Descriptions: Tire Pressure Monitoring System is mainly used for real-time monitoring and alarming of information such as low tire pressure, high tire pressure, rapid air leakage, high tire temperature and low battery voltage during car driving. The driver's effective information to maintain sufficient tire pressure, prevent the occurrence of puncture accidents, increase the safety of driving the car, reduce the extra oil generated by the tire tire pressure, and extend the life of the tire. The direct tire pressure monitoring system is equipped with a high-sensitivity sensor in each tire, which can monitor the pressure and temperature of the tire in real time. After digital-to-analog conversion, the data is transmitted by radio signals to the display mounted on the bridge. Values and temperature values are displayed visually immediately. If the tire pressure is too high or too low during driving, the tire will leak due to any reason (such as foreign matter piercing the tire, tire scratching...), and the system will automatically alarm immediately to ensure safe driving. The TPMS wireless tire pressure monitor uses the world's top line sensor chipset and has multiple wireless communication technologies, eliminating the need for additional repeaters. When the car is driving at high speed, the signal reception is accurate and can reflect the tire pressure condition most realistically and intuitively. It is currently advanced in technology and stable in performance.
