Overview
The ADXL203CE is a high precision, low power, complete dual-axis accelerometer produced by Analog Devices Inc. This device features signal conditioned voltage outputs on a single, monolithic IC and is capable of measuring both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity). It is widely used in various applications such as platform stabilization/leveling, navigation, alarms and motion detectors, high accuracy 2-axis tilt sensing, vibration monitoring and compensation, and abuse event detection.
