AGRICULTURE PROJECTS-EMBEDDED SYSTEM BASED GSM COMMUNICATION FOR AUTOMATIC IRRIGATION CONTROL SYSTEM

  1. 1. EMBEDDED SYSTEM BASED GSM COMMUNICATION FOR AUTOMATIC IRRIGATION CONTROL SYSTEMIEEE Reference: Wireless sensor network based remote irrigation control system and Automation using DTMF code.Abstract: Agriculture is a source of livelihood of majority Indians and has great impact onthe economy of the country. In dry areas or in case of inadequate rainfall, irrigationbecomes difficult. So, it needs to be automated for proper yield and handled remotely forfarmer safety. In this paper we suggest a Wireless sensor network and Embedded basedtechnique to control water flow for sectored, sprinkler or drip section irrigation. Thissystem will be very economical in terms of the hardware cost, power consumption andcall charges. In places such as agriculture lands, there is a continuous need for monitoring thewater level at particular places. In places such as drip irrigation for coconuts and bananas,the water is let out through pipes directly to each field. A person has to carefully monitorthe water level at regular intervals. His job becomes tedious during night times and forfrequent power cuts. Sometimes there is wastage of water and electricity due tonegligence and other times there is a hard job for the user. The project helps inautomating this job. This is highly helpful in places such as drip irrigation system where there aremany flow pipes but does not require any change in the agricultural fields. Further thereis a wireless communication device consisting of very high frequency transceiver. Ithelps to coordinate any action between the controlling authority and the fields. So eachfield can be placed as a separate wireless node and these field transceivers act as a highspeed wireless network. The project proposes a water level sensor at each place where the water has to bemonitored. When the motor is switched on the sensors are activated and the fields areirrigated automatically. Once the water reaches a particular level which may even takehours, the system takes appropriate steps to regulate or even stop the water flow. The farmers’ job gets over immediately after switching the power supply. Thecircuit also monitors the water in the well/bore well so that if the water level goes verylow it switches off the main motor to prevent dry run and also to prevent damage to themotor.
  2. 2. The project houses a high speed microcontroller and water sensors at differentfields and inside the well. These sensors are attached to the microcontroller and arecontrolled accordingly using motor and water control circuits. The microcontroller used is a high Speed microcontroller for fault free operation.It has a variety of advantages over conventional old microcontrollers such as RISCarchitecture, larger memory word, fast operation and a host of inbuilt features such asADC, communication protocols etc., The project also houses a GSM modem where the user can easily be notified byany fault in the system or if all fields are properly irrigated or if there is no sufficientwater in the well. The same can be used to switch on the system and off by simplysending an SMS. This scheduling helps greatly because as agriculture power supplies areprovided only at a particular time of day and not all hours. This is highly helpful in placesif the user is out of his home for any purpose or his home is far away from hisagricultural land which is a common scenario. This helps in precious saving of water and electricity and eases the job of theperson. The project can be used in large agricultural lands, coconut plantations and manyother plantations and even in home environment or industries and colleges where thereare large gardens to monitor and irri gate them automatically.
