Bosch’s SMP290 is a compact smart tire pressure monitoring sensor (TPMS) that redefines the possibilities of MEMS technology, representing a bold leap forward in automotive safety.
The SMP290 measures just 3.5 x 4.5 millimeters; despite its small size, it is packed with innovation. This groundbreaking sensor is the first to directly integrate Bluetooth Low Energy (BLE) into a MEMS-based TPMS sensor. It is tailored for a variety of vehicles, from motorcycles to trucks, integrating pressure sensors, temperature sensors, a dual-axis accelerometer, a microcontroller, and a BLE interface into a streamlined chip.
Thanks to its ultra-low power design, the SMP290 can operate for up to 10 years on a single battery, supporting both valve-mounted and in-tire installations. However, its true advantage lies in its connectivity: the BLE interface enables real-time monitoring, seamless communication with smartphones, and even over-the-air updates, which is rare among similar sensors.
The SMP290 is not just an upgrade; it represents a system-level rethinking. By utilizing BLE for tire data transmission, it simplifies vehicle architecture and reduces the need for redundant components. It can even share BLE infrastructure used by other systems, such as keyless entry, paving the way for a more unified and efficient vehicle design.
This innovation has not gone unnoticed. The SMP290 has been nominated for the Best Sensor Award in the Automotive and Mobility sector for 2025. Bosch has produced over 23 billion sensors, reaffirming its global leadership in sensor technology.
The SMP290 not only heralds smarter tires but also smarter, more connected vehicles. Bosch is not just a leader in the wave of innovation; it is also a driving force behind it.
