A smart irrigation system using IoT helps farmers and gardeners water their crops based on real-time data. It uses sensors to monitor soil moisture, weather, and temperature. The system sends this data to a central device, which decides when and how much to water. This avoids overwatering or underwatering. It saves water, boosts crop health, and reduces manual work. visit: https://www.karikala.in/blog/smart-irrigation-system-using-iot/
