Agriculture is important as well as it provides us with food for livestock and for humans to eat and prosper with. Farmers deal with issues on a daily bases as over-irrigation and under-irrigation can demean the quality of crops on the short and long range. Therefore, continuous and precise monitoring is required to ensure maximum agricultural yield. With increase in the population the demand for water also increases concurrently. The population in India is expected to increase 2 times the present by 2050. IoT referred to as Internet of Things proposes an innovative approach to quality of agriculture. Using IoT, we built a smart irrigation system using LoRA technology. This work proposes a solution that has both a conceptualized and actualized prototype of a smart irrigation system that uses an IoT approach for monitoring the fields and controlling water motors to ensure coverage of large fields. Moreover, this work proposes a control over web application with a micro- controller hosting webserver with a two factor authentication over mobile SMS, and saving data over online database. In particular, this work proposes connection using long range communication between nodes to monitor sensor data, with manual or automatic control over irrigation based on sensor thresholds.
