Overview of a range of novel automotive sensors
This paper presents a summary of a range of sensors developed at Sira Ltd which may be put to automotive use. The following sensors, as developed for various companies, are discussed: A range of low cost steering wheel position sensors which offer resolutions better than 0.5 degrees; An optical fuel flow sensor that detects light scattered by particles moving along with the fuel; A highly accurate electromechanical road tanker liquid level sensor and its' derivatives including a low cost sensor for use in car petrol tanks; A "Dim Dip" which optically detects an oncoming car or the tail lights of a preceding car and automatically dips the car's main beam; and, An optical linear displacement sensor, which uses widely available optical components. Possible applications include suspension arm extension, and wheel to road measurements.
