The IoT-based smart irrigation system is an innovative approach to water conservation and agriculture management. This system employs the Internet of Things (IoT) technology and uses sensors, microcontrollers, and wireless communication to automate the irrigation process. The system continuously monitors soil moisture level and determines & supplies the optimum amount of water required for the crops using a pumping motor connected to the farm. This system can help farmers save water, reduce energy costs, and improve crop yields. The system can also be remotely monitored using the Thingspeak IoT platform.
