How To Use my Zephyr HxM with AIRS?

Our AIRS platform supports recording values via an attached Zephyr HxM heart rate monitor. This monitor is a belt-worn BT-enabled sensor, which can record current pulse, instant speed as well as distance travelled. In the following, we will show you how to configure and use the Zephyr HxM within AIRS as well as Storica.

First, you will need to prepare your HxM for using with AIRS by pairing your HxM with your Android device. For this, you need to go into the System settings under Bluetooth. Scan for available devices and select the HxM device once it shows up. Pressing on the HxM entry will initiate a pairing attempt with the device with ‘0000’ being the standard PIN to be used.

Second, you will now need to configure AIRS appropriately. For this, start AIRS and select the Config tab.



Select the ‘Heart Monitor’ entry in the list, bringing you to the following screen:



Enable the use of the heart monitor with the check mark. Then press ‘Device Selection’. If you successfully paired your HxM in the previous step, you will see a list of all your paired BT devices, such as



Select your HxM device (HXM022872 is the one I am using).

Now you are all done to use your heart monitor in AIRS! You can define an Averaging Window (see above) for the recorded values. The default value is 5s and is a recommended tradeoff between number of values being stored (i.e., one per 5 seconds) and the accuracy. You can lower this value to 1s (which creates many more values) or increase it, if you like.

In order to record, you now need to select the appropriate sensors in your Sensor list. For this, press Select Sensors in the screen below:



This will bring up the list of sensors supported on your device:



If you enabled the heart rate monitor usage (see above), you should find the following sensors in this list:

  • HP: pulse
  • HI: instant speed
  • HL: battery level

Select any of these sensors to record the appropriate value from your HxM (we currently do not support distance travelled).

If you start recording now, AIRS will try to initially connect to the HxM, so make sure that the sensor is properly installed (i.e., on its belt with appropriate lubrication to pick up measurements). If there is no sensor detected, AIRS will show a text in the sensor list, indicating that it could not connect to the sensor. If the connection was successful, you will see frequent updates of the values (according to your choice for the averaging window). If the connection drops during the recording, AIRS will try to re-connect every 15 seconds.

How do I make use of the Recordings in Storica?

Let us briefly explain how to use the recordings in Storica. You can view all values, i.e., the pulse, instant speed and the battery level in the detailed view for each day. With this, you can monitor your pulse, for instance, in detail.

If you recorded your pulse, you will also see Calories Expenditure in the list for detailed visualisations. This calculation is based on your settings regarding age, weight and gender (under the Settings->About Me menu).

In addition, we visualise your pulse and speed in the context panels within your stories, the map view and the media gallery. Specifically, you can see symbols for standing, walking, running (the driving symbol is shown when the GPS speed is recorded in addition). Furthermore, we show a heart symbol with a color that changes with the average pulse in the time window considered. Click on any of these symbols to see the detailed timelines!
