WSEN-ISDS motion sensor — Image source: Würth Elektronik
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 makes 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 2.5 x 3.0 x 0.86 mm 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 localization and navigation solutions, to automation, industrial devices and machines, antenna and platform stabilization, 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 1400 Hz for the accelerometer and up to 937 Hz for the gyroscope. The output data rate extends to 6.66 kHz. The module draws 0.69 mA in high-power mode, but this goes down to 0.28 mA 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 ±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 percent.
The WSEN-ISDS sensor is always available from stock without a minimum order quantity. Würth Elektronik offers developers design-in consultation.
