This document discusses using IoT technology to monitor farm fields. It reviews several existing research papers on IoT-based farm monitoring systems that use sensors to measure soil moisture, temperature, humidity and other factors. However, many of these systems have limitations such as high costs, lack of scalability, and sensors that cannot withstand harsh agricultural field conditions. The document proposes a new IoT farm monitoring system with sensors connected to a microcontroller and cloud platform. This would allow farmers to monitor field conditions remotely using a mobile app or LCD display and receive notifications. The system aims to help farmers increase crop yields while reducing water waste and crop losses.
