The MMA9555L 3 axis acceleration sensor module is a smart pedometer that expands upon the capabilities of the MMA955xL sensor platform. It is equipped with a 3-axis MEMS accelerometer, signal conditioning, data conversion, and a 32-bit microcontroller. This advanced sensor offers features such as pedometer tracking, activity level monitoring, and six directional orientation detection.

By combining sensor initialization, calibration, data compensation, and computation functions, the CPU bandwidth required for the system application processor is reduced. Consequently, overall power consumption is greatly decreased as the application processor can remain shut down until necessary. Additionally, this device offers an optional autosleep/autowake feature for added convenience.

Features:

• This MMA9555L 3 axis acceleration sensor module boasts an impressive high resolution and a 16-bit ADC, delivering a precise measurement of 0.061 mg/LSB at 2 g.
• Choose from various g ranges (±2/4/8 g) and output data rates (488 Hz–3.8 Hz).
• One SPI or I2C interface serving as a slave and facilitating communication with the host processor at speeds up to 2 Mbps.
• A supply voltage of 1.8 V results in low power consumption.
• At stop mode, the standard current is usually 2 μA.
• The pedometer consumes 117 μA while running in active mode, and 92 μA while in suspend mode.
• At six-direction detection mode, the current is -87 μA.
• Fully equipped embedded firmware for advanced sensing capabilities.
• Optimizing task scheduling in both real-time and preemptive environments.
• The command interpreter facilitates both command/response and streaming mode.
• This pedometer boasts low-power capabilities and provides a wealth of output information including step count, speed, distance, estimated calorie burn, and activity level (rest, walking, jogging, running).
• The output of six-direction detection.
• A wide range of power-saving capabilities and a mode for reduced energy usage.
• GPIO2 to GPIO8 can be utilized for extending the range of configurable GPIO functions.
• External component requirements are kept to a minimum.
