MEMS provider STMicroelectronics has launched a new automotive-grade, 3-axis, low-g accelerometer sensor AIS328DQ, combining fuel-efficiency and small footprint with high precision and good performance, according to the company. The accelerometer targets an array of automotive applications, including vehicle tracking, event recording, abuse monitoring, and dead-reckoning for increased navigation capabilities. It can sense acceleration and convert the motion and tilt information into a high-resolution digital signal, transmitting it to a microcontroller through a standard SPI or I2C interface and providing output across user-selectable full-scale ranges of ±2g/±4g/±8g. The sensor is resilient and qualified to AEC-Q100, a stress-test qualification for automotive integrated circuits established by the Automotive Electronics Council. With a temperature range of -40 to 105°C, the sensor can be used inside the cabin or modules having self-heating components.
