WATER LEVEL CONTROLLER FOR IRRIGATION
This project aims at building a water level controler which controls the level of the water in a field. The major components used in the project are PIC microcontroller, motor, sensor etc. Th elevel of water is sensed by the sensor and communicated to the PIC which then produces the control signals to run the motor to control the level of the water. If no water is present in the field, the microcontroller turns the motor on so that it is run for a particular period of time till the water is filled in the field. When sufficient amount of water has been filed, the controller turns the water off.
SENSOR
two conductors placed in the field detects the level of water in the field.
MICROCONTROLLER
The microcontroller employed in the project is Pic16c73s. The control signals are sent to the motor according to the input from the sensors. Teh controller also enables the LCD display. The motor
is controlled by a relay mechanism.
MOTOR
The microcontroller switches the motor on or off using the relay. A DC motor with a high starting torque is employed in the system
DISPLAY
It is used to display the current stste of the motor. The 16x2 LCD display is used.
