Reed Switches in Exhaust Emissions Sensing
Pollution, greenhouse gases and smog play a large role in global warming and it is most important to ensure that automobile emissions are monitored conscientiously by manufacturers. These polluting gases which make up most of emission levels in automobiles are reduced by catalytic converters which convert them into less harmful gases by catalyzing an oxidation and reduction reaction. A simple vane with a magnet fitted inside the tailpipe of automobiles is used to trigger a reed switch which provides feedback after using data from other sensors such as Oxygen sensors to the CPU, to adjust fuel mix ratio thereby reducing emission levels.
