Coimbatore: The ICAR-Central Institute of Agricultural Engineering’s regional centre near Perur here has developed a touch-free hand wash system that can be installed in public places such as hospitals, offices, malls, factories and railway stations.
As the novel coronavirus spreads through contact and washing hands for 20 seconds is one of the ways to prevent it, the touch-free system will add another layer of safety, principal scientist T Senthilkumar said.
The system uses a sensor, which activates a pump to discharge soap and water when a person places hand near the tap. “We came up with the idea after the lockdown was imposed. The system was designed in 15 days. It can be operated with an AC power connection or a battery or a solar panel,” Senthilkumar, who developed the system with the help of Syed Imran, another scientist at the centre, said.
The system has a 75-litre water tank, which can also be customised. The automated set up consists of a photo diffuser sensor, which senses the presence of a hand to turn on a pump, which effects the flow of liquid soap from the dispenser and water from the tank. In a single time, up to 5ml of soap is dispensed from the dispenser and 100ml water is dispensed from the tank.
The discharge can also be regulated to avoid water wastage. “Normally, when we wash hands, we use around 300ml to 400ml water. But our automated system dispenses only 100ml of water per discharge. The cost of the system is Rs 10,000. We plan to tie-up with manufacturers,” Senthilkumar said. He can be contacted at 9842955606.
