Tyre pressure monitoring (TPMS)
A tyre pressure monitoring system (TPMS) puts a sensor in each wheel that measures pressure and temperature and transmits them wirelessly to a display or the vehicle network. DWIN builds TPMS sensors, complete systems and solar-powered aftermarket kits.

How it works
A MEMS pressure sensor, a temperature sensor, a microcontroller and an RF transmitter sit inside each wheel, powered by a long-life battery. The sensor wakes on motion, samples pressure and temperature, and transmits at a set interval, faster when pressure drops quickly.
How to choose
- Mounting: valve-stem external caps or internal sensors
- Display: dashboard receiver, solar display, or integration with the vehicle head unit
- Vehicle type: passenger car, truck or two-wheeler pressure range
- Radio frequency approved in your market
Frequently asked questions
Is TPMS required by law?
Many markets require TPMS on new passenger cars, including the United States, the European Union and China. Aftermarket kits add the same warning to vehicles built without it.
How long does a TPMS sensor battery last?
TPMS sensors sleep between transmissions, so a sensor battery typically lasts several years. Battery life depends on transmission interval, temperature and how much the vehicle is driven.
