With an aim to help the doctors, hospital staff members, media personnel and government officials in maintaining a proper sanitation practice, the ICAR-Central Institute of Post-Harvest Engineering and Technology, Ludhiana, Punjab has designed a sensor-based Touch-free Dispenser of the Hand Sanitizer. The device has been developed to promote the practice of hand-sanitization for containing the spread of the deadliest COVID-19 infection.
The smart device works on the principle of automatic obstacle detection with Infra-red proximity sensor and programmable micro-controller. The device dispenses the alcohol-based hand rub sanitizer from a 3.0 litre tank using a small, yet powerful diaphragm pump. The software controls the dispensing volume of about 3 ml in one go; which can be further increased or decreased volumetrically, by changing the programme in the software. The instant dispense of the sanitizer is possible once the proximity sensor senses the presence of hindrance by hands. The user can collect the dispensed volume of liquid from the device in the cupped hand.
The efficient and touch-free mechanism reduces the infection’s risk at use in public places and ensures right volume as per the requirement of the user for hand sanitation purpose. The device operates on 12V DC electric power supply. The prototype is built on a small stainless steel 316 encasing the electronics circuit. This small and smart device can play a vital role in reducing the infection’s risk. The device has been developed by Er. Yogesh Kalnar and Dr. Rahul K. Anurag, Scientists under the guidance of Dr. R.K. Singh, Director, ICAR-CIPHET, Ludhiana. Punjab.
