General Description

【Wheel Electronic (WE) sensor unit】- TPMS sensor
Each vehicle wheel is fitted with a Wheel Electronic (WE) sensor unit attached to the valve on the inside of the wheel.
The WE unit is powered with a self-contained battery utilizing a high temperature rated CR (Manganese Dioxide
Lithium) chemistry. The operating voltage range for the WE module is 1.8Vdc to 3.6Vdc, and the operating temperature
range is -40°C ~120°C. The WE measures tire pressure, temperature, and acceleration periodically. The pressure,
temperature, and acceleration information is converted to digital form within the MCU inside the WE sensor.
The WE sensor is equipped with a Radio Frequency (RF) transmitter circuit which is used to periodically broadcast
