Architecture Overview
=====================

Entry Point
-----------

The application starts from :mod:`main`, which creates a :class:`Sensor.Sensor.Sensor`
instance and calls ``setup()`` followed by ``loop()``.

.. automodule:: main
   :members:

Configuration
-------------

Device configuration is loaded from two sources:

1. **Static config** -- ``Configuration/config.json``, loaded by :class:`Configuration.config.Config`
2. **Dynamic config** -- Fetched from the Gateway at startup via :class:`Manager.Manager.Manager`

Sensing Loop
------------

The main loop in :meth:`Sensor.Sensor.Sensor.loop` performs these steps each cycle:

1. Read all enabled sensors via their wrapper's ``getSensorReading()``
2. Average readings over the configured interval
3. Compute derived indices (WBGT, dew point, etc.)
4. Post data to Gateway via :meth:`Manager.Manager.Manager.sendData`
5. Send realtime data via :meth:`Manager.Manager.Manager.sendRealtimeData`

Communication Threads
---------------------

Several communication interfaces run in background threads:

- **Network** -- Continuous internet connectivity check
- **WebSocket** -- Realtime data push to dashboard
- **Modbus** -- Async sensor polling on the Modbus bus
- **LoRa** -- Long-range radio communication
- **Sigfox** -- LPWAN communication
- **HMI** -- 7-segment display updates
