Product Description

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.

ALTA - Leading Enterprise Grade "Internet of Things" Solutions

ALTA sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,200+ feet through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allows ALTA sensors to have better interference immunity from other wireless devices.

Superior power management provides ALTA sensors with almost twice the battery life of Monnit’s standard wireless sensors.

  • Coin cell sensors typically last 3+ years.
  • AA and Industrial sensors typically last up to 12+ years.
ALTA products employ Monnit's new Encrypt-RF® Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages), so security is maintained at all communication points from sensor to gateway, gateway to software, then back again.

Integrated on-board data storage allows ALTA sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can’t be delivered will be time-stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.

Over-the-air updates allow ALTA products to be updated remotely if new fixes or features become available.

The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 - 3.8 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.

Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.


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