Water level indicator is a device which receives the records approximately the water degree in tanks that’s used in homes and public places. We can control wastage of water with overflow of water tanks by way of the usage of the tank level indicator. As every one understand when the water is saved in the tank, no one can discover the real stage of water within the water tank. This is manner ordinarily water tank overflow and its outstanding loss of water as well as energy.

Water level indicator

Water Level Indicator with Alarm

On this simple water stage indicator project we’ve got used a Switching IC ULN 2003 to indicate the water inside the tank. Now a days many initiatives on water indicator are to be had such as slope indicator water level meter, digital water stage indicator, Water stage indicator the use of transistors,water level indicator alarm and and so on.

Water Level Indicator using IC ULN2003

On this circuit we are the use of switching IC ULN 2003 usually used switching IC. Components used in this useful projects are as:

ULN2003 is a excessive modern-day and high voltage Darling-ton array IC. It includes 7 open collector darling-ton pairs with common emitters. Darling-ton pair is an arrangement of 2 bipolar transistors. It’s far a relay driving force IC other kinds of comparable ICa are high aspect toggle transfer, low side toggle transfer, Darlington transistor, bipolar NPN transistor,. N-channel MOSFET, ULN2003 motive force IC and so forth.
LED s this ic has 7 output pins that is manner we are going to use 7 LEDs as water stage indicator inside the tank. These LED s will glow in step with the level of water in the tank.
Battery: A DC supply of 9Volt DC is given through a battery to electricity up the circuit or you may use nine to 12v DC deliver as power.
Resistance 220ohm resistors are used in this Project to defend the LEDs due to the fact we’re the usage of nine volts to 12 volts electricity deliver.

Circuit Diagram of final tasks

Water Tank stage Indicator

I this following animated circuit diagram we have cleared all components with their connection you could use lengthy wires in keeping with the distance of your tank to electric board.

Water stage Indicator the usage of Alarm


We also can use alarm with this circuit. It’ll alert you that now the tank is complete and you must flip off the water pump.

Tank level Indicator auto Powered off


We also can use a cut off Relay with this circuit, while the Tank may be complete relay will cut off the power robotically.

Water Tank level indicator

On this circuit given approximately we have cleared all connections with vehicle cut off water pump when tank could be complete water Pump will automobile turn off because a relay is hooked up with 7th output of ic.
