An Internet of Things (IoT) based irrigation system designed to automate water supply for agricultural fields using sensor data and embedded controllers. The system aims to optimize water usage by monitoring environmental conditions and controlling irrigation intelligently.
This project integrates an Arduino microcontroller and an ESP8266 Wi-Fi module to collect sensor data such as soil moisture, temperature, and humidity. Based on the sensed parameters, the system controls a water pump through a relay module.
The system also supports remote monitoring through an IoT platform, allowing users to observe real-time sensor data and system status.
- Sensor Layer: Soil moisture and environmental sensors
- Control Layer: Arduino microcontroller
- Communication Layer: ESP8266 Wi-Fi module
- Actuation Layer: Relay-controlled water pump

- Soil moisture sensor continuously monitors moisture level in the soil.
- If moisture drops below a predefined threshold, the Arduino activates the relay.
- The relay turns ON the water pump for irrigation.
- Environmental data (temperature & humidity) is collected via DHT sensor.
- ESP8266 transmits sensor data to the IoT dashboard for remote monitoring.
- When moisture reaches sufficient level, irrigation is stopped automatically.
