External Valve Stem Mounted BLE TPMS Sensor with Replaceable CR1632 Lithium Battery for Passenger Cars

Product Overview

C15W is a BLE external TPMS sensor developed for passenger cars, SUVs and MPVs. It adopts external valve cap mounting design, no tire disassembly or wheel balancing required during installation. The sensor monitors real-time tire pressure and temperature, and transmits data via BLE Bluetooth to display terminal or mobile APP. It provides early warning of low pressure, high pressure, overheating and rapid air leakage to prevent blowouts during daily driving. Featuring compact size and easy installation, it is an ideal aftermarket TPMS upgrade solution for private cars and passenger vehicle fleets.

System Composition

The complete TPMS monitoring system includes three core components:

• C15W External BLE TPMS Sensor: Screws onto tire valve stem, integrates pressure sensor, temperature sensor, BLE module and low-power MCU to collect and wirelessly send tire data.
• Receiving Terminal: Supports dedicated TPMS display, BLE gateway and vehicle host for data reception, real-time display and audible & visual alarm.
• Mobile APP Terminal (Optional): Connect via Bluetooth to view tire status, historical records and alarm logs.
