2-Axis Tilt Sensing Computer Peripherals Inertial Navigation Seismic Monitoring Vehicle Security Systems Battery Powered Motion Sensing Low Cost ؎2 g/؎10 g Dual Axis iMEMS® Accelerometers with Digital Output ADXL202/ADXL210GENERAL DESCRIPTION
The ADXL202/ADXL210 are low cost, low power, complete 2-axis accelerometers with a measurement range of either ± 2 g/ ± 10 g. The ADXL202/ADXL210 can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity). The outputs are digital signals whose duty cycles (ratio of pulsewidth to period) are proportional to the acceleration in each of the 2 sensitive axes.
