AIM:The purpose of this project is to design a system which monitors and controls the water flow to an irrigation system using Mobile Phone through SMS. This can be achieved by the use of soil moisture sensor, which senses the water content in the soil. This sensor output is given to a Microcontroller based control system for further data processing. The system also used to design and construct a solar tracker system that follows the sun direction for producing maximum output voltage for solar powered applications. This project consists of few sun light sensors LDR sensor and a motorized mechanism for rotating the panel in the direction of sun. Microcontroller based control system takes care of sensing sunlight and controlling the motorized mechanism. This system works continuously without any interruption.
Descriptionj:This project also consists of GSM modem for remote monitoring and control of water supply to irrigation system. Whenever the soil moisture content goes below some predefined level, and then this information is sent to user as an SMS message over GSM network. After receiving this SMS alert user can send commands in the form of SMS message back to Microcontroller based control system. Based on the command received the Microcontroller switches ON or OFF the electrical water pump. This project consists of few sun light sensors and a motorized mechanism for rotating the panel in the direction of sun. Microcontroller based control system takes care of sensing sunlight and controlling the motorized mechanism. This system works continuously without any interruption. The main controlling device of the project is Microcontroller to which LDR's sensor and geared DC motor with panel setup to its shaft are interfaced. The Microcontroller gets input from LDR sensors regarding the direction of sun and controller process this information and controls the movement of solar panel attached to DC motor. This achieves the goal of tracking sun. The Microcontroller is programmed using powerful Embedded C language.
The design of this system is very much sensitive and should be handled with utmost care because the microcontroller is a 5 volts device and it is employed to monitor the operation of high voltage DC water motor. So every small parameter should be given high importance while designing the interfacing circuit between the controller and the water motor.
