agriculture automation to flourish and deliver its full potential. To get more benefits of these technologies, we should not just consider the implication of developing a new single technology but should look at the wider issues for complete development of a system. This system designed by using LPC2148 microcontroller to overcome limitations of agriculture farming about supplying of water to plants by drip system with the available water tables. In our system we use LPC2148 microcontroller, motor pump, soil moisture sensor. The motor pump operates based on soil condition that is soil wet or dry; if soil wet motor stops else motor run to give water to plants. The status of motor displayed on first row of LCD There is also a rain sensor whenever rain fall occur then also motor off irrespective of soil condition. The temperature and dangerous CO gas also verified by using different sensors connected to controller. In case any critical situation occurs through these sensors an SMS sent to owner. An electrical fence also included to keep strangers away from field by its slight shock. Authorized persons presence identified by using RFID module interfaced to controller when RFID card carried by that person near field. In this case electrical fence deactivated hence no shock by fence.
Keywords: LPC2148, soil moisture, temperature, rain, Co sensors, RFID module, electrical fence, GSM, motor pump.
1. Introduction Irrigation is the major problem in agriculture in the countries which are in developing stage. In any country which is like India where the income of people depends on agriculture directly or indirectly and the environmental conditions are isotropic still we are unable to use agriculture resources. The main cause low rainfall due to this more land not irrigated. Another very important reason unplanned usage of water resources by this way more water goes waste. By the drip system water supplied to plants zone only remaining area can’t get water due to this large amount of water saved. Automatic irrigation system can supply water to plants whenever they need water when power supply intervals. Here no need of turning ON/OFF valves. By this automatic irrigation system watering plants at exact time based on soil © 2017, IRJET

and minerals from soil when plants needed. The current work aims to sensor network based low cost soil moisture, temperature monitoring system to track the soil moisture and temperature in real time and there by allow water given to plants based on conditions of soil moisture, temperature and type of crop grown in soil. The sensors take the inputs like moisture, temperature and provide these inputs to the microcontroller. The microcontroller converts these inputs into its desired form with the program that is running on it and gives outputs in the mode of regulation of water flow according to the present input conditions. The sensors take the inputs like moisture, temperature and provide these inputs to the micro controller. The microcontroller converts these inputs into its desired form with the program that is running on it and gives outputs in the mode of regulation of water flow according to the present input conditions. There is also a rain sensor, so whenever this sensor detects the rain then also the motor will be off irrespective of soil condition. The temperature and dangerous CO gas is also verified using different sensors which are interfaced to the controller. In case, critical situation detected through these sensors then a SMS is sent to the owner. An electrical fence is also included to keep the strangers away from the field by it’s slight shock. Presence of a person is detected through PIR sensor and then led indication with buzzer alert will be given in case of unauthorized person’s appearance. Authorized person’s presence is identified using RFID module interfaced to the controller since the RFID card is being carried by that candidate, in this case electric fence will be deactivated hence doesn’t produce any shock.
2. Existing System This system implemented by using LPC2148, soil moisture sensor, motor pump, triac combination with MOC 3021 based opto isolator which drives motor, temperature sensor, LDR sensor. A motor will turn ON /OFF based on soil condition and the temperature increases in the field. The status of motor can be showed on16X2 LCD. To find the day and night mode we used LDR sensor, Triac with bulb. The status of LDR can be showed on LCD.
