Overview
The ADXL325BCPZ is a small, low-power, complete 3-axis accelerometer produced by Analog Devices Inc. This device is designed for applications where low power consumption and compact size are crucial. It measures acceleration with a minimum full-scale range of ±5 g, making it suitable for both static acceleration (tilt-sensing) and dynamic acceleration (resulting from motion, shock, or vibration).
