# CO2 Sensor

## What

Use Arduino Nano 33 IoT, a CO2 sensor and a OLED display for displaying the current CO2 concentration.

The current vaue should also be exposed via http.

Stretch goal is to connect this to a openHab smarthome and show graphs in Grafana and trigger alerts for high values.

## Why

I want to know for how long I need to open windows in the morning to get fresh air into my house, without losing too

much heat in winter. Bonus: in the current situation something like this might be used as an indicator for the need

for fresh air for reducing the Coronavirus concentration.

## How

### Parts

- Arduino Nano 33 IoT

- Sensirion SDC30 CO2, humidity and temperature sensor module

- Waveshare 0.95 inch RGB OLED

### Some hints

- https://tinygo.org/microcontrollers/arduino-nano33-iot/

- for IntelliJ:

    - see https://medium.com/@brandentimm/arduino-development-with-tinygo-in-jetbrains-ides-f29dbf5da675

    - and disable module support in the project!
