The main aim of this project is to design low cost cell phone based Embedded System for Irrigation.
The purpose of this project is to provide cell phone based embedded system for irrigation to reduce the manual monitoring of the field and get the information in the form of SMS.
Appropriate environmental conditions are necessary for optimum plant growth, improved Crop yields, and efficient use of water and other resources. Automating the data acquisition Process of the soil conditions and various climatic parameters that govern plant growth allows information to be collected at high frequency with less labor requirements.
This project is developed mobile phone based remote control application for induction motor-pump based irrigation in agriculture.
In order to prevent dry running of motor and allow automatic restart of motor when sufficient water level is regained. Whenever water falls below LL level, microcontroller switches OFF the motor and sends SMS indicating empty well (dry running) conditions. The micro-controller switches ON the motor again when ever water rises beyond HL level and sends sms indicating resumption of task. Using analog voltage inputs for LL and HL levels increases the flexibility of system by just incorporating different threshold levels in program for different soil conditions.
In both conditions (water level sensor) protection for induction motor. However, in order to ensure maximum reliability, one temperature sensor is mounted on body of motor, to measure ambient temperature whenever temperature difference exceeds specified safety limit, signal is sent to switch OFF pump along with error indication to LCD display and conveying SMS to user cell phone to indicate probable fault occurrence. We are using soil moisture sensor placed at the plants to know how much water content is present in the field
Generally frequent power cuts and insufficient rains at various stages of growth are one of major causes of losses to farmers. Many farmers use induction motor pumps to irrigate their farms from wells. In this application, GSM modem receives any incoming SMS message is directly routed to micro-controller and any outgoing text message is directly sent by micro-controller to designated cell phone number without being stored in control system cell phone memory. As a result, phone memory is not in undated with messages in spite of many messages being transferred.
