Three-axis acceleration sensor has four measuring ranges

MEMS-based capacitive measuring is the basis for the WSEN-ITDS three-axis acceleration sensor by Würth Elektronik. It measures just 2.0 x 2.0 x 0.7mm and is  offered in an LGA package.

It has an integrated temperature sensor, enabling the sensor outputs to calibrate data directly. Four measuring ranges are available for selection: ±2, ±4, ±8 or ±16g. Register settings can be used to select the application-specific functionalities for free fall, wake-up, tap, activity, motion and orientation detection.

The WSEN-ITDS acceleration sensor can be used in a variety of applications; its high-resolution with up to 1,600 Hz output data rate is suitable for vibration monitoring, such as in the predictive maintenance of machines, or in low-power mode for recording a single pulse when a switch is touched. The energy-saving sensor can also be operated with energy harvesting. The ability to use integrated algorithms to prepare the measured data for application cases makes application development far easier, argues Würth Elektronik.

The WSEN-ITDS is specified for operation over a temperature range of -40 to +85 degrees C. This makes it suitable for industrial applications, such as decentralised measurement data acquisition in IoT networks.

Würth Elektronik offers developers intensive design-in consultation. The sensors can be ordered from stock without a minimum order quantity.

An evaluation board for the sensor is also available.
