Versatile three-axis acceleration sensor

02/10/2019

Würth Elektronik has expanded its sensor programme with a compact, versatile three-axis acceleration sensor. Measuring only 2.0 × 2.0 × 0.7 mm, the WSEN-ITDS sensor, is offered in a land grid array (LGA) package and uses a microelectromechanical systems (MEMS)-based capacitive measuring principle. Thanks to an integrated temperature sensor, the sensor outputs calibrate data directly. Four measuring ranges are available for selection: ±2, ±4, ±8 or ±16 g. Register settings can be used to select the application-specific functionalities for free fall, wake-up, tap, activity, motion and orientation detection. The acceleration sensor can be used in a variety of ways; for example, it offers high resolution with up to 1,600 Hz output data rate for vibration monitoring, such as in the predictive maintenance of machines, or can be used in low-power mode for recording a single pulse when a switch is touched. In this case, the energy-saving sensor can even be operated with energy harvesting. The ability to use integrated algorithms to prepare the measured data for application cases makes application development far easier. The WSEN-ITDS is specified for a temperature range of –40 to +85°C.
