Motion sensor combines accelerometer and gyroscope functions

MEMS-based sensors from Würth Elektronik now include the WSENS-ISDS three-axis accelerometer and integrated gyroscope. It has selectable measuring ranges and data rates.

For ease of integration, the sensor outputs pre-calibrated, processed data for application-specific functionalities of free-fall, wake-up, tap, activity, motion, tilt and orientation detection. The 2.5 x 3.0 x 0.86mm sensor is in an LGA package to provide digital SPI and I²C interfaces as well as a FIFO buffer for storing output data.

The compact accelerometer and gyroscope can be used for localisation and navigation, automation, industrial devices and machines, antenna and platform stabilisation, through to industrial IoT devices, robots and drones. 

Linear and angular acceleration measurement extends from single-event registration to high frequency continuous vibration monitoring. Data rates can be selected up to 1,400Hz for the accelerometer and up to 937Hz for the gyroscope. The output data rate extends to 6.66kHz. The module draws 0.69mA in high-power mode, but this goes down to 0.28mA in low power mode to capture single pulses.

The user can select different measuring ranges depending on the level of acceleration the WSEN-ISDS is to detect. Würth Elektronik offers ±2 g, ±4 g, ±8 g, ±16 g for linear acceleration and ±250 dps, ±500 dps, ±1000 dps, ±2000 dps for the change of angular velocity. The sensitivity accuracy is ±3 per cent.

The WSEN-ISDS sensor is available from stock without a minimum order quantity. Würth Elektronik offers developers design-in consultation.
