At the 40th annual Sensors Converge 2025 in Santa Clara, California, Robert Bosch GmbH was honored with the Best Automotive & Mobility Solution award for its groundbreaking SMP290 tire-pressure sensor module. Recognized for its advanced integration of Bluetooth Low Energy (BLE), the sensor sets a new benchmark for smart tire monitoring systems, combining precision sensing with wireless connectivity in an ultra-compact design.
The SMP290 stands out as the first single-chip TPMS (Tire Pressure Monitoring System) solution with integrated Bluetooth 5.3, enabling real-time data transmission and over-the-air (OTA) updates. Unlike traditional sensors, it merges multiple functions into a 3.5 x 4.5 mm package, including:
High-accuracy pressure sensing (up to 9 BAR for passenger cars, 15 BAR for commercial vehicles)
2-axis accelerometer (measuring up to 960g for dynamic vehicle tracking)
Temperature and battery voltage monitoring
Encrypted BLE communication (complying with ISO 21434 cybersecurity standards)
This integration eliminates the need for additional modules, reducing manufacturing complexity with just 12 passive components required.
The SMP290’s BLE 5.3 integration unlocks advanced features like:
Automatic tire autolocation (precise wheel position detection)
Direct smartphone alerts for low pressure or inflation needs
Shared vehicle communication networks (compatible with keyless entry systems)
By leveraging existing BLE-enabled vehicle architectures, the sensor cuts wiring redundancy, streamlining production while enhancing functionality.
Bosch’s collaboration with Pirelli (announced in 2024) validates the SMP290’s real-world application, merging Bosch’s sensor expertise with Pirelli’s Cyber Tyre tech for predictive tire health analytics. Judges praised its "seamless fusion of MEMS and BLE innovation", highlighting its market-ready design.
With 10-year battery life, 125°C operating tolerance, and ±5 kPa pressure accuracy, the SMP290 is tailored for passenger cars, commercial fleets, and electric vehicles. Slated for Q4 2025 availability, it debuted at Car-Ele Japan 2024, signaling Bosch’s leadership in automotive IoT.
As a global pioneer in MEMS and automotive electronics, Bosch continues to push boundaries in connected mobility. The SMP290 exemplifies its commitment to smarter, safer, and more efficient vehicle systems.
