Stack only WeatherStation

Overview

Simple embedded application for environmental sensing and reporting implemented in modern C++17 for small microcontroller boards. The project collects temperature, humidity, pressure, light, soil moisture, and ultraviolet intensity then formats measurements as JSON for downstream consumption.

No dynamic memory is used: everything lives on the stack ensuring forever uptime!

Repository Layout

1. platformio.ini Configuration for build targets and board definitions
2. include Public header files used across modules
3. lib Libraries organized per feature
   1. JsonStreamer Lightweight JSON output helper
   2. MeasurementBuffer Ring buffer for sample storage
   3. Sensors Sensor abstractions and device specific code
   4. TaskManager Cooperative task scheduler utilities
   5. Utils Small helper templates and logging utilities
4. src Application entry point main.cpp

Build and Run

Use the PlatformIO integration in the editor to build and to upload firmware. The project defines an environment named uno intended for AVR UNO class boards. Build from the editor tasks or from the PlatformIO user interface.

Configuration

Edit platformio.ini to change board settings or to add new environments. Sensor wiring and hardware specific constants are declared in include/constants.h and in the sensor headers under lib/Sensors.
