ABSTRACT

In past few years, automatic irrigation system has seen a rapid growth in terms of technology. At present cost-saving technology, labor-saving are the addressing key issues in irrigation. This paper gives a review of these systems based on existing technologies and also proposes an economical and generic automatic irrigation system based on wireless sensors with GSM-Bluetooth for irrigation system controller and remote monitoring system. This system has simpler features designed with the objective of low cost and effective with less power consumption using sensors for remote monitoring and controlling devices which are controlled via SMS using a GSM module. A Bluetooth module is also interfaced with the main microcontroller chip. This Bluetooth module eliminates the usage charges by communicating with the appliances via Bluetooth when the application is in a limited range of few meters. The system informs user about any abnormal conditions like less moisture content and temperature rise, even concentration of CO2 via SMS from the GSM module or by Bluetooth module to the farmer’s mobile and actions are taken accordingly by the farmer. In future, the farmer will be able to monitor and control the parameter by GSM and Bluetooth technologies.

PURPOSE: The purpose of this project is to improve the irrigation system of Indian agriculture and also to provide adequate irrigation to particular area..

PROJECT DESCRIPTION:

The design presented has the advantage of both GSM and Bluetooth technology and the sensors and devices are controlled by both by using Bluetooth when in a limited range with the appliances and using SMS for remote monitoring and control thereby reducing the usage charges of GSM.

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.

TECHNOLOGY:

GSM:

GSM (Global System for Mobile communications) is the technology that underpins most of the world’s mobile phone networks. The GSM platform is a hugely successful wireless technology and an unprecedented story of global achievement and cooperation. GSM has become the world’s fastest growing communications technology of all time and the leading global mobile standard, spanning 218 countries. GSM is an open, digital cellular technology used for transmitting mobile voice and data services. GSM operates in the 900MHz and 1.8GHz bands GSM supports data transfer speeds of up to 9.6 kbps, allowing the transmission of basic data services such as SMS.
