Features: Equipped with high performances sensors, real-time synchronization of tire pressure and temperature data for all four tires. Addressing the issue of traditional monitoring delays, early warning of abnormal tire pressure (such as air leaks and high temperatures), and avoiding the risk of tire blowouts, especially suitable for high-speed driving and long-distance self driving scenarios. More precise, accurate monitoring, timely alarm, not delay for 6 types of abnormal problems, sensor detection of data only takes 0.3 seconds. Combining appearance and interior, the pressure and temperature of the four tires, front, rear, left, and right, can be sensed and transmitted simultaneously, and displayed clearly on the screen, allowing for real-time monitoring of all wheel data and a clear understanding of various conditions. 2 in 1 charging method, both charging methods provide long-lasting battery life without stopping. Suitable for sedans SUVMPV 99% of vehicle models, including light trucks, support original factory protocol matching; The sensor is installed with a universal valves and can be disassembled and assembled in 3 minutes without tool; Specifications: Material:ABC+PC Working voltage: 3.7V Working temperature: -20C -70C Waterproof : Yes Pressure range: 0~5Bar Transmission frequency: 433.92MHz Transmission power>10dBm Charging voltage: DC5.1V Alarm Type:Buzzer, Voice Sensor Type:External, Internal Note: Please allow 1mm errors due to manual measurement.
