Found the IKEA Air Quality Sensor
@rastinza Good question ... I'll need an expensive sensor I guess 🤔
@lupyuen In my city there are sensors to measure the quality of the air, and they publish the data online daily.
You could go nearby the area of one of such sensors, write down the reading of yours and wait for them to publish the data.
Do this a few times and you should see if it works decently.
@rastinza Thanks for the tip! Will try that 👍
@lupyuen That's great!
How will you measure the accuracy?
