Sensing solutions for drones

Drones

Photography, agriculture, transportation security or simply entertainment: new applications for drones seem to emerge constantly. Initially, most drones were relatively simple toys. More recently, however, their flying capabilities have improved significantly, making them safer, more stable, and easier to control, and thus allowing them to be used for a much wider range of real life applications. One key requirement for drone 'pilots' is the low weight with maximum functionality which increases flight control and largely contributes to a smooth and optimal user experience. In addition, high accuracy as well as different flight modes are essential features influencing purchase decisions of consumers.

BMM150

BMM150

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.

BMI088

BMI088

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.
