Barometric pressure sensor BMP581


The BMP581 is the new benchmark in the field of barometric pressure sensors and is ideally suited for a wide range of altitude tracking applications like GPS modules, wearables, hearables, smart home and industrial products. This sensor is available via our distribution partners.

More about BMP581

Building on the excellent performance and low power consumption of previous generations of Bosch sensors, our new BMP581 now delivers an entirely new level of accuracy.

Frequently asked questions

You have questions regarding the new barometric pressure sensor? Have a look at the frequently asked questions:

BMP581 has 2 small lid holes with only limited protection against water, but BMP581 is much more protected against particles compared to BMP388 or BMP390.

Typical applications of the BMP581 are:

  • Enhancement of GPS navigation (e.g. time-to-first-fix improvement, dead-reckoning, slope detection)
  • Indoor navigation (floor detection, elevator detection)
  • Outdoor navigation
  • Sports applications like calorie counting, fitness activity identification
  • Emergency caller location
  • Weather forecast
  • Altitude control of drones and flying toys

Devices in the consumer electronics for the BMP581 are:

  • Handsets such as mobile phones, tablet PCs, GPS devices
  • Navigation systems

Technical specifications:

BMP581 has a typical current consumption of (typ.) 1.3 µA @ 1 Hz for pressure and temperature.

The absolute accuracy is ± 30 Pa (typ.) between 300 – 1100 hPa, -5 – 65 °C.

The TCO (temperature coefficient of offset) of the BMP581 is ± 0.5 Pa/°C (typ.) between 300 – 1100 hPa, -5 – 65 °C in 10 K steps.

The relative accuracy is ± 6 Pa (typ.) of the BMP581 is 700 – 1100 hPa, 15 – 55 °C, in 10 kPa steps.

The pressure noise of the BMP581 is 0.21 (typ.) PaRMS in OSR set to “high resolution”.
