Sensor fusion framework for Elixir built on OTP.

Poll sensors at configurable intervals, buffer readings, fuse data with weighted averaging and configurable thresholds, and render real-time HUD widgets (gauges, sparklines, threat indicators, minimaps).

Quick Start

defmodule CpuSensor do
  @behaviour Raxol.Sensor.Behaviour

  @impl true
  def read(_opts) do
    # Return a sensor reading
    {:ok, %Raxol.Sensor.Reading{
      sensor_id: :cpu,
      value: get_cpu_usage(),
      unit: :percent,
      timestamp: System.monotonic_time(:millisecond)
    }}
  end
end

# Start the sensor supervisor, then register sensors
Raxol.Sensor.Feed.start_link(sensor: CpuSensor, interval: 1000)

Architecture

• Raxol.Sensor.Behaviour -- Sensor callback and Reading struct
• Raxol.Sensor.Feed -- GenServer: polling, buffering, error escalation
• Raxol.Sensor.Fusion -- GenServer: batching, weighted averaging, thresholds
• Raxol.Sensor.HUD -- Pure functional HUD widgets (gauge, sparkline, threat, minimap)
• Raxol.Sensor.Supervisor -- rest_for_one: Registry + DynSup + Fusion

Optional Nx Backend

When {:nx, "~> 0.9"} is available, vectorized fusion operations use Nx tensors for batch processing sensor readings.
