From Wikipedia
A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. As a form of vehicle telematics, a TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
