India’s rural population depends on agricultural activities for livelihood. While most farmers are moving ahead with technology for irrigation, small scare farmers depend on water from the borewells. A team of engineering students from the Sona College of Technology, Salem, have developed an Internet of Things (IoT) based farm-friendly system that reduces water usage and minimizes dependency on fertilizers.
Using a designated permanent rare earth magnet, the water is passed through a magnetic field and undergoes electrolysis and magnetisation. The water molecules are rearranged into hexagonal-shaped clusters, which improves water quality. Saltwater is converted into hard water, which results in better yield production.
The team consists of six students – Manimoliselvan C, Dinesh Kumar B, Manikandan S, Lokeshwar S, final-year Civil Engineering students, Kungumaswetha A, final-year Computer Science Engineering student and Suvetha S, final-year student (Electronics and Communications Engineering).
“The magnetisation process works along with the IoT system and is connected to a mobile app. The system is fitted with sensors that can measure water levels, weather, and optical transducers to monitor nutrient absorption, which allows the farmers to know about the water requirement depending on the soil type and crop. The water quality is optimised by magnetisation and lesser water is required for agricultural activities,” says Manimoliselvan C.
The project had also won the Smart India Hackathon 2020 in the hardware category. The team is also working on applying for a patent for the IoT-based solution.
A reduction in water usage, low dependency on fertilizer and pesticides and can be a boon for farmers. “The solution was developed in around six months, starting with the selection of the right magnet that can be used for borewell water at all places, visual observation on potted plants and then moving to a peanut field for research,” says R Malathy, dean (R&D) and professor, department of Civil Engineering, who was also the project supervisor.
