1.5 METHODOLOGY
Here, we use a PIC Microcontroller which controls the Relay that turns ON/OFF the water pump and sends a signal of display to an LCD screen to indicate the level or quantity of water available in an overhead tank. The Water Level Sensing Section senses the level of water in the tank and sends signal to the Receiver Section. Receiver Section is connected to the Controlling Section, which process the received information and produces visual, sound indications and controls the operation of the motor whenever required. The project is divide into 4 sections.
1. Power Supply Section: Power Supply section provides required power supply for Receiver and Controlling modules.
2.Water Level Sensing Section: Level Sensor module senses the water level and sends a signal of the level to the receiver section for further process.
3. Receiver Section: The data transmitted by the Sensor module is received and is given to the Controlling Module.
4. Controlling Section: The soul of the Controlling Section is an ATMEL microcontroller. It processes the data given by the Receiver Section. Turns ON/OFF the water pump, sends signal of display to the LCD for the display of the water level and the water pump status according to the data it receives.
A program is written in C language to control the microcontroller which will enable it perform the task of its purpose. Which includes, receiving a signal from the water level sensor as INPUT, deciding using logic gates whether or not the water pump requires to be turned ON or OFF, sending a signal of display to the LCD as OUTPUT, and finally turning ON and OFF of the water pump as OUTPUT depending on the water level (if LOW or FULL respectively).
1.6 SCOPE AND LIMITATION OF THE STUDY
The system to be developed in this project will be used to control the water level in an overhead tank in order to avoid wastage of water. A program will be written in C language to automatically turn ON water pump when the level of water in the overhead tank is LOW and automatically turn OFF the water pump when the tank is FULL and display the water level on an LCD screen using microcontroller, therefore, cannot work in the absence of electricity. It is significant to know that this design is limited to 12v, 5amps electric pump and cannot be used to control industrial water pumps above 5 amps. This is due to the cost of the big length power generator and bigger sensor, therefore, the lower ones will be used. Time limitation also contributed to the loose current.
