6 External SensorsFeatures: The tire preure monitoring system (TPMS) can monitor tire preure/temperature status in real time. It will transmit real-time voice alarm and flashing warning iron to remind the driver of the comfort and driving safety of the vehicle. Simultaneous display of tire preure and temperature. Air leakage warning, low preure warning, high preure warning. High temperature warning, low power warning, no signal warning. Solar Power & USB Charging: The intelligent wirele system with 2 charging ways which ensure the tire preure monitoring system will work continuously, rechargeable lithium battery to get electricity can increase the tires life. Solar and USB charging bid farewell to traditional wiring. Suitable for 6 tires: The maximum tire preure is le than 8bar ,Real-time monitoring the temperature and preure with high degree accuracy for 6 tires simultaneously and can automatically change the corresponding data, LCD display mode ensure the high resolution ratio and guarantee the high-definition and no splash screen condition. Digital Display: The LCD screen, with bright backlight and clear data, allows you to easily and comfortably understand the state of your car. We have also equipped an adjustable bracket, which can adjust the tire preure display according to the slope of your dashboard. 6 sensors: We provide 6 sensors, suitable for use in rainy days. In addition, they have high sensitivity and high accuracy and can be used to measure preure and temperature.
