MEMS sensors extended with new IMU AHRS and accelerometer solutions

Mouser has expanded its range of motion and positioning MEMS solutions. The continued expansion of technology and its closer integration into everyday life has amplified the importance of a device's ability to perceive its surroundings. Consumer applications like smartphone navigation and video game controllers rely heavily on components such as accelerometers and gyroscopes for locational and control information. In industrial settings, the significance of such sensors is also important. Gyroscopes, accelerometers, combined IMUs, and AHRSs all play a critical role in ensuring the effectiveness and safety of solutions ranging from automation and drones to navigation systems and platform stabilisation.

New motion and positioning product highlights available from the company include:

The FSM30x 9-Axis IMU/AHRS module from CEVA includes a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer, with a configurable sampling rate of up to 1KHz. MotionEngine technology supplies raw, calibrated, and fused sensor orientation data with best-in-class stability and accuracy. The 32-bit ARM Cortex M0+ MCU runs CEVA's Hillcrest Labs business unit high-performance sensor hub software stack and permits for intelligent power management with managed sensor state and low consumption for always-on applications. The modules feature advanced magnetic interference rejection algorithms and dynamic and factory calibration to ensure accurate measurement in various conditions. As a small (20mm x 25mm) turnkey solution featuring example driver code for Android, Linux, and embedded designs, the FSM30X helps for faster time-to-market and reduced project costs. Ideal applications include navigation, 3D audio, fitness and health monitoring, flight control systems, asset tracking, body motion capture, and AR/VR motion tracking.

The WSEN-ISDS from Würth Elektronik is an adaptable and simple to integrate 6-axis IMU. It supplies pre-calibrated output and processed data catering to application-specific functionality, including free-fall, wake-up, tap, activity, motion, tilt, and orientation detection. Within the small 2.5mm x 3mm x 0.86mm LGA package is a 3-axis acceleration sensor and 3-axis gyroscope sensor that feature selectable measuring ranges and data rates. The gyroscope permits data rates up to 937Hz, the accelerometer up to 1400Hz, and the output data rate extends to 6.6kHz, with a digital I2C and SPI interface and a FIFO buffer for storing output data. The measurement of linear and angular acceleration ranges from single-event registration to continuously monitoring of high-frequency vibrations. Applications for the WSEN-ISDS include robotics, drones, automation, localisation and navigation systems, industrial tools and machines, antenna and platform stabilisation, and IIoT solutions.

Available to order, the new ADIS16550 Six Degrees of Freedom inertial sensor from Analog Devices is a complete motion solution, including a tri-axis gyroscope and accelerometer. Combining industry-leading MEMS technology with advanced signal conditioning, each sensor's inertial sensor has optimised dynamic performance and is factory-calibrated for sensitivity, bias, and alignment across a 40C to +85C temperature range. Compared to the complexity and investment of discrete designs, the sensor offers a simple and cost-effective method for integrating accurate, multi-axis sensing into industrial systems, with the tight orthogonal alignment simplifying inertial frame alignment in navigation systems. The sensor is packaged in 47mm × 44mm × 15mm aluminium housing and includes an SPI with a register structure, which allows for simple data collection and configuration control. The triaxial, delta angle, and delta velocity outputs and robust 1500g mechanical shock survivability make the sensor ideal for precision autonomous machines and robotics, as well as navigation, guidance, and dead reckoning for GPS.

Created to provide high-accuracy single-axis vibration feedback, the LVEP-TO5 embedded accelerometer from Amphenol Wilcoxon is a high-performance piezoelectric accelerometer with an ultra-low 180μW power consumption. The accelerometers offer a 17kHz resonance frequency, <10ms bias output voltage settling time, and ±5% sensitivity tolerance, with an operational voltage as low as 3VDC and a current draw of just 60μA. The sensors are housed in standard TO-5 semiconductor packaging and have a hermetic seal that stops the passage of air, oxygen, and other gases. They can be easily integrated into wireless vibration sensors and other battery-powered applications with dimensions of 8.4mm x 9.6mm and a weight of only 3.2g. Typical applications include high-volume integrated appliances, wireless vibration sensors, and other battery-powered implementations, including motor vibration sensors and structural health monitoring solutions.
