1Function: Tpms sensor is mainly used to monitor the temperature and pressure of automobile tires in real time. When the pressure and temperature exceed or fall below the standard value range, the system will issue an alarm signal, thereby effectively avoiding traffic accidents. 2Multi Purpose: Once the air leaks, tire pressure monitoring sensor will quickly alarm to prevent the car from deviating, prevent tire pressure from being inconsistent, prevent tire blowout, monitor tire temperature in real time, save fuel, and reduce tire wear. 3Characteristics: Tire pressure monitoring sensor has the characteristics of dustproof, cold and high temperature resistance, anti drop and anti collision, and reduces the risk of driving. 4Display Data Via Your Phone: Designed to be a direct tire pressure monitoring system by installing pressure and temperature sensors on the tires and displaying the data in real time on a mobile phone via a Bluetooth connection, support for Android and for Ios. 5IP67 Waterproof Grade: Professional manufacturing, car tire pressure monitoring sensor is waterproof, can be used in any weather conditions, can deal with harsh environment, .
