Overview

MMA7361L MODULE.jpg

This is a breakout board for Freescale's MMA7361L three-axis analog accelerometer. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges. Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices.

Features

  • Two selectable measuring ranges (±1.5g, ±6g)
  • Breadboard friendly - 0.1" pitch header
  • Low current consumption: 400 µASleep mode: 3 µA
  • Low voltage operation: 2.2 V - 3.6 V
  • High sensitivity (800 mV/g at 1.5g)
  • Fast turn on time (0.5 ms enable response time)
  • Self test for freefall detect diagnosis
  • 0g-Detect for freefall protection
  • Signal conditioning with low pass filter
  • Robust design, high shocks survivability
