7-axis motion and pressure sensor, did you know?

What is a 7-axis motion and pressure sensor? What does it do? Mouser Electronics, the industry's top semiconductor and electronic component distributor that focuses on new product introduction (NPI) and provides a wide range of product types, will start distributing TDK Group companies from now on ICM-20789 from subsidiary InvenSense. The industry's first 7-axis inertial and air pressure sensor integrates a 3-axis gyroscope, 3-axis accelerometer, Digital Motion Processor™ (DMP) and ultra-low noise MEMS capacitive air pressure sensor in a tiny 4×4 mm package.

The InvenSense ICM-20789, available from Mouser, integrates TDK's latest high-performance 6-axis motion sensor, which provides the most accurate rotational and linear motion tracking capabilities and simplifies sensor signal fusion. The gyroscope has a programmable full-scale range (FSR) from ±250 dps to ±2000 dps, while the accelerometer has a programmable FSR from ±2g to ±16g.

MEMS capacitive pressure sensors feature the industry's lowest pressure noise of 0.4 Pa RMS and ultra-low power consumption of 1.3 µA at 1 Hz. The sensor is capable of measuring extremely small pressure differences of ±1 Pa, allowing it to detect height changes of less than 5cm. It also offers a full pressure operating range of 30 to 110 kPa, and a temperature coefficient of ±0.5 Pa per degree Celsius ensures excellent temperature stability. sex.

This sensor can be evaluated with the DK-20789 SmartMotion® Platform Development Kit. The kit features a Microchip G55 microcontroller and comes with the required software, including InvenSense MotionLink, a GUI-based development tool. The kit's embedded motion driver (eMD) is configurable with parameters such as FSR, output data rate (ODR), low power or low noise mode, and host sensor interface (I²C and SPI). The DK-20789 is equipped with an on-board embedded debugger, which allows programming or debugging of the G55 microcontroller without the need for external tools.

ICM-20789 combines the performance of discrete devices in an integrated small package, not only reducing design costs, but also providing full range of motion sensing through sensor fusion for various applications, including activity monitoring, gesture recognition, stair counting, wearable Equipment, drone height determination and indoor/outdoor navigation. The above is the analysis of 7-axis motion and pressure sensor. I hope it can help you.
