To add to the list of sensors: I was most curious in CO2 levels, so I got an Aranet4: https://www.amazon.com/dp/B07YY7BH2W/ref=cm_sw_r_cp_api_glt_fabc_68MQ94BWJ

It’s got an eink screen, and I haven’t had to recharge it since I got it 8 months ago. I really like it.
- Robotbeat 5y agoAre there any affordable CO2 sensors that don’t use outside air for calibration of ppm? I want to know how outside air CO2 levels change as well. Would be interesting to see day to day changes and how big they are in absolute terms. (Also to show people about how CO2 levels are changing globally… without just pointing to a website of someone else’s measurements.)
