# atom-s3-co2
CO2 monitor integration for M5Stack AtomS3. Reads sensor values from [UD-CO2S](https://www.iodata.jp/product/tsushin/iot/ud-co2s/), and sends values to ThingsSpeak IoT platform. Temperature, Humidity (relative and absolute), CO2 concentration are shown in the display. Click on the display button to switch between each readings.
## Materials
- M5Stack AtomS3
- [UD-CO2S](https://www.iodata.jp/product/tsushin/iot/ud-co2s/)
- USB AC adapter (Type A)
- [USB Type A male to male cable](https://www.amazon.com/dp/B00HSS9KJY)
- [USB Type A splitter](https://www.amazon.com/dp/B085BJRZN2)
- One female end connects to power
- One female end connects to UD-CO2S
- Male end connects to Atom S3, using Type C to A adapter
- [USB Type C (male) to A (female) adapter](https://www.amazon.com/dp/B0C9VD4YTK)
- Used to connect AtomS3 to USB splitter
- [USB Type C Extender Adapter](https://www.amazon.com/dp/B0D9XHNDX6)

## Setup
- Prepare environment: VSCode + platform.io
- Setup `src/config.h`
- ThingSpeak API keys, channel ID, data sending interval
- Wi-Fi SSID and password
- Build and write the program to AtomS3 using USB
- Connect UD-CO2S to AtomS3
- Provide power 5V supply
- When AtomS3 is booted up, it will automatically connect to Wi-Fi and start reading values from the sensor.
