This document describes a smart agricultural system that uses sensors to automatically irrigate plants. Soil moisture and temperature/humidity sensors provide data to a microcontroller, which sends alerts to an Android device via Bluetooth if the soil is dry or temperature/humidity levels fluctuate. This smart irrigation system aims to efficiently use water resources, boost crop cultivation, and increase agricultural income in India by automating irrigation based on real-time sensor readings rather than a fixed schedule. It provides remote monitoring and control of irrigation via a mobile app to help farmers maximize yields.
