Main components in the package are a cigarette plug transceiver and four valve-cap external sensors (TPMS-8886)/ professional internal sensors (TPMS-85). First, install the sensors. Second, plug the transceiver into a cigarette lighter and pair with the device by Bluetooth. Then, the transceiver works automatically whenever the vehicle is ignition on and the paired device inside the vehicle. The function of this system is to provide high/low tire pressure warning, fast/slow leaking warning, high tire temperature warning, low battery sensor warning and sensor failure warning. The driver can view any individual tire data from the device any time to ensure the both tire pressure and temperatures are within the safety range. Once abnormal tire data received, the transceiver will have both audio (beep sounds) & visual (the light changed from green to red) alerts and the App will show the corresponding tire data. Features 1.Wireless transmission 2. Real-time monitoring and display. 3. Audio and visual warning 4. TPMS-8886 comes with the lightest valve-cap sensor, no balance needed after installaion 5. Converitable language, pressure unit (Bar、Psi、Kgf/cm2) and temperature unit(℃,℉.)
