Diy Automatic Water Level

It’s an automatic switching circuit that used to control an AC water pump. Operation of this circuit is simple.wen the water level goes below the limit the lower level sensor will detect it and activate the water pump.wen the water level reaches the upper limit the upper limit sensor detect it and switch of the water pump

“To make a cheap but efficient water level controller under $1 budget to control AC water pump”

To make this circuit you will need

BC 547 Transistor X 3 = 9 INR

220 K Ohm & 5.4 K Ohm resistors = 1

1N4007 Diode = 1

12V relay = 12

One, 3-pin PCD connector & two, 2-Pin PCB connector = 25

Wires = 5

PCB = 12
