How WII5 buoys talk — Iridium for over-the-horizon, local channels for in-the-field configuration.
Category: Features
Iridium
Over-the-horizon satellite uplink using Iridium short-burst-data.
Categories:
MPPT
Solar charging via MPPT — maximum power point tracking. Custom-designed for the small batteries used in solar WII buoys, because nothing off-the-shelf fit.
Categories:
Waves
Wave-statistics calculation — significant wave height, peak period, energy.
Categories:
Calculations
On-board calculations — wave statistics and directional analysis.
Categories:
Direction
Directional wave-spectrum analysis from accelerometer + GPS heading.
Categories:
GPS
GPS — position, time, and directional heading.
Categories:
Local
In-field local channels — BLE, serial, and Wi-Fi for configuration and read-out.
Categories:
Kistler
Kistler high-precision accelerometer for wave-motion measurement.
Categories:
Sensors
Sensors carried by WII5 buoys — power, navigation, motion, environment, imaging.
Categories:
IMU
Inertial measurement unit — accelerometer, gyroscope, magnetometer.
Categories:
Temperature
Water and internal temperature sensing.
Categories:
Anemometer
Wind speed and direction sensor.
Categories:
Cameras
Visual deployment and surface-imaging cameras.
