Welcome to the future of airflow sensing. SONIC-1 is a bidirectional ultrasonic airflow sensor system designed for rugged environments like tunnels and underground mines. This guide gets you started in minutes â no calibration, no fuss, just real-time airflow intelligence.Â
đ§ Mounting Geometry
Position: Install transducers across the tunnel on opposite walls.
Position: Install transducers across the tunnel on opposite walls.
Height: Typically one near the ceiling, the other downstream near the floor to sample the full cross-section
Height: Typically one near the ceiling, the other downstream near the floor to sample the full cross-section
Angle: Face each other at 30â60 ° to flow (sweet-spot â 45 °) for optimal results.Â
Angle: Face each other at 30â60 ° to flow (sweet-spot â 45 °) for optimal results.Â
Distance: Ideal range up to 18m (60ft); practical maximum tested at 20m (65ft) , Baseline (hypotenuse) auto-rangesâno tape-measure entry needed.

Mounting Tip: Â Find a straight tunnel segment at least 3 tunnel-widths long.
Avoid: Corners or areas where airflow hugs the walls; centerline flow should dominate.
đ Power Up & Network DiscoveryÂ
đ Power Up & Network DiscoveryÂ
Power Requirement: 24VDC @ 200mA (4.8W total system). / 120-220V ACÂ
Default Network Mode: DHCP-enabled â device automatically requests an IP from your router.
đ ïž Finding Your Device Â
đ ïž Finding Your Device Â
Option A: Use your networkâs DHCP lease table to find the assigned IP.
Â
Option B: Use the PA Discovery Tool (PADisco):
padisco --find
Option C: Configure IP manually:
Insert a microSD card.
Open system.jsn file.
Enter static IP settings:
"ipv4": {
  "dhcp": false,
  "ip": "192.168.1.50",
  "mask": "255.255.255.0",
  "gw": "192.168.1.1"
}
Insert microSD card into device and reboot.

No need for manual calibration or baseline input.
True auto-ranging calculates the distance between transducers automatically.
Two signal detectors: choose between high-precision or noise-resistant filtering depending on your environment.
