Overview
The ADXL343BCCZ, produced by Analog Devices Inc., is a versatile 3-axis, digital-output, low-g MEMS accelerometer. This device is designed for a wide variety of applications, offering selectable measurement ranges and bandwidth, as well as configurable built-in motion detection features. It measures acceleration with high resolution (up to 13-bit) and can detect static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. The ADXL343 is robust, surviving up to 10,000 g of shock and operating within a wide temperature range of −40°C to +85°C, making it suitable for use in harsh environments.
