A smart irrigation system using IoT helps monitor and control watering schedules based on real-time data. It uses sensors to measure soil moisture, temperature, and weather conditions, ensuring that plants get just the right amount of water. This reduces water wastage and promotes healthy plant growth. Farmers can control irrigation remotely through mobile apps or cloud platforms. By using IoT in irrigation, agriculture becomes smarter, efficient, and cost-effective. It’s a modern solution for sustainable farming.
