Internal TPMS Ball Sensor (TPMS-BALLSENS)

The Tuson TPMS Ball Sensors are automotive-grade internal 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 freely bouncing 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. Sold individually.
