 Hello! This video will introduce and explain the different functionalities of Sensortile.box. This is video number one and describes the entry-level mode. The Sensortile.box has three working modes. The first one, Entry Mode, enables the user to discover the sensor functionalities by providing some predefined functions and examples. This is a list of the pre-recorded examples available with the current Sensortile.box firmware release, barometer, compass and level, data recorder, pedometer, sensor fusion, and vibration monitoring. We are going to go through each of them in this video. Install the STBLE Sensor app on your smartphone from its Play Store. Run it and select the option Connect to a Device. In the list of recognized devices, you should see Tilebox. If not, please connect your device to your phone via the micro USB port. If Tilebox is visible, tap on it. The blue LED on the box will blink, signaling a connection is made. On the phone, you will get a new screen showing four icons. Three of them will have readings just beneath them. These readings are the measurements done by your Sensortile.box in real time. Please note that the Sensortile.box does not have a light sensor, so one icon is not enabled. The barometer application is running on the Sensortile.box automatically, and you can check out the readings immediately. It is also possible to log the data on the phone. Click on the button with three dots on the top right corner. Hit the Start Logging menu item to start the data logging. Hit the Stop Logging item when you want to stop. By swiping the screen to the left, you can also plot the data. First, select the feature to plot and then select the time scale. Data is plotted in real time. For example, ambient pressure can be seen changing in real time if, for example, you move the Sensortile.box up and down in the air by a few tens of centimeters. The app screen has some buttons at the bottom of the screen. These buttons can be used to access different screens. The first two have already been shown. The next one, Cloud Logging, will be explained in the next video. And the last one shows some useful information about the signal strength of the Bluetooth connection, RSSI, and the status of Sensortile.box battery. So, we've just checked out the barometer example. Now let's have a look at the other pre-recorded apps. Going back to the main app screen, let's select the Create Apps button. Please note that at the bottom of the new screen that opens, you have three sections, Start, Sensors, and More. Start is where the other apps are stored. Sensors is the list of all available sensors inside Sensortile.box. More is to get additional information and help. Inside the Start screen, you can browse a list of app examples that you can immediately try to run in your Sensortile.box. We've just checked out the first barometer app. What is interesting to note is that each app can be inspected and that each sensor that is being used or accessed has its own settings that can be modified. Each app has inputs, functions, and outputs. We will check these out in more detail in the next video. Let's see some other app examples. Let's try the second one, Compass and Level. From the main screen, hit Create Apps and then from the main Start menu, select Compass and Level. When the app screen opens, hit the pink Play button. Your Sensortile.box name should appear as available boards. If not, go back one screen and try again. When prompted to overwrite the board, hit OK. If the upload happened successfully, you can go back to the main screen where you can connect to your Sensortile.box to see data in real time. This time the data is represented by Euler angles. Move the Sensortile.box to see the graphs moving. By hitting the Compass button at the bottom of the screen, you can see a compass drawing pointing to the magnetic north. By hitting the Level button, you will see an animation with two circles representing inclinations. Another useful example is the Data Recorder. Let's move back to the Start page to click on it and to the next screen to upload and activate it. After having overwritten the previous app, let's go back to the main screen to connect to your Sensortile.box. This time there is no graphical view since data is stored inside the Sensortile.box. Logging can be started and stopped and will continue also if the cell phone gets disconnected by the Bluetooth. Data can be later retrieved by connecting the Sensortile.box to the micro USB port with a PC. Data logging in the app is still available as was described before. The difference is the number of samples you can save. This number is limited by the Bluetooth connection on the app so when a lot of information needs to be recorded, it is better to save it on the internal Sensortile.box memory. Another useful pre-recorded example is the Podometer. It counts steps when the Sensortile.box is attached to the belt. To activate it, as with the other examples, go to the Create app screen and upload it in the usual way. Accept to overwrite the previous app and connect to your Sensortile.box to run it. Please note the best accuracy is achieved when the box is applied to the belt. The first eight initial steps are not immediately shown to remove possible false steps. Sensor Fusion is not a fully finalized app but is used here to show a quick example of how to use different sensors, accelerometer, gyroscope and magnetometer to mutually compensate each other and get a more stable and accurate orientation estimation. This example loads in the same way as described for the others and has a graphical output where a simple dice is rotated in 3D on the screen representing the Sensortile.box as it moves in space. Before being able to see the dice, it's possible a magnetometer calibration is requested. In this case, just move the Sensortile.box in an 8-shape trajectory with your hand when prompted. Also, here a plot of the output is available, the four quaternions representing the absolute orientation in a 3D space can be seen in a graph. For more advanced users and for a typical industry 4.0 application, the vibration monitoring example is available. This example is composed of two steps, training and compare. The first part needs to be run loading the vibration monitor training app and will store the vibration spectrum of a machine in the Sensortile.box while it's in operation and when everything works correctly. Select and upload it in the standard way. During the run of this example, it's important no vibrations are given to Sensortile.box that have not been generated by the machine under test so it is important to keep the machine under test stable. After the first step has been completed, the second step can be run. This is called vibration monitor compare and is available in the create app screen like the other examples. Upload it on Sensortile.box when a machine verification test is needed. Now position the Sensortile.box on the machine exactly in the same position where it was when launching the first step. This second run will acquire the machine vibrations and compare them with what has been recorded during the first step. If differences are detected, this usually means the machine has some new vibration modes and these can be generated by defective or malfunctioning gears or parts. A deep machine evaluation is probably then recommended. Sensortile.box lessons will continue with the next video about the expert mode of operations. Stay tuned.
