IAQ Board is a DIY device for measuring internal air quality running with esphome. It's quite small and is based on a custom PCB where part of the components are soldered and connected.
|
||
|
|
|
||
|
|
Here is what it can measure:
|
||
|
|
|
||
|
|
- **Temperature / Humidity / Pressure**
|
||
|
|
- **Air particles PM1, PM2.5, PM10**
|
||
|
|
- **Carbon Dioxide with NDIR sensor**
|
||
|
|
- **Air Quality Index by EPA, based on 24h average PM2.5 particles**
|
||
|
|
- **Ambient light**
|
||
|
|
- **Total VOC (volatile organic compound)**
|
||
|
|
- **equivalent CO2 (not very correct compared with the NDIR sensor, but it's provided by the VOC sensor)**
|
||
|
|
|
||
|
|
On top of that:
|
||
|
|
|
||
|
|
- **At least one OLED display to show the data (can have one more on the top of the MCU board)**
|
||
|
|
- **three RGB wide angle LEDs with auto brightness. LED1 indicates PM2.5, LED2 - Air quality index, LED3 - CO2.**
|
||
|
|
- **auto night dimming of the displays and LEDs (can be disabled)**
|
||
|
|
- **MIN/MAX values of Temperature, PM2.5 and CO2, and 24h average PM2.5 value.**
|
||
|
|
- **multi function button for selection of the data to show on the display**
|
||
|
|

ESPHome Configuration
|
||
|
|
---------------------
|
||
|
|
Full documentation (PCB, Schematic, esphome yaml config) is published here: `https://github.com/nkitanov/iaq_board <https://github.com/nkitanov/iaq_board>`__
|
||
|
|
|
||
|
|
YAML configuration is about 700 lines and can be downloaded from here: `iaq_board.yaml <https://github.com/nkitanov/iaq_board/blob/master/firmware/iaq_board.yaml>`__
