Project: Automated Irrigation System Responsibilities:

Tools : MP LAB, PROTEUS

In this project, the nature of the land will be monitored using different types of sensors. The water will be pumped and poured into the plants automatically based on the sensor values. Simultaneously the level of the water will also be monitored. If the water level reaches high then the motor will go to the OFF state automatically. The ON/OFF state of the motor to the land moisturizing condition will be sent to the owner through SMS using GSM.

Responsibilities:

• Developed the Code and Simulation
• Prepared Test cases
• Done Software and Hardware testing.
