Here are the biggest questions on my mind right now (let me know if you have thoughts)! #electronics
- How could I make the device cheaper? The Sunrise CO2 sensor costs 50 EUR per piece. The other components will be really cheap, but I need a good, low-power sensor. The SCD41 is cheaper, but draws an average of 450 uA (compared to the 16 uA of the Sensair).
- How could I minimize the power/time for refreshing the e-ink display? Use a smaller screen? Use a Memory LCD instead?
