amandasjohnston on 07 Dec 16Four mechanical engineering students from Nashik have invented a device which is an indicator for the vehicle driver about excessive pollutant levels, while driving. When the engine of the vehicle starts, the sensor fitted in the silencer will sense the exhaust particles and check the limit value. If it exceeds the prescribed limit then a red light will blink as the first indicator, for two hours. Even after the first warning, if there is no change in the limit then there are two more indicators that will blink within a gap of two hours after which the engine will automatically turn off. According to the four inventors, the device will help in tackling the pollution issue, especially in densely-populated and polluted areas.
