Data Collection:
- Use a USB-C cable to plug an Observe sensor into your computer's USB port.
- Click Connect Sensor to connect the first sensor.

- Alternatively, add measurements one at a time by pressing Add Point. You will be prompted for an x-value for each measurement. Once Add Point is used, time-based collection is disabled until the page is refreshed.
- Clear Graph resets the graph; Capture Graph copies an image of the graph to the clipboard; Export/Import saves or opens a CSV data file.
- Click the small gray triangle to the left of the data table to view time (t) or event values along with the sensor data (y₁ and y₂). The y₂ column appears only when a second sensor is connected.
