In fact the level of any conductive non corrosive liquids can be measured using this circuit.
Water level sensor circuit diagram.
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.
But initially it is connected to ground.
Water level indicator and alarm using uln2003.
Overflow of water is definitely a major problem nowadays.
Are you looking for an automated device to solve this problem.
When the water level is maximum this pin is enabled and this drives the 555 timer into astable mode.
Water level indicator circuit liquid level sensor with alarm.
The sensor can be easibly made out of a small piece of pcb that is etched with the proper pattern.
Circuit diagram we can consider this whole circuit as 4 small circuits each one for indicating alarming when a particular level a b c d of water have been reached.
When water level reaches to point a circuit with red led transistor q1 gets completed and red led glows.
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 circuit is based on 5 transistor switches.
The logic implemented in this circuit is 555 timer is enabled when its reset pin is connected to logic high.
Overflow water tanks eventually lead to loss of water and natural resources as well.
It is also possible to connect several sensors to the water level monitor circuit.
The decoupling capacitor c3 is a 100uf 16v electrolytic capacitor.
