MMA7455 3-Axis Accelerometer Module
The Freescale Semiconductor MMA7455L 3-Axis Digital Output Accelerometer is a low power, micro machined sensor capable of measuring acceleration along its X, Y, and Z axes. It offers several convenient integrated features including an analog to digital converter (ADC), digital low-pass filter, and selectable sensitivity ranges of ±2g, ±4g, or ±8g. This device can be easily configured to detect quick motion pulses as single taps, double taps, and 0g (free fall) conditions on any or all axes and provides configurable interrupt pins (INT1 and INT2) for each type of event.
Flexibility and compatibility are designed into this module. An on-board voltage regulator and I/O voltage level-shifters make this module especially easy to connect to virtually any microcontroller. It operates over a wide range of supply voltages from 2.5 VDC to 5.5 VDC and communicates via Serial Peripheral Interface (SPI) or Inter-Integrated Circuit (I2C) bus.
Features:
Wide supply voltage compatibility range.
Selectable sensitivity: 8-bit mode (±2g/±4g/±8g) or 10-bit mode (±8g).
User configurable interrupts (INT1/INT2).
User settable registers to calibrate each axis.
Compatible with virtually any microcontroller.
On-board voltage regulators and I/O level shifters for added convenience.
Low current operation.
Compact, breadboard-friendly package: 0.5 inch x 0.6 inch (12.7 mm x 15.2 mm).
Application Ideas:
Inertial Measurement Units
Tilt Sensing for remote controls
Single-tap or Double-tap user Input
Free-fall detection
Model airplane flight stabilization
Multi-axis vibration measurement
Motion sensing and data logging
Key Specifications:
Operating Voltage: 2.5V - 5.5V.
