Silchar-based engineer develops touch-free hand sanitizer dispenser


SILCHAR, JULY 19: The unabated spread of COVID-19 has called for social distancing among people with the growing need for chores that involve touchless surface contacts.

Keep this in view, Nirupam Choudhury, an engineer from Silchar, has come up with a sensor-based touch-free hand sanitizer dispenser.

Talking to The Assam Tribune, Choudhury said, "the portable touch-free 1,800 ml sanitizer dispenser machine is based on infrared motion dispenser.

"The circuit uses 5v power supply under 1A which can be delivered by a mobile phone charging adapter. Anyone keeping his palm under the dispensing machine the onboard sensors will immediately sense the obstruction and start spraying certain amount of sanitizer liquid in the palm for a pre-set time. A window on the back side of the unit shows the level of sanitizer left in dispenser. The refilling can be done using any water based alcohol sanitizer in the tank."

Choudhury, who has made at least 25 such sanitizer dispensers so far, said that the portable sanitizer dispenser can be used at indoor locations in hospitals, hotels and restaurants, offices and educational institutions.
