Sensors in the Automotive Industry

The average car on the road today is fitted with a variety of sensors monitoring a whole host of elements from engine speed and mass air flow to parking sensors. In fact, the standard on board diagnostic interface on most modern-day automotive vehicles will normally contain more than 50 individual sensors.

This has been largely driven by the relentless pursuit of increased safety, improved reliability, enhanced energy efficiency and reduced environmental impact that manufacturers are continually striving towards.

With these key areas becoming more and more important in modern day cars and more demanding requirements being placed upon the machines. Being able to respond to changing conditions, by monitoring and responding to data is a must. As a result, sensor technology has become an integral part of automotive vehicle design and manufacturing.
