Hi Wouter,

There is an IKEA PM2.5 sensor in the space you could take home to check out your air quality (doesn’t do CO2 but still could be interesting). It is one of these: https://www.ikea.com/gb/en/p/vindriktning-air-quality-sensor-80515910/ 

If you don’t find anything for CO2 then remind me before next Tuesday to bring along the sensor from the office. It does CO2, PM2.5 and VOC and shows you the numbers and a happy/sad face. You could borrow that for a couple of weeks.

Iain.

hi folks,

I have a suspicion my home office does has issues with CO2 accumulation when windows/doors are closed, which makes me sleepy.  It is that, or my work is not challenging enough ;-)   

To rule out the latter, I would like to test the indoor air quality for a couple of days.  Has anyone got perhaps an unused CO2 sensor lingering about, or Chinese rip-off of the SCD-40 sensor, that I could use for a couple of days?

Cheers,
Wouter   (Aberdeen)
