Monnit wireless accelerometers can be used in a host of applications where knowing impact, vibration, inclination, etc. is required.

The ALTA Wireless Accelerometer - G-Force Max/Avg sensor measures the maximum and average g-force values along X, Y and Z axes. A heartbeat can be set to determine how long the sensor will accumulate data for before reporting in. Custom Delta values allow for the user to set thresholds which, when exceeded, will trigger the sensor to report in immediately. Configurable data rates allow for more samples to be collected for every measurement with higher data rates resulting in faster reaction time. The data reported is useful for tracking periodic motion and event detection. There are six operating modes, 2 G, 4 G, or 8G each with an additional mode which employ a High Pass Filter. The data displayed is the g-force on each axis, e.g. –> X: 0.001 Y: 0.031 Z: 1.01. A Re-arm time can be configured such that the sensor will not trigger too quickly after being triggered once.

These accelerometers do not "stream" continuous data. Please reference the data sheet for further information.


  • Instant G-force detection alerts with details for quickly assessing a situation
  • Four data rates: 6Hz, 12Hz, 50Hz, 100Hz
  • Provides the following for 3 axes (X,Y and Z):
    • Raw, full-spectrum G-force maximum
    • Raw, full-spectrum G-force average
    • Magnitude maximum
    • Magnitude average
  • Sensor orientation status for near real-time awareness
  • 1-4 year battery life, depending on data rate selected
  • Three resolution settings: 2G/4G/8G/2G HPF/4G HPF/8G HPF

  * Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
