The paper describes the smart irrigation system using the concept of IoT. The project uses a Wi-Fi module (ESP8266-12) which connects the system to internet. This module controls a motor and two solenoid valves for supplying water to the field on the information obtained from a water level indicator and two soil moisture sensors. This whole system is monitored and controlled by MQTT server (My MQTT android App) through internet. The paper also depicts the concept of Internet of Things (IoT).
