This project is developed for the users to control the overflow of water in the Tank in wireless manner. The device will automatically switch off the pump when the highest level is reached.
In the tank, there are four probes and a four channel RF transmitter are connected. When water reaches a particular level, the RF transmitter sends signal accordingly.
A four channel RF receiver is connected with a microcontroller circuit. The RF receiver receives signal and sends to the microcontroller. The microcontroller sends signal to the LCD. If the water reaches the higher level, the microcontroller sends signal to the controlling circuit to stop the motor.
Since this uses RF signal, there is no need of wire from tank to the motor controlling circuit.
The microcontroller used is PIC 16F73 and the microcontroller program is written in assembly language
