Principles of Motion Sensing. Sensors able to detect three-dimensional motion have been commercially available for several decades and have been used in automobiles, aircraft and ships. However, initial size, power consumption and price had prevented their mass adoption in consumer electronics. While there are other kinds of motion detector technologies available commercially, there are four principle types of motion sensors which are important for motion processing in the consumer electronics market.
Direct TPMS uses a sensor mounted in the wheel to measure air pressure in each tire. When air pressure drops 25% below the manufacturerâs recommended level, the sensor transmits that information to your carâs computer system and triggers your dashboard indicator light. Indirect TPMS works with your carâs Antilock Braking Systemâs (ABS) wheel speed sensors. If a tireâs pressure is low, it will roll at a different wheel speed than the other tires. This information is detected by your carâs computer system, which triggers the dashboard indicator light.
