1Dynamically monitor the tire pressure of 4 wheels at the same time to prevent tire blowouts, improve fuel efficiency, extend tire life, and ensure driving safety. 2It is designed as a direct tire pressure monitoring system by installing pressure and temperature sensors on the tires and displaying data in real time on the mobile phone (for Android for IOS) via Bluetooth connection. 3During driving, tire pressure and temperature are displayed in real time, and an alarm is issued when statistics are abnormal. Supports for Android and for iOS, Bluetooth 5.0 or higher is required. 4The 4 sensors adopt waterproof, anticorrosion, and antitheft technologies, which are fully capable of rainy weather and are suitable for outdoor use. 5Using superior chip, high sensitivity and high stability, high accuracy of measuring pressure and temperature. The battery life is as long as 35 years, and it is easy to replace. 6It can help you save up to 11 cents of fuel per gallon when inflated correctly. And you can maintain the car tires yourself, without having to go to the car dealer.

Open the application by scanning the QR code link. Scan the QR code card with the words One-Key Binding or scan the corresponding sensor ID code to complete the link.2. Install and wait for the application to open. Install the sensors on the corresponding tires according to the sensor markings until the installation on each sensor is completed.Note: If the sensor data cannot be obtained, please reinstall the sensor (install slowly so that the air pressure is in full contact with the sensor) 4 x Tire Pressure Sensors4 x Screws1 x Wrench1 x Manual 1. Support cellphone with Bluetooth 5.0 or above. Do NOT support Cellphone with Bluetooth lower than 5.0. 2. Product displays by cellphone. During driving, please be careful when viewing tire pressure and temperature in cellphone. If tire pressure accelerates down or up continuously, please stop car and check if there's any problem with the tire.3.This product can read tire pressure and temperature, but it cannot avoid sudden accident caused by tire. It's important to use tire with high quality. Slightly tire leakage makes tire pressure decreases over time is normal. It has nothing to do with this product installation.
