Würth Elektronik is expanding its range of compact MEMS-based sensors with a 3-axis accelerometer and integrated gyroscope.

Its selectable measuring ranges and data rates make WSEN-ISDS extremely versatile. To facilitate 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 2.5x3.0x0.86mm sensor in an LGA package provides digital I²C and SPI interfaces as well as a FIFO buffer for storing output data.

Countless applications await the WSEN-ISDS 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 selected up to 1400Hz 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.

From a light breeze to an intense tremor

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

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