Hyundai Kona: Tire Pressure Monitoring System / TPMS Sensor Description and operation
| Description |
| 1. |
General description
WU is a sensor placed in the tire that reports pressure and temperature.
The WU is mounted inside the wheels, fixed to the valve. The angle between
the valve and the housing of the WU is variable.
This allows adaptation to various types of rims.
The Wheel Unit is made of a PCB supporting the electronic hardware and
encapsulated inside a housing which is potted with polyurethane.
It is self-powered by a battery and includes all systems for parameter
measurement (pressure, temperature and centrifugal acceleration and
optionally rotation direction), RF transmission and LF detection.
To achieve the specified battery lifetime, the WU supports various measurement
and transmission timings, depending on WU operation mode.
For RF transmission, WU uses an internal antenna.
