The project aims in designing a system which is capable of detecting moisture level in the soil, temperature at field and will be display on LCD. This project makes use of an onboard computer, which is commonly termed as micro controller. It acts as heart of the project. This onboard computer can efficiently communicate with the output and input modules which are being used. The controller is provided with some internal memory to hold the code. This memory is used to dump some set of assembly instructions into the controller. And the functioning of the controller is dependent on these assembly instructions. The main controlling device of the project is PIC Microcontroller. Temperature sensor, soil moisture sensor and LCD is interfaced to the microcontroller. Microcontroller will continuously read the data from sensors and will be display on LCD module. To achieve this task microcontroller loaded program written in embedded C language.        

The major features of this project are:  

• Automatic sensing of temperature and moisture.
• Simple electronic circuit.
• Displays the sensors data on LCD module.

           

The major building blocks of this project are:  

1. Regulated Power Supply.
2. PIC Microcontroller.
3. Soil moisture sensor.
4. Temperature sensor.
5. LCD display.
6. Crystal oscillator
7. LED Indicators.
8. Reset.

         

Software’s used:    

• PIC-C compiler for Embedded C programming.
• PIC kit 2 programmer for dumping code into Micro controller.
• Express SCH for Circuit design.
