Motion sensor comprises accelerometer and gyroscope in one

27-03-2023 | Wurth | Test & Measurement

Würth Elektronik is growing its range of compact MEMS-based sensors with a three-axis accelerometer and integrated gyroscope. Its selectable measuring ranges and data rates make the WSEN-ISDS extremely versatile. To facilitate integration, the sensor outputs pre-calibrated, processed data for application-specific functionalities of free-fall, tap, wake-up, activity, motion, tilt and orientation detection. An LGA package's 2.5mm x 3mm x 0.86mm sensor provides digital I²C and SPI interfaces and a FIFO buffer for storing output data.

Countless applications await the compact accelerometer and gyroscope: from localisation and navigation solutions to 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 chosen up to 1400Hz for the accelerometer and 937Hz for the gyroscope. The output data rate extends to 6.66kHz. The module draws 0.69mA in high-power mode, down to 0.28mA in low-power mode, to capture single pulses.

The user may select different measuring ranges depending on the level of acceleration the device is to detect. Here, the company offers the ranges ±2g, ±4g, ±8g, and ±16g for linear acceleration and ±250dps, ±500dps, ±1000dps, and ±2000dps for the change of angular velocity. The sensitivity accuracy is ±3%.
