A small device conceived and developed by a Class VII boy of a school in Chinsurah can help curb pollution caused by emission from vehicles.

Avigyan Kishore Das, 13, of Hooghly Collegiate School, was adjudged first in a contest organised at the India International Science Festival (IISF) 2019 in Calcutta on Thursday.

Avigyan’s device when fitted to a vehicle’s engine can disable its movement permanently once its emission goes beyond the permissible level and its owner does not rectify it despite a third SMS reminder sent to the person’s cellphone.

Researches have shown that more than half of carbon monoxide and nitrogen oxide and almost a quarter of the hydrocarbons present in air are from vehicular emissions.

Avigyan has sent details of the device — called “Safety and alert for excessive pollution” — to the National Innovation Foundation for examining its feasibility. He has also applied for a patent.

The budding talent displayed his device at the Biswa Bangla Convention Centre before a large number of scientists and technologists.

It was ranked the best out of the 30 entries from across India in the category titled “Building self-sustainable smart Indian cities: Ideas and approaches”. Avigyan was awarded a cash prize of Rs 30,000, a citation and a memento at the concluding ceremony of the IIFS on Thursday night.

The competition was part of the IISF organised jointly by the Union ministry of science & technology, ministry of earth science and health and ministry of family welfare for `Nav Bharat Nirman’.

Speaking to The Telegraph, Avigyan said: “My idea was not just to curb pollution but to bring it down to zero by conceiving such a de- Avigyan Kishore Das being presented with the first prize in Calcutta on Thursday; (below) Avigyan displays the device vice that can stop the movement of a polluting vehicle as errant owners often violate green norms in the absence of any strong legal actionTo build his device Avigyan has used a sensor (MQ7) that can sense carbon monoxide and hydrocarbon as well.

“Whenever the vehicle’s pollution level crosses the permissible limit, it will alert the owner/driver by blinking a LED light and sending a text message,” said Avigyan, whose father is an audit officer with the CAG.

“As alerting the owner is not enough, I have added a feature to my device so that none can go on polluting,” he said.
