Technical details and manufacturing context for Accelerometer

Definition
An accelerometer is a motion sensor component that detects and measures acceleration forces, including static gravity and dynamic motion-induced forces. Within motion sensor systems, it provides precise measurement of vibration, tilt, shock, and movement in various industrial applications. This component is typically fabricated using microelectromechanical systems (MEMS) technology, with a proof mass suspended by springs that moves relative to fixed electrodes when acceleration occurs. The resulting capacitance change is converted into an electrical signal proportional to acceleration. The device is available with a measurement range of ±2 to ±16 g, selectable via register, with lower ranges offering higher resolution. Sensitivity scales with range setting, from 16 to 128 LSB/g. Zero-g offset is factory calibrated at ±40 mg, with temperature drift applicable. Nonlinearity is ±0.5% of full scale (best-fit straight line), and cross-axis sensitivity is ±1% between orthogonal axes. Output data rate is programmable from 1 to 3200 Hz, with higher rates increasing noise. Supply voltage ranges from 1.71 to 3.6 V, with an internal regulator for the digital core. Current consumption is 0.5 to 1.0 mA at 1 kHz output data rate, lower in standby. Operating temperature range is -40 to 85 °C. The device can survive shocks up to 10000 g (0.1 ms half-sine, powered off). It comes in an LGA-16 package measuring 3×3×0.9 mm, with a typical weight of 0.05 g. Materials used include silicon, polysilicon, and glass. This directory entry provides reference parameters; for specific model applications, verify all values and standards with the legal manufacturer or supplier.
Working Principle
Accelerometers typically operate using microelectromechanical systems (MEMS) technology, where a proof mass suspended by springs moves relative to fixed electrodes when acceleration occurs. This movement changes capacitance, which is converted to an electrical signal proportional to acceleration. The device measures both static gravity and dynamic motion-induced forces, enabling detection of tilt, vibration, shock, and movement. The proof mass displacement is sensed capacitively, and the resulting signal is processed to output acceleration data. The measurement range and sensitivity are configurable via registers, allowing adaptation to different application requirements. The principle is based on Newton's second law, where force equals mass times acceleration, and the displacement of the proof mass is directly related to the applied acceleration.
