Seven-Axis Motion and Pressure Sensor Fits Drone, Fitness, IoT Apps

InvenSense Gyro measures seven axes.

If three, four, five, or even six axes weren’t enough for you, TDK has developed the InvenSense ICM-20789 MEMS seven-axis integrated inertial device. The part combines a three-axis gyroscope, a three-axis accelerometer, and an ultra-low noise MEMS capacitive barometric pressure sensor. The ICM-20789 encompasses a single small footprint, with a low-pressure noise, just 0.4Pa RMS. In addition, excellent temperature stability is exhibited, with a temperature coefficient of ±0.5 Pa/°C.

This low temperature coefficient enables the temperature stable capacitive pressure sensor to measure pressure differences of ±1Pa, enabling the ICM-20789 to detect altitude changes of less than 5 cm. As a result, the part is well suited for drone applications, as well as wearables, navigation, and fitness/activity-monitoring products.

Housed in a 4- by 4- by 1.365-mm package, the InvenSense ICM-20789 is available immediately, as well as evaluation boards.
