An Automatic Irrigation System using WIFI in Wireless Sensor Network

Abstract: The project is designed to develop an automatic irrigation system that switches a pump motor ON/OFF by sensing the moisture content of the soil using wireless technology effectively for agriculture applications through wifi module used in sending an SMS on the status. In the field of agriculture, use of proper method of irrigation is important. The advantage of using this method is to reduce human intervention and to ensure proper irrigation. The project uses ESP8266 MOD which is programmed to receive the input signal of varying moisture condition of the soil through sensing arrangement. Once the module receives this signal, it generates an output that drives a relay for operating the water pump. This concept in future can be enhanced by integrating XBEE/Bluetooth technology, such that whenever the water pump switches ON/OFF, the information is sent to a smart mobile phone or XBEE transceiver module regarding the status of the pump.
