ABSTRACT:

Wireless Water Level Controller With Percentage Display On Lcd(Rf Based) is designed to overcome the problems of turning ON and OFF water pump for filling water tank. This system is fully automatic and very compact in size. In ordinary water tank system, there is needed long wire to connect sensor from overhead water tank mounted on the uppermost roof of the building. This creates very wiry system. However, this system is built with wireless transmission system. This system show you current status of tank in LCD didplay as percentage i.e. 0%, 25%, 50%, 75% and 100%. It also automatically turn OFF water pump motor and turn ON buzzer alarm.

TECHNICAL DETAILS:

MICROCONTROLLER: It takes input and after processing it gives required output.

WATER SENSOR: water sensors are conducting wires. These wires are deep in water. One of these wires is positive voltage or negative and others are input of amplifier circuit.

TRANSFORMER: Here step-down transformer is used to power electronics circuits.

RELAY: relays are electromagnetic switches used to switch high power signal through a small signal.

RF TRANSMITTER AND RF RECEIVER: RF Transmitter And RF Receiver are wireless communication device that used radio frequency as carrier frequency.

ADVANTAGES:

1. No need to look after water tank for overflow.
2. Save your electricity bill.
3. Prevent wastage of water.
4. Taking care of availability of water, anytime.
5. Tension free from switch ON or OFF of water pump.
