Bosch Sensortec has launched a 9-axis motion sensor in a 2.5 x 3.0 x 0.95 mm3 package, claiming it to be the world’s smallest.
BMX160 includes accelerometer, gyroscope and geomagnetic sensors, and typically consumes 1.6mA.
“It is ideally suited for applications such as smartphones, smart watches, fitness trackers, smart glasses, smart jewelry – rings and necklaces – as well as augmented reality and virtual reality devices,” said the firm.
It is pin and register-compatible with the firm’s 6-axis BMI160, which does not have a magnetic sense.
Power management options allow it to remain in sleep mode, for example when counting steps. The integrated step-counter function and the Android compatible significant motion detector consume 30µA each.
Samples are available for development partners.
