Short Description TPMS (Tire-Pressure Monitoring System), more specifically Direct TPMS (dTPMS), is a system that uses pressure sensors to monitor tire pressure on vehicles.

Audio Sample
TPMS (Tire-Pressure Monitoring System), more specifically Direct TPMS (dTPMS), is a system that uses pressure sensors to monitor tire pressure on vehicles. This is the RFRadio Frequency signal that is transmitted from wireless TPMS pressure sensor variants of TPMS, as there are mechanical, electrical, and magnetic variants which do not employ RFRadio Frequency transmission of data to the car. Each tire outfitted with this system contains a pressure sensor that may also monitor temperature. Data is constantly being fed from the sensors to the car's receiver.

Characteristics[edit]

TPMS occupies about 100 kHzKiloHertz (kHz) 10^3 Hz from the primary sidebands, and employs FSKFrequency-Shift Keying.
