Once the water tank is full, turnoff motor at the right time is a daunting task. The most difficult thing is to put in the work and get to the switch immediately. I have also known people who had to fall back on their beds for three months. This circuit is the solution to this. Exactly two hundred rupees come ..

This is the circuit. Accordingly, if the water level of the tank falls below point B, the motor will be turned on. If the water level rises to the point C, the motor is turned off. So this is a tank level controller that is fully automatic. The mystery of this circuit is the timer IC 555, the wonder child of electronics. Depending on the user’s interest, a manual switch can be added for this. Many people may spoil what the need is. For example, some days the KSEB will be able to do this. Locally, an all-day power cut is imposed.

Suppose we have to turn the motor on before 9am. But if this circuit is attached to the motor, the motor will only turn on when the water level in the tank drops below point C. If there is half the water in the tank, the motor will not turn on and the water in the tank will be exhausted by midday. No problem .. Manual switch is the solution. Now let’s see how to attach it. For that, we need to understand how the 555 IC works in this circuit. If the supply voltage is connected to pin two, the IC output will not give. The resultant relay will be disabled. Motor does not work if relay does not work. When the water level drops from C, the supply voltage to pin 2 disappears. That’s when the IC outputs and the motor turns on. So our switch should be connected to the track that connects the pin number two and the supply voltage. Instead, it is a push to break switch.

This means that when the user presses, must turn the circuit on or off. Such switches are available in the market. Buy it and connect it to point C and pin number 2 as a manual switch. Then we can place the motor whenever we want. It’s just a click of a switch. Now for those who find it difficult to push a switch, an automatic braking switch can be attached to this circuit. The circuit below can be described as follows. The relay to use is not a normal relay. You need to get 30 amperes of capacity. Because a lot of current is used when the motors are on. Then the important thing to note is the sensing probes. Stainless steel is the best part to knock with water. If not, the corrosion will occur and the circuit will be deactivated.
