Step by Step tutorial that how to make Water level controller by using Arduino Uno

"Motor ON when the water level goes below a predetermined level & Motor OFF when the water level goes up  a predetermined level "
The Heart of this project is Arduino Uno by using Arduino Analog Pins such as A0,A1,A2,A3,A4, we can sense the Water level There is a Transistor 2N222 connected with the Pin no 8 of the Arduino which can Turn On and Off the Relay by Receiving Signals From the Arduino Analog pin e.g +5v (1) Turn on Relay and 0V(0) Turn Off Relay The Relay play a role of Magnetic switch to On and Off The Motor or any kind of Load but the Relay is Dependent on Transistor .
This is Do it You self Project if you found any Difficulty while making this Project don't hesitate to ASK.

  1. Hi,
    Nice circuit. But one question: doesn't the contacts change their electrical values by electrolyse and corosing at long time measurement ?
