What is tpms?

A typical TPMS (Tyre Pressure Monitoring System) monitors the air pressure in the tyres with a wheel mounted sensor(Either externally or internally mounted). This type of TPMS can detect actual pressure levels and transmit constant information to the driver via a receiver inside the vehicle. Tyres are monitored individually by sensors attached to a special tire valve of each wheel. Each sensor monitors and transmits tyre pressure and temperature(model dependant) every few seconds while vehicle is in motion. The temperature is monitored to compensate for cold and warm pressure variations. In order to reduce battery consumption, the sensors revert to a "sleep" mode when the vehicle is parked or not moving.
