Smart Irrigation System using IoT

A Smart Irrigation System uses technology to help farmers save water and reduce manual work. It relies on an ESP32 microcontroller and sensors for soil moisture, rain, temperature, and humidity. When the soil is too dry and there’s no rain, the system starts the water pump through a relay. Farmers can see real time sensor readings on a small OLED display and track data remotely on Thing Speak using Wi‑Fi. Powered by solar panels and a rechargeable battery, this system runs off‑grid a green and cost‑effective choice for rural areas. IoT based irrigation systems like this typically save 30% to 50% of water compared to traditional methods while also boosting crop health and yields. Remote monitoring means farmers can adjust watering from a phone or computer Data driven decisions reduce human errors and help plan irrigation better. Testing shows the system effectively cuts water use and minimizes manual labor, making it ideal for small to medium farms. In the future, adding multi‑zone support, mobile alerts, and smarter controls like weather based automation could make it even more efficient and powerful.
