2.2 Sensor Description
The Tuson TPMS Retrofit Kit sensors are automotive-grade sensors
designed to monitor tire pressure and temperature consistently and
wirelessly transmit data to the receiver. Each sensor has a unique ID# to
identify the sensor to the receiver. These are internal sensors that are
securely mounted to the valve stem or using a band and bracket kit (not
included) inside the tire to prevent damage and/or theft. Internal sensors
provide more accurate pressure and temperature readings than external
sensors. The sensors are motion-activated and will go into sleep mode
when the wheels stop moving to preserve sensor battery life. Sensors
may take a few minutes to wake-up. Once the wheel speed is over 12
mph/20 kph, then the sensor will wake-up and will continue transmitting
messages to the receiver every minute while moving. As a general
reference, the sensor battery life is about 5 years when driven 4 hours
per day. See section “4. TPMS Sensors Installation” on how to install
the sensors.
