T10W Automotive-Grade External BLE Tire Pressure Sensor For Trucks

Bluetooth External Automotive-Grade Commercial Vehicle Tire Pressure Sensor—Product Overview

The Bluetooth External Automotive-Grade Commercial Vehicle Tire Pressure Sensor is a BLE (Bluetooth Low Energy) communication-based, non-invasive, external, automotive-grade, high-precision tire pressure monitoring device designed for all types of commercial vehicles. It fully complies with the JT/T 1429 industry standard for commercial vehicles and is specifically developed for heavy-duty trucks, light-duty trucks, buses, engineering vehicles, trailer RVs, and other heavy-load, high-frequency operation vehicles. Unlike traditional RF (radio frequency) sensors, this product employs a next-generation Bluetooth 5.0 low-energy communication solution. It eliminates the need for complex RF reception hardware and relies on Bluetooth wireless transmission to exchange tire data. With its external valve stem mounting design, it requires no tire removal, no wheel balancing, and causes no damage to the vehicle’s original structure.

The sensor integrates an automotive-grade MEMS sensor chip, an acceleration-activated wake-up module, and a high-precision temperature measurement unit. It accurately collects real-time data on tire pressure, tire temperature, and battery voltage, supports parallel network monitoring across multiple wheel positions, and is perfectly suited for the extreme operating conditions of commercial vehicles, including heavy loads, rough terrain, prolonged high-speed driving, and environments with mud, sand, rain, and extreme temperatures. It can interface with in-vehicle terminals, mobile apps, and smart fleet management platforms, addressing the pain points of traditional commercial vehicle tire pressure monitoring systems—such as significant signal interference, complex networking, poor scalability, and cumbersome operation and maintenance—while balancing vehicle operational compliance, driving safety, and smart fleet management requirements.

II. System Composition

The entire Bluetooth TPMS system features a minimalist architecture, high integration, and strong scalability. Centered around an external Bluetooth sensor—which eliminates the need for a separate RF receiver—it is designed to accommodate commercial vehicle scenarios involving multiple wheel positions, long vehicle bodies, and multiple trailers. The core components are as follows:

1. Bluetooth External Automotive-Grade TPMS Sensor (Core Component): Features a high-strength alloy housing designed specifically for commercial vehicles and a corrosion-resistant brass valve stem, paired with an anti-theft locking nut and anti-loosening washers to prevent vibration-induced detachment and unauthorized removal. It incorporates an automotive-grade pressure/temperature sensor chip, a three-axis accelerometer, a BLE Bluetooth communication module, and an ultra-low-power battery management unit. Supporting high-pressure range monitoring for commercial vehicles, it features IP68-rated dust and water resistance and withstands harsh operating conditions such as salt spray, mud and water, intense sunlight, and high temperatures generated by braking. It serves as the data acquisition core of the entire system.
2. Bluetooth In-Vehicle Terminal/Host: Replacing traditional RF receivers, it supports automatic Bluetooth signal scanning and multi-device networking and pairing. It can stably receive Bluetooth data from multiple sensors across the entire vehicle and trailer, is resistant to electromagnetic interference from onboard electronic control systems and the alternator, and is compatible with the 24V voltage of commercial vehicles. It is responsible for data aggregation, parsing, and preprocessing.
3. Visualization Terminal: Compatible with in-vehicle central control screens, dedicated TPMS high-definition displays, and mobile apps, it displays tire pressure, tire temperature, and sensor battery level data independently for each wheel. It offers high-definition visibility day and night, features simple operation, and is optimized for commercial vehicle cab environments.
4. Cloud-Based Fleet Management Platform: Connects to the internet via the in-vehicle terminal to upload Bluetooth sensor data, enabling remote tire condition monitoring, push notifications for anomalies, data statistics and analysis, and fault tracing. Designed to support centralized and intelligent fleet operation and maintenance management models.
5. Intelligent Early Warning Control Module: Equipped with algorithms specifically designed for commercial vehicles, this module handles operating condition adaptation, intelligent threshold determination, and fault classification and early warning. It supports system self-diagnosis and fault log retention, ensuring accurate and stable monitoring across multiple wheel positions.

III. Core Features

1. Real-Time, Precise, Full-Range Bluetooth Monitoring: Based on BLE (Bluetooth Low Energy) 5.0 communication, it supports flexible networking for 2–12 wheel positions, covering tire monitoring for the entire vehicle, including the tractor unit and multiple trailer sections. The system automatically wakes up while driving and enters sleep mode when parked, collecting real-time tire pressure, tire temperature, and battery voltage data under all operating conditions. Measurement accuracy meets automotive standards, and data transmission is stable with no lag or packet loss.
2. Multi-Dimensional Intelligent Tiered Alerts: Tailored for heavy-duty commercial vehicle operating conditions, it supports eight major alert functions: under-inflation, over-inflation, high-temperature warnings, rapid air loss at high speeds, slow air leaks, low sensor battery, Bluetooth signal loss, and device malfunction. The alert logic is optimized for high-frequency risks specific to commercial vehicles—such as sudden tire temperature spikes during continuous braking and hidden air leaks under heavy loads—ensuring rapid response and precise filtering of false alarms.
3. Quick, Non-Dismount, Non-Destructive Installation: Purely external installation requires no tire removal or modifications to the tires or the vehicle’s original wiring; a single person can quickly install and configure the system. It supports one-click automatic Bluetooth pairing and adaptive wheel position recognition. After tire rotation or sensor replacement, re-configuration can be completed quickly without specialized equipment, significantly reducing maintenance labor hours.
4. Ultra-Low Power Consumption and Long Battery Life: Equipped with a dual-mode system featuring smart motion wake-up and deep sleep modes—the sensors operate only when the vehicle is in motion and enter ultra-low-power standby when stationary. Combined with an automotive-grade long-life battery, the sensors have a service life of 3–5 years, making them ideal for commercial vehicles’ high-frequency operations and long-term working conditions while reducing the frequency of battery replacements.
5. Strong Interference Resistance and Stable Networking: Bluetooth communication offers far superior resistance to electromagnetic interference compared to traditional RF solutions, effectively mitigating signal interference from commercial vehicle generators, electronic control systems, and onboard electrical equipment. Networking remains stable even with long vehicle bodies, multiple trailers, and complex road conditions, eliminating signal disconnections and data delays.
6. Multi-Device Integration and Data Traceability: Supports real-time data synchronization across three platforms—in-vehicle displays, mobile apps, and cloud platforms—allowing for real-time monitoring of tire operating status. It automatically stores fault data and alert records, enabling traceability of potential hazards and data analysis to support preventive maintenance.
