Digital display shows tire temperature, tire pressure, and time, with realtime monitoring of tire condition. An alarm flashing light signals abnormalities, helping to extend tire life, improve riding safety, and reduce energy consumption. Startstop mode for energy efficiency. When the vehicle is stationary for about 10 minutes, the unit automatically enters sleep standby. When it experiences vibrations, it automatically returns to the working state. The driving state display screen remains on, so no manual operation is needed, saving energy. Intelligent chip provides quick and accurate data processing. It can rapidly alarm when tire pressure is abnormal, with low interference, low power consumption, and a long service life. Waterproof and dustproof for reliable use in rainy weather. Charging design is convenient and supports long service life. Use scenarios Daily commuting and city driving: Continuous realtime monitoring of tire temperature and pressure helps detect issues early, supporting safer everyday driving and potentially reducing tire wear. Long road trips and adverse weather: Waterproof and dustproof construction ensures reliable operation in rain and challenging conditions, while instant alerts help you address tire problems before they become critical. Vehicle idle or parked periods: Auto sleep standby after about 10 minutes of inactivity conserves battery, and automatic wake on vibration ensures the display is ready when you start moving again.
