ParaBaro User Manual
Paragliding Wing Pressure Monitoring System
Firmware v7.0
ParaBaro monitors your paraglider wing's inflation pressure in real time using four wireless BLE sensors. It detects partial collapses, records your flights with GPS tracking, and uploads data to the cloud for post-flight analysis. The system is designed for research, training, and building a deeper understanding of wing behaviour.
You will also need a FAT32-formatted microSD card (max 32 GB, not included).
Connect the USB-C cable. A full charge takes 2–3 hours and provides 6–8 hours of continuous use.
Each transmitter uses a CR2032 coin cell (or CR2450 for extended life). Expected battery life: 17+ months (CR2032) or 48+ months (CR2450).
With the receiver powered off, insert a FAT32 microSD card into the side slot. This stores your flight recordings.
Visit aviometrics.com/register to create your pilot account and enter your wing details.
Press the power button for 1 second. The receiver boots in 5–10 seconds. Go to Settings and tap Pilot Dashboard to pair with your web account via BLE.
The Flight screen after power-on — sensors not yet connected (grey LEDs).
The ParaBaro receiver has three main screens. Swipe or tap the navigation buttons to move between them.
Flight Screen
Settings Screen
Flights Screen
From the Flight Screen, tap SET » to enter Settings. From Settings, tap FILES » to view your recorded flights, or « BACK to return to the Flight Screen.
This is the main screen you'll see during flight. It shows real-time wing pressure, GPS data, and flight statistics.
The teal header bar shows the current time, date, GPS satellite count, WiFi status, and battery level. The GPS icon turns green when you have a satellite fix.
Four indicator bars sit below the header — one for each pressure sensor: LIn (Left Inner), LOut (Left Outer), RIn (Right Inner), ROut (Right Outer). They turn green when the sensor is connected and transmitting data.
The two semicircular arcs are the core of ParaBaro. The left arc shows combined left-wing pressure; the right arc shows the right side. They fill from the bottom upward as pressure increases, and change colour based on inflation level:
The green circular button in the centre of the arcs is used for calibration. Press and hold for 1.5 seconds to start a 10-second calibration cycle. It turns orange during calibration.
Around the arcs you'll see four flight instruments in yellow: flight time (top left), distance (top right), speed (bottom left), and altitude (bottom right). These update live from the GPS receiver.
REC starts and stops flight recording. It turns red while recording. SET » opens the Settings screen.
Recording — REC button turns red
Calibrating — CALIB turns orange
Displays your pilot name, wing model, and device ID. These are synced from your web dashboard via BLE when you pair the device.
Shows the current WiFi connection. When connected (green), you can upload flights directly from the device.
WiFi connected — ready to upload flight data.
The Settings screen has five buttons arranged in two rows:
The Flights screen shows all recorded sessions stored on the SD card. Each entry displays the flight date/time and upload status for both file types:
Connect to WiFi (configured via web dashboard), then tap UPLOAD. The device will batch-upload all pending IGC and CSV files to your aviometrics.com account. You can also delete individual flights using the red × button on each entry.
flight_YYYYMMDD_HHMMSS.csv and flight_YYYYMMDD_HHMMSS.igc.
Calibration establishes a baseline pressure reading so the device knows what "zero inflation" looks like. You should calibrate before your first flight of the day and whenever readings seem off.
Ensure the wing is on the ground and the sensors are in their mounting positions. No airflow should be pressurising the cells.
On the Flight Screen, press and hold the green CALIB button for 1.5 seconds. It turns orange to confirm.
Keep everything still for the 10-second calibration period. The device records baseline readings from all four sensors.
After calibration, the arcs should show near-zero values and the CALIB button returns to green. You're ready to fly.
Calibration in progress — CALIB button turns orange, countdown shown.
calibration_YYYYMMDD_HHMMSS.csv) is saved to the SD card each time. This is useful for diagnostics and quality control.
Tap the REC button on the Flight Screen. It turns red to indicate recording is active. Two files are created simultaneously:
REC button turns red during active recording.
Tap REC again to stop. The button returns to teal and the files are finalised on the SD card.
Files are named with the recording start time: flight_20260217_143500.csv and flight_20260217_143500.igc.
The inflation arcs use an aviation-standard colour coding system (compliant with FAR 25.1322) to give you instant visual feedback on wing state.
Green — Normal (> 40 Pa)
Amber — Caution (20–40 Pa)
Red — Danger (< 20 Pa)
The four BLE pressure sensors are positioned on the inside of the wing to measure internal cell pressure. Correct placement is essential for accurate readings.
Sensors attach magnetically and should be positioned between 20° and 90° from the leading edge. They use ambient light detection to activate automatically when the wing is opened.
Log in at aviometrics.com to access your pilot dashboard:
On the Settings screen, tap Pilot Dashboard to put the device in BLE pairing mode. Then, on your computer or phone, visit your pilot dashboard in Chrome or Edge, go to the Device tab, and click Connect. Select your ParaBaro from the Bluetooth list. Once paired, your pilot name, wing model, WiFi credentials, and RTC time will be synced to the device.
| Issue | Solution |
|---|---|
| Sensors won't connect (LEDs stay grey) | Power cycle both receiver and sensors. Ensure sensors are within 10 m. If still failing, go to Settings and tap Reset Sensors to clear pairings, then re-pair. |
| Only some sensors connect | Check the coin cell battery in the affected sensor. Ensure the sensor is exposed to light (ambient light sensor activates BLE advertising). |
| SD card not detected | Use a FAT32-formatted card, maximum 32 GB. Ensure the card is fully inserted. Try reformatting the card on a computer. |
| GPS shows "0" satellites | Ensure clear sky visibility. The first fix after power-on may take 1–2 minutes. GPS works best outdoors with an unobstructed horizon. |
| Touch screen unresponsive | Power cycle the receiver (disconnect USB, wait 5 seconds, reconnect). If persistent, check that the screen is clean and dry. |
| Clock shows wrong time | Sync time via the web dashboard Device tab. The RTC has battery backup and should maintain time between sessions. |
| Upload fails | Check WiFi connection (green WiFi icon in header). Ensure battery is above 20%. Verify your WiFi credentials via the web dashboard. |
| Pressure readings seem wrong | Run calibration with the wing flat on the ground. Values should read near 0 Pa after calibration. |
| BLE pairing won't start | Ensure you're using Chrome or Edge (Web Bluetooth is not supported in Firefox or Safari). The device must be on the Settings screen with Pilot Dashboard tapped. |
| Firmware update fails | Ensure stable WiFi and battery above 50%. Tap Update Firmware again to retry. Do not power off during an update. |
