Real-Time Data Collection

The Data Studio can perform real-time data collection and labeling from any sensor over Serial COM, Bluetooth-LE, or Wi-Fi radios. You can use any third-party device in the Data Studio by updating the device firmware to our open-source Simple Streaming Interface (SSI).

Open Live Capture Mode

Next, we are going to go over how to use Live Capture Mode within the Data Studio to collect data from a sensor in real-time.

  1. Open your project in the Data Studio

  2. Click on the Live Capture button in the left navigation bar

Configure Your Sensors

Next, we are going to setup the sensor settings we will use for data collection.

  1. Click the sensor Connect button

  1. Select a connection protocol. The connection protocol will depend on what your device firmware has implemented for data collection. We recommend using the Simple Streaming Interface (SSI). We provide example firmware for a range of dev kits, see the Flashing Data Collection Firmware Documentation

Start Recording Data

Before you can use your device for data collection make sure it is flashed with data collection firmware. You can find more information on data collection firmware options and flash instructions in the Flashing Data Collection Firmware Documentation.

  1. Click Connect to connect to your device

  1. (Optional) You can record video from a webcam or screen capture to sync with your sensor data. The Data Studio uses the SensiML Open Gateway application to record video. See the SensiML Open Gateway documentation for more details

  1. Click Start Recording and the Data Studio will start recording based on your selected collection method. If you are using a connection that streams the data (Bluetooth-LE, Serial, etc) then the Data Studio will automatically save the file to your local hard drive and upload it to the cloud

  1. (Optional) You can create labels in your file during data collection by using the Live Labeling feature. Live Labeling lets you label your events in real-time during data collection. Click the + button on any label to add a label to your file
