Monitor acceleration on three axes in real time

The G-Force Max/Avg Wireless Accelerometer delivers detailed, real-time G-force alerts. This broad-spectrum vibration meter can determine if a fence is swaying in the wind or vibrating as it’s being scaled. It can also detect irregularities in assembly lines, motors, and wind turbines.

This sensor reports the maximum and average g-force levels that occur on X, Y, Z, and combined axes in-between sensor heartbeats. The sensor uses a digital, low power, low profile, capacitive accelerometer capable of measuring acceleration on three axes to produce this data. The turnkey, battery-powered sensor uses an accelerometer to determine which axis the force is on and max./avg. movement force. If variables exceed preset limits, the sensor alerts the user via text, email, or call.

The sensor employs a MEMS (micro electromechanical system) based accelerometer to detect forces caused by acceleration. These forces may be static such as the constant force of gravity, or they may be dynamic - caused by moving or vibrating the sensor. A user may set thresholds (defined as Delta Values in the user interface) for each axis (X, Y, Z) as well as a magnitude threshold, such that when thresholds are exceeded the sensor will trigger and report data to iMonnit immediately.

The sensors accelerometer uses three configurable settings (Output Data Rate(ODR), Range, and High Pass Filter(HPF)) to refine the measurement capabilities of the sensor for various applications. ODR controls the responsiveness of the sensor. The highest ODR (100 Hz) will trigger in under a second, where the lowest ODR (6 Hz) will take up to 5 seconds to trigger. The sensor is constantly measuring and higher ODRs result in short battery life. The range can be set to 2, 4, or 8 g. There is a small loss of resolution as the range increases. Generally, even at 8 g, the resolution is sufficient for most applications. When the High Pass Filter is activated the sensor filters out static g-forces such as gravity. A user may also set a re-arm time, which establishes the time after the sensor triggers before the sensor may trigger again. The X, Y, Z data correlates directly with the specified axis and the magnitude data is the summation of the absolute value of the XYZ data.

Monnit Gateway Options

An integral component of any IoT network is the gateway. A gateway device allows for data from sensors to be transmitted to the iMonnit software platform.


Monnit Ethernet Wireless Gateway 4

Monnit’s Ethernet Gateways allow your Monnit Wireless Sensors to communicate with the iMonnit™ Online Wireless Sensor Monitoring and Notification System without the need for a PC. Simply provide power and plug the gateway into an open Ethernet network port with an internet connection. It will then automatically connect with our online servers, providing the perfect solution for commercial locations where there is an active internet connection.

Monnit 4G + Ethernet IoT Gateway

The ALTA® by Monnit Wireless IoT Gateway combines a 4G LTE CAT-M1/NB2 cellular engine and Ethernet platform with Monnit’s wireless access point network to aggregate and communicate data from Monnit ALTA Wireless Sensors. The ALTA IoT Gateway allows ALTA Sensors to operate on the world’s leading cellular networks and stay connected to the Internet. The gateway uses AC main power but also has redundant power through a battery backup lasting up to 60 hours.

To meet the global demand for enterprise IoT deployment, the IoT Gateway communicates with the cloud-based iMonnit® monitoring software via cellular transmission, making it ideal for remote locations or where the Internet isn’t available. The RJ-45 Ethernet jack allows local device configuration, diagnostics, and connectivity backup. The IoT Gateway is instrumental in sending sensor notifications via text, email, or call if user-defined conditions are met or exceeded.

Keep your business running smoothly with Monnit's accelerometers

Monnit’s range of wireless accelerometers are a digital, low power, low profile capacitive sensor that can measure acceleration on three axes. Accelerometers are used in all types of electronic devices today, most notably in smartphones to change the screen orientation when rotated. Monnit offers 5 different types of accelerometers that be particularly useful in heavy mechanical environments.


Get real-time data to protect assets

The first type of accelerometer sensor is Monnit’s Tilt Sensor. This accelerometer activates at a set time interval (defined by the user) and converts measurements to pitch and roll in terms of degrees. If you think about a flying plane, pitch refers to the up and down movement, and roll refers to the clockwise or counter-clockwise rotation of the plane around the x-axis.

See the Monnit Enterprise Tilt Wireless Sensor for more information


Next are Monnit’s G-Force Snapshot and G-Force Max/Average Sensors. These sensors measure g-forces (up to 8G) on the X, Y, and Z axes. Based on the sensor you select, readings are displayed as either a single ‘snapshot’ when the sensor activates at its set interval or the ‘max/average’ of the movement since the last reading.

See the Monnit G-Force Snapshot and G-force max/Average Sensors for more information


Monnit’s Impact Detection Sensor activates and displays readings only when the sensor experiences sudden movement. This sensor can also be set to trigger above certain G-force levels, alerting the user of any unexpected movement.

See the Monnit Enterprise Impact Wireless Sensor for more information


Finally, Monnit offers an Advanced Vibration Meter. Like other accelerometers, this sensor measures G-force on 3 axes to determine speed and frequency. Sensors can be set to only capture when a vibration occurs and sleep when no vibrations are present or to measure at a given assessment interval regardless of whether a vibration has occurred or not.

See the Monnit Enterprise Advanced Vibration Wireless Meter for more information


Drop-in for deeper machine insight

These accelerometer sensors are very useful for manufacturing environments as they are primarily used to predict, and consequently prevent mechanical failure. For example, if a motor experiences increased vibration levels, this can be a good indicator that bearings are worn, and the motor is close to failure. An alert will allow engineers to respond in time to a malfunctioning machine before it completely breaks, ultimately saving time and money. Monnit’s range of accelerometers paired with an applicable Gateway and iMonnit software, make it easy to set up a system that can do this.


A complete wireless network does not have to be complicated or confusing. Monnit wants to make it as easy as possible to implement a secure cloud network into your daily business operations. Simply place these sensors on a few critical components in your factory and evaluate the results over the first week to establish a proper rhythm. Once users know what is considered normal mechanical movement, notifications can then be set up and sent to any internet-enabled device when preset parameters happen to change.


Gain deeper insights to your company’s machines today and help eliminate problems early before they become expensive and time-consuming.
