AIR QUALITY METER
=================
Goals:
-----
* DIY (you can modify it and improve it)
* Low cost equipment
* Easy and cheap replace of sensors
* Comprehensible air quality level indicator (good-green, fair-yellow, bad-red)
* History records
* Graphics
* Portable (battery included)
Hardware (first version):
------------------------
* [M5Stack Core2 ESP32 IoT Development Kit](https://docs.m5stack.com/#/en/core/core2?id=m5core2)
* Temperature, humidity & barometric pressure sensors: [ENV II Unit with Temperature Humidity Environment Sensor (SHT30+BMP280)](https://docs.m5stack.com/#/en/unit/envII?id=env-ii)
* NDIR CO2 Sensors: Sensirion SCD30, SenseAir Sunrise
Software to compile:
-------------------
[Visual Studio Code](https://code.visualstudio.com/) + [PlatformIO](https://platformio.org/install/ide?install=vscode) (arduino libraries, ESP32 SDK)
Progress:
--------
* Publish first version
* Realtime data in text mode [done]
* Webserver [done]
* JSON output [done]
* Save history records
* New: Add LVGL library to improve interface (GUI)
* New: Include history graphics
* New: MQTT integration
* New: Home Assistant integration
Considerations for CO2 Sensor:
-----------------------------
* Readings each 1 or 2 minutes for battery powered devices.
* Calibration according to manufacturer CO2 sensor (minimum 20 minutes outdoors, avoid to be near persons, vehicles and other contaminants)
* Lifetime of NDIR CO2 sensors: 5, 10 or 15 years.
