T. Vigneshwaran started Sri Nandha Infotech in Coimbatore to help farmers skip weeks of slow, expensive soil tests. Early efforts were technical and costly, and many agricultural experts hesitated to trust new methods. Vigneshwaran and his team created a rapid soil health device using IoT and AI that could deliver results in just 10 minutes. As farmers saw immediate improvements in crop decisions, adoption soared. The turning point came when word spread across villages, improving yields and confidence. His journey teaches that solving real field problems with practical tech can transform traditional industries.
