The main controlling unit of the project is the PIC microcontroller. A rain sensor, DC motors, and a motor driver are interfaced with the PIC microcontroller. When rain falls on the sensor, it detects the presence of rain and sends a signal to the microcontroller. The microcontroller processes this signal and activates the DC motor through the motor driver to automatically cover the crops with a protective roof. When the rain stops, the system can operate the motor in the reverse direction to uncover the crops. The entire operation

Objectives:

1. To develop an automatic rain detection system using a rain sensor.
2. To protect crops from unexpected rainfall using an automatic movable roof.
3. To control the roof movement using DC motors and a motor driver.
4. To use a PIC microcontroller for automatic monitoring and control.
5. To reduce manual effort and protect agricultural crops from rain damage.
6. To implement the control system using Embedded C programming.
