OzWrapper.OzNoise.OzNoise

Noise level sensor wrapper (v1).

This module provides OzNoise, the first-generation noise-level sensor wrapper for Oizom environmental monitors. It communicates with a SAMD-based co-processor over UART (via the drivers.OzLan.OzLan.OzLan driver) to read ambient sound pressure level measurements - equivalent continuous level (Leq), maximum (Lmax), and minimum (Lmin) - reported in dBA SPL through the SensorBase.SensorBase.GenericSensor contract.

Reference config:

{
  "noise": [
    {
      "en": 1,
      "pn": 41,
      "gpio": {
        "baud": 115200,
        "port": "/dev/ttyACM0"
      },
      "parameters": [
        {
          "cr": 0,
          "pm": 1,
          "sc": "leq",
          "se": 100
        },
        {
          "cr": 0,
          "pm": 2,
          "sc": "lmax",
          "se": 100
        },
        {
          "cr": 0,
          "pm": 3,
          "sc": "lmin",
          "se": 100
        }
      ]
    }
  ]
}

Example

Instantiate the wrapper and initialise the sensors declared in the Gateway configuration:

>>> from OzWrapper.OzNoise.OzNoise import OzNoise
>>> noise = OzNoise()
>>> init_state: dict = {}
>>> noise.initialize(config["noise"], init_state)
True

Note

This is the legacy v1 implementation built around a single SAMD microphone front-end. For newer deployments that expose octave-band metrics and improved diagnostics, prefer OzWrapper.OzNoiseV2.OzNoiseV2.OzNoiseV2.
