Ulaganathan 1 Azha Periasamy 2 E.

This project provides the development of mobile phone as remote control application for submersible motor pump which is used in agriculture irrigation. The motor connections depends upon its horse power, it may be Direct on line or Star Delta. The motor is controlled by the micro controller and the present status of motor is sensed and it is automatically controlled by itself and the information is transmitted to the corresponding person through GSM network. The GSM mobile phone is used as an alternative to turn on and off the motor through a message or a missed call and also to send message to the owner about the following three faults. A micro controller is used to detect the three types of fault which cause damage to the motor. The first one is single phase absence fault detection and if it occurs the micro controller will automatically turn of the motor. The micro controller also includes the protection against over current or over load and also from dry running. It is expected that this application will be comfortable for the farmers and this provides easy access of motor to a greater extent. All these control process are achieved by using a PIC microcontroller, GSM and Different interfacing and control circuits.

With the rapid development of agriculture in India, many automatic technologies have been introduced into agricultural productions. The total rainfall in a particular area may be either insufficient, or ill-timed. In order to get the maximum yield, it is essential to supply the optimum quantity of water, and maintain correct timing of water. This is possible only through a systematic irrigation system-by collecting water during the periods of excess rainfall and releasing it to the crop as and when it is needed. Irrigation is the science of planning and designing an efficient, low-cost, economic irrigation system tailored to fit natural conditions [1]. By the construction of proper distribution system, the yield of crop may be increased because of controlled water supply. The different methods of supplying water to the fields are Surface irrigation, Sub-surface irrigation and Sprinkler irrigation. The stored or diverted water is conveyed to the agricultural fields through some suitable distribution system. Hence, there are now pressing needs for intelligent irrigation system. The aim of this project is to develop a cost effective solution that will provide remote control for induction motors through mobile phones using missed calls and messages. The mobile user in the world has a tremendous rise during the past few years. Remote monitoring of processes, machines, etc., is popular due to advances in technology and reduction in hardware cost [2]. Remote monitoring through Internet based monitoring is one of common approach. This approach requires PCs (Client/Server) along with additional devices like modems, buffers, etc. for internet connectivity and software support for TCP/IP protocols and control system interaction. The cost of such system varies greatly depending on speed and bandwidth requirements and hence is justified usually for bio- medical and industrial applications where intensive data transfer is required. Cellular networks provide Short Messaging Service (SMS) and Multimedia Messaging Service (MMS), approach offers simple interface with only destination cell phone address and message requirement without any header / protocol overhead. So this method is suitable for remote monitoring of systems with moderate complexity. Wireless sensor networks also offer opportunity for remote monitoring [3] [6] [9]. II. PROBLEM OF STATEMENT Many farmers use induction motor pumps to irrigate their farms from wells, rivers and nearby streams. However, shortage of electric power in many states has resulted in unplanned load shedding of long durations in rural areas. Moreover, in villages, single-phasing connections have been implemented. The electricity companies allocate lower priority to 3-phase power supply to rural areas due to unpaid electricity bills running into millions of rupees. Most of farmers use sprinkler based or surface based irrigation. Three phase induction motors with direct-on-line or star- delta starters are used. For sprinkle based irrigation, farmer first arranges set of pipes with nozzles in the region of distribution of water and then switches on the pump. He waits for specific duration to ensure that water is distributed in sufficient quantity and then shifts the set of pipes to other dry regions and repeats the process. In many cases, the distance between location of pump (water source) and the region of distribution of water (farm) might extend to few kilometers. In case of power failure, farmer has to go back to pump region and wait for power restoration. For surface based irrigation, water is discharged through pipe at ground surface and gradient is created to distribute the water through the various regions. There are frequent instances of
