Agriculture is undergoing a major transformation. With rising input costs, climate uncertainty, water scarcity, and labour shortages, traditional farming methods alone are no longer enough to meet global food demand. This is where IoT sensors in farming are playing a critical role. The Internet of Things (IoT) enables farmers to collect real-time data from fields, crops, soil, livestock, and equipment. By using smart sensors, farmers can make data-driven decisions, increase productivity, reduce waste, and improve sustainability.
