# Understanding sensor measurements and monitoring machine abnormalities
Amazon Monitron monitors temperature and vibration data from sensors and watches asset conditions for abnormalities that might indicate developing faults. You monitor your assets either with the Amazon Monitron web app, or with the Amazon Monitron mobile app, which you download and install on your smartphone. Amazon Monitron supports only smartphones using Android 8.0\$1 or iOS 14\$1 with Near Field Communication (NFC) and Bluetooth.
This topic describes how to read sensor measurements, respond to notifications about machine abnormalities, and take one-time measurements.

# Choosing your measurement viewing platform
There are two ways to use Amazon Monitron to view your assets' measurements and abnormalities. You can view them in the mobile app, or you can view them in the web app. Each way has its advantages.
With the mobile app, you use your phone's Bluetooth and Near Field Communication (NFC) capabilities to install and configure gateways and sensors, as explained in [Wi-Fi gateways](setting-up-Wi-Fi-gateways.md).
With the web app, you download your data to a .csv file. Also, your monitor is probably bigger than your phone, so the web app may be a better place to see measurements using line graphs.
You can activate either the mobile app or the web app by clicking on a link to your project. This is the link that the administrator sends to the user, as explained in [Sending an email invitation](resending-email.md). But you can re-generate this link from the **Projects** page by selecting a user and then choosing **Email instructions**, or by choosing **Copy link** under **Project details.**

## In-app updates
For access to the latest Amazon Monitron features, regularly check your mobile device for updates. Periodically, Amazon Monitron releases new application versions that you'll need to manually update if you don't enable automatic updates. These notifications will be provided on the web app as they become available.
**Flexible and immediate updates**
Amazon Monitron provides two kinds of in-app updates: flexible and immediate. **Flexible updates** allow you to elect whether or not to update the Amazon Monitron app once you’ve signed in. **Immediate updates** contain security updates, and must be installed in order to use the app. You can install updates from the Amazon Monitron app, or directly from Google Play or the App Store.
To manually install the latest updates:
1. Sign in to the Amazon Monitron app and choose **Update**.
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/Monitron/latest/user-guide/platform-chapter.html)
1. When you select **update**, you'll be directed to Google Play or the App Store. Select **Update** or **Install** to start the update.
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/Monitron/latest/user-guide/platform-chapter.html)
1. If you start the update process within the Amazon Monitron app, you'll see a success message in the app once the update has been installed.
![\[Mobile app interface showing successful update to version 1.0.0 with a list of assets below.\]](http://docs.aws.amazon.com/Monitron/latest/user-guide/images/app-update-success-screen.png)
**Note**
You will not see the success message if the update happens automatically, or if you initiate the update process within the App Store or Google Play.
# Viewing sensor measurements
You can choose to view your sensor measurement data in two chart formats: scatter plot and line plot. The following image shows the scatter plot view on the top and the line plot view on the bottom.
**Note**
You can select your sensor measurement view from the **Chart type** menu in your mobile and web app.
![\[Dashboard showing vibration data for Position name 3, with warning alerts and graphs.\]](http://docs.aws.amazon.com/Monitron/latest/user-guide/images/scatter-plot-chart-measurement.png)
# Understanding sensor measurements
When a sensor is initially paired to an asset, Amazon Monitron will learn from the vibration and temperature data collected from the equipment, establishing a baseline to determine what is "normal" for that asset. It will use this learning to detect potential failures in the future.
Depending on the situation, operational scenario, use case, and various parameters like the asset’s duty cycle, Amazon Monitron will take between 14 and 21 days to establish this baseline. During this initial learning and training phase, the asset is assumed to be healthy.
After establishing a baseline for the asset, Amazon Monitron monitors the data it collects, looking for an event or trend that indicates a potential failure. It specifically watches for increases in temperature, or vibration levels, or both. Increases in temperature and vibrations are two of the main indicators of a malfunctioning machine. Machine abnormalities often indicate that an asset is starting to fail.
Amazon Monitron uses vibration thresholds established by the International Organization of Standardization (ISO) for your class of machinery. It applies the ISO thresholds in combination with its self-training model to assess actual thresholds to fit your equipment. For example, if your machine runs a little hot or a little cold, or if it vibrates a little bit more than standard, Amazon Monitron adjusts the thresholds slightly so that it can more accurately identify when the machine is acting abnormally.
The only alarms you will recieve during the initial learning and training period will be from the ISO model (which does not require any learning period). You should treat ISO alarms during the training period as you would any alarm—acknowledge the alarm, perform any necessary review of the machine, and then close out the alarm with the suitable action taken code. After that time, Amazon Monitron continues to fine-tune the baseline, building a better picture of "normal" as the sensor collects more data.
If temperature or vibration levels inconsistently rise above the modified threshold, a failure might be possible, but is probably not imminent. In that case, Amazon Monitron sends a `Warning` notification. If the increase is consistently above the threshold, the conditions are clearly abnormal and a failure is much more likely. Under those circumstances, Amazon Monitron sends an `Alarm` notification to the mobile or web app.
