IoT BASED SMART IRRIGATION FOR AGRICULTURAL FIELDS USING SENSORS AND NODE MCU ESP8266 WI-FI MODULE

India is the second-largest irrigated country, but only one-third of the area is irrigated. It is due to uncertain rainfall and lack of water. Most of the areas need canals to be built for irrigation without being depending on the rainfall. The utilization of water is very important for irrigation. The implementation of IoT agriculture starts with intelligent irrigation for the majority of fields. Optimizing the water schedule and quantity of water helps us to save water, money, and have the best crop on the field. Sensor-based IoT technology gathers soil moisture, temperature, humidity data, and transmits this information to farm irrigation systems from sensors. A platform responds to these signals and the drip irrigation switches on as soon as there is insufficient water in the soil. Our research is designed to overcome the problem of irrigation by reducing the usage of water while watering the plants. The proposed system uses sensors like a temperature and humidity sensor. The microcontroller is used to send data to web server is used to monitor the data, and web server is used to store the data. This system provides a feasible monitoring platform and automates the irrigation process. This leads to a transition from traditional farming to modern farming. Over 74 years since independence, India has made immense progress towards agriculture. In our system, we will use Node MCU ESP8266, DHT11, IoT based devices, open source Arduino Software and web server for implementation of proposed technique.
