When the water level is maximum this pin is enabled and this drives the 555 timer into astable mode.
Water level sensor circuit diagram.
This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank.
Overflow of water is definitely a major problem nowadays.
Whenever tank gets filled we get alerts on particular levels.
Are you looking for an automated device to solve this problem.

Water level indicator circuit liquid level sensor with alarm.
Water level sensor circuit diagram.
The water level indicator circuit diagram monitors the level of water in the tank and simultaneously switches on the water pump whenever the water level goes low in the water tank.
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.
In fact the level of any conductive non corrosive liquids can be measured using this circuit.
Here we have created 4 levels low medium high and full we can create alarms for more levels.
The circuit is based on 5 transistor switches.
The sensor can be easibly made out of a small piece of pcb that is etched with the proper pattern.
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.
