Background/Objectives: This paper presents an automatic irrigation system to provide water to the farms based on soil and temperature conditions. It can also control irrigation system through the web application and GSM by using Raspberry pi 2 and 8051 microcontroller. Methods/Statical Analysis: Number of sensor nodes will be placed on farm according to the area of the farm, each sensor node contains temperature sensor, moisture sensor, water level sensor and motor. 8051 microcontroller makes the communication with all sensors placed in the farm and it can collect the parameters like moisture, temperature and water level. Raspberry pi 2 is used to control the web application and GSM modem. Raspberry pi 2 takes data from 8051 microcontroller continuously using a wireless communication device. In this paper ZigBee transceiver is used as a wireless device for transmitting and receiving data from both devices. A threshold value is given for each sensor, if any sensor crosses its threshold value a message will be send to the user and display in web applications. Findings: This system uses Raspberry pi 2 for achieving high speed of operation. In real time farms which are remote areas, this system uses 8051 controller for collecting data from sensors and transfer it to Raspberry pi 2 using wireless sensor device. This system controls the motor automatically when soil or temperature crosses its threshold and manually whenever user wants. Conclusion: This irrigation system works efficiently and speeds. This system sends message to the users whenever sensors exceed its threshold value. This system offers every user to understand the soil conditions and amenable manually.
