The aim of the project is to design an automotive rain operated roof to protect the field crops from rain. 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.
