Water level marker is a framework which gets the data about the water level in tanks which is utilized in homes and open spots. We can control flood of water tanks by utilizing the tank level marker. As each body know When the water is put away in the tank, no body can recognize the genuine degree of water in the water tank. That is way for the most part water tank flood and its incredible loss of water just as power.

In this straightforward water level marker venture we have utilized a Switching IC ULN 2003 to show the water in the tank. Presently a days numerous ventures on water pointer are accessible, for example, incline marker water level meter, Digital water level marker, Water level marker utilizing transistors,water level pointer alert and so on.

Water Level Indicator Using IC ULN 2003

In this circuit we are utilizing exchanging IC ULN 2003 regularly utilized exchanging IC. Segments utilized in this Projects are as:

ULN2003 is a high present and high voltage Darling-ton cluster IC. It comprises of seven open authority dear ton sets with basic producers. Sweetheart ton pair is a game plan of two bipolar transistors. It is a transfer driver IC different kinds of comparative ICa are high side flip switch, low side flip switch, Darlington transistor, bipolar NPN transistor, N-channel MOSFET, ULN2003 driver IC and so on.

Driven s this ic has 7 yield sticks that is way we are going to utilize 7 LEDs as water Level pointer in the tank. These LED s will shine as per the Level of water in the tank.

Battery: A DC supply of 9V is given through a battery to catalyst the circuit or you can utilize 9 to 12v DC supply as power.

Resistor 220 ohm resistors are utilized in this circuit to secure the LEDs since we are utilizing 9 volts to 12 volts power supply.

Circuit Diagram of final projects

I this following vivified circuit chart we have cleared all parts with their association you can utilize long wires as per the separation of your tank to electric board.

Water Level Indicator Using Alarm

We can likewise utilize alert with this circuit. It will Alert you that now the tank is full and you should mood killer the water siphon.

Tank Level Indicator Auto Powered off

We can likewise utilize a Cut off Relay with this circuit, When the Tank will be full transfer will remove the power consequently.

In this circuit given about we have cleared all associations with auto cut off water siphon When tank will be full water Pump will auto mood killer on the grounds that a transfer is associated with seventh yield of ic.
