The Internet of Things (IoT) has revolutionized every element of the typical person's everyday existence by making everything intelligent and smart. In order to monitor and regulate the field's environment in real time, this study sug- gests an Internet of Things (IoT)-based smart irrigation system that makes use of cloud computing, a variety of sensors, and a microcontroller. The system aims to reduce the time and energy of farmers by automating the process of monitoring field conditions and show the real-time measurement on mobile application and web application. To enable automation using IoT devices, the gathered data is processed and kept on the cloud. Temperature (DHT-11), humidity (DHT-11), soil moisture, water pump, fertilizer management (pH meter), and raindrop monitor are among the experiment's out- comes. The technology interacts with farmers to conduct decision-making analysis, and it has the ability to boost crop output and cut down on resource waste in the ag- riculture industry.
