high and full we can create alarms for more levels.
Water level indicator circuit liquid level sensor with alarm.
Overflow of water is definitely a major problem nowadays.
This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank.
Water level sensor circuit diagram.
Water level indicator and alarm using uln2003.
It is also possible to connect several sensors to the water level monitor circuit.
When the water level is maximum this pin is enabled and this drives the 555 timer into astable mode.
Are you looking for an automated device to solve this problem.
But initially it is connected to ground.
The water level of the tank is indicated by using the 5 led s and if the water level in the tanker is full then the water pump is turned off completely.
