1、It uses lithium batteries and solar panels for charging, and has 6 external sensors. The receiver can display the time and monitor tire pressure and temperature in real time. 2、Lightweight design, easy to install sensor. With the help of RF wireless technology, the tire pressure monitoring system can automatically alarm when the tire pressure and temperature are abnormal. 3、The color LCD digital display is clear day and night, high‑precision monitoring of temperature and pressure, and simultaneous display of 6 tires. The display can be changed to 4 tires. Support tire position change function. 4、With the help of TPMS, we can keep the tires within the specified pressure and temperature range at any time, save fuel, reduce tire damage, prevent air leakage, and ensure driving safety. 5、Solar charging, no need to connect the car cigarette lighter to charge, wireless connection with the sensor, easy to install 6、With the smart shock absorber design, when the car encounters obstacles, it runs more stable and shockproof, no need to open/close.
