Sensing solutions for drones

The low-power, low-noise BMM150 is a 3-axis digital geomagnetic sensor that perfectly matches the requirements of compass applications. By means of sensor data fusion software tailored to the hardware, the BMM150 provides absolute spatial orientation and motion vectors with high accuracy and dynamics. The BMM150 is also especially suited for supporting drones in accurate heading. The BMM150 can be used together with an inertial measurement unit consisting of a 3-axis accelerometer and a 3-axis gyroscope such as Bosch Sensortec’s BMI055.

The BMI088 is a high-performance 6-axis inertial sensor that allows for highly accurate measurement of orientation and detection of motion along three orthogonal axes. Consisting of a 16-bit digital, triaxial accelerometer and a 16-bit digital, triaxial gyroscope, the BMI088 is unique in the class of high-performance IMUs used in harsh environments such as those ones in drones and robotics applications. Apart from its high vibration robustness, the excellent temperature stability of BMI088 helps reducing design efforts and costs on a system level.

The BMP581 is the new benchmark in the field of barometric pressure sensors and impresses with its enormous accuracy. This enables endless and new use cases such as fitness tracking where accurate altitude change is key. The low power and low noise 24 bit absolute barometric pressure sensor significantly improved its accuracy compared to previous generations at smallest size. It offers outstanding design flexibility, providing a single package solution that customers can easily integrate into a multitude of existing and upcoming devices such as GPS modules, wearables, hearables, smart home, IoT and industrial products.

The BMP390 is a very small, low-power and low-noise 24-bit absolute barometric pressure sensor. The digital, high-performance sensor is ideally suited for a wide range of altitude tracking applications. This new BMP390 pressure sensor offers outstanding design flexibility, providing a single package solution that customers can easily integrate into a multitude of existing and upcoming devices such as smartphones, GPS modules, wearables, hearables and drones.

The BME688 is the first gas sensor with Artificial Intelligence (AI) and integrated high-linearity and high-accuracy pressure, humidity and temperature sensors. It is housed in a robust yet compact 3.0 x 3.0 x 0.9 mm³ package and especially developed for mobile & connected applications where size and low power consumption are critical requirements. The gas sensor can detect Volatile Organic Compounds (VOCs), volatile sulfur compounds (VSCs) and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range.

Bosch Sensortec’s sensor fusion software BSX is a complete 9-axis fusion solution which combines the measurements from 3-axis gyroscope, 3-axis geomagnetic sensor and a 3-axis accelerometer to provide a robust absolute orientation vector. The sensor fusion software BSX provides orientation information in form of quaternion or Euler angles.
