## M5CoreInk / M5StickC CO2 Sensirion sensor hat Source code and 3DPrint files for making a CO2 hat for M5CoreInk/M5StickC (or any ESP32 compatible board), this use a Sensirion SCD30 sensor for get CO2 values. ## Components | Description | Store link | |----------------------------|-------------------------------| | M5CoreInk |[M5Stack](https://m5stack.com/collections/m5-core/products/m5stack-esp32-core-ink-development-kit1-54-elnk-display) | | M5Stack Proto | [M5Stack](https://m5stack.com/collections/m5-core/products/m5stack-esp32-core-ink-development-kit1-54-elnk-display) | | Sensirion SCD30 | [Mouser](https://eu.mouser.com/ProductDetail/Sensirion/SCD30/?qs=rrS6PyfT74fdywu4FxpYjQ%3D%3D) | | | | M5StickC (compatible) | [M5Stack](https://m5stack.com/collections/m5-core/products/stick-c) | M5StickC Plus (compatible) | [M5Stack](https://m5stack.com/collections/m5-core/products/m5stickc-plus-esp32-pico-mini-iot-development-kit) | | | ## How to build it <iframe width="560" height="315" src="https://www.youtube.com/embed/im0LNFRrHCg" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> ## Firmware upload First of all, install PlatformIO with your favourite IDE (i.e. VSCode). Follow [this](https://platformio.org/platformio-ide) instructions. Also, you may need to install [git](http://git-scm.com/) in your system. [source code](https://github.com/hpsaturn/co2_m5coreink) ### Clone the repo ```sh git clone https://github.com/hpsaturn/co2_m5coreink.git ``` ### Via IDE (vscode) Connect the M5CoreInk or compatible board via USB. In Windows 10, drivers are installed automatically. I guess with other OS will be automatically installed too. Open cloned folder with your PlatformIO IDE and build & upload it. For details please see the [documentation](https://docs.platformio.org/en/latest/integration/ide/vscode.html#quick-start), but the process flow is more easy than Arduino IDE flow, but you can also import it to the Arduino IDE if you want.  ### Via PlatformIO CLI After the clone, enter to directory and you can build and upload the current firmware from CLI: ```shell pio run --target upload ``` # 3D print Files <a href="https://github.com/hpsaturn/co2_m5coreink/tree/master/box" target="_blank"><img src="https://raw.githubusercontent.com/hpsaturn/co2_m5coreink/master/images/3Dpreview.jpg"></a>
