La description

TPMS stands for Tire Pressure Monitoring System, which is an auxiliary system installed on car tires to monitor tire pressure in real time. The tire pressure monitoring system, airbags, and ABS systems constitute three major safety systems for automobiles. It installs a transmitter containing a high-sensitivity temperature sensor and pressure sensor chip on each wheel, and monitors the temperature and pressure of the tire in real time in the driving or stationary state, and transmits it to the controller by radio frequency. When the tire leaks or the air pressure is low, the alarm will be issued to ensure the driving safety.
 

Shengrun Technology PCBA Solution for Tire Pressure Monitoring

The built-in tire pressure sensor is placed inside the tire, and the position of the valve has the advantages: the tire pressure display is very accurate, and the sensor is hidden inside the tire, without experiencing wind and rain, good safety and long life. No changes can be seen from outside, inflation is not affected, and it can be charged inflation anytime and anywhere. Disadvantages: Installation is troublesome and you cannot operate it yourself, because you need to separate the tire from the wheel to install it, and you need to go to a repair shop. If the four-round transposition operation is performed, the tire pressure monitoring needs to be re-learned for pairing. Otherwise, the display will not be able to distinguish which round, or it will display the original position.
