Tyre Pressure Monitoring Systems (TPMS) are electronic safety devices designed to monitor the air pressure and temperature of pneumatic tires on various vehicles
Technical Specifications :
- Pressure Range: Most passenger vehicle systems operate between 0 and 100 psi (07 bar). Industrial or heavy-duty systems (LCV/Trucks) can monitor up to 116190 psi.
- Operating Frequencies:
- 315 MHz: Standard for North America and parts of Asia.
- 433.92 MHz: Common in Europe and universal aftermarket kits.
- 2.4 GHz: Modern battery-less transponder systems use this range to reduce interference.
- Communication Protocols: Data is typically transmitted via Bluetooth Low Energy (BLE) for smartphone-connected devices or Radio Frequency (RF) using Frequency Shift Keying (FSK) modulation for dashboard displays.
- Temperature Range: Sensors are rated for extreme environments, typically from -40C to +125C.
- Accuracy: High-precision sensors generally offer an accuracy of 1 psi and 1C
