DETROIT – Nearly a year after a U.S. court ruling ran legislation requiring automotive tire pressure monitors off the road, companies making the sensors are still staying the course. SensoNor is gearing up for production launch in the U.S. market of MEMS-based tire pressure sensors tweaked to reduce cost.


The sensor, known as the SP30, is placed inside a tire in a so-called tire pressure monitoring system, or TPMS. A low-end TPMS tells drivers if a tire is under-inflated. A high-end system provides detailed information such as the pressure and temperature of each tire.

SensoNors new SP30, known as a masked version, has its programming hard-wired into the device, whereas the previous version was programmed after manufacturing.
