Implementation of Internet-of Things (IoT) in Soil Irrigation System

Solutions to issues faced in the conventional soil irrigation system have been obtained by integrating Internet of Things (IoT) technology. A prototype IoT device is designed to monitor and control water supply to the plants using a Node MCU, microcontroller, moisture, temperature, humidity, and rainfall sensors. The wireless sensor network system has been applied to transfer the data and control water supply to the soil irrigation system. The analogue signals received from sensors have been processed by the microcontroller unit based on the user's requirements. The ‘C’ language is used to make the microcontroller code based on the logical aspects. The Blynk software application has been used to analyze the MCU data and convey the information about temperature, rainfall, amount of water, and humidity of the soil to the user through an e-mail alert. An IoT system can be used to minimize water wastage and minimize the overall cost of the soil irrigation system.
