   Hello Fedi, 💗

   Do you know anything about *indoors air quality measurement*? 💨 📈

   A few questions here:

   - is the "Air Gradient One" truly one of the most exhaustive + affordable option (respectful of people's computing freedom? https://www.airgradient.com/indoor/ Or is there something better?

   - is that precise enough that you could move in a space and identify sources of particles? (stashes of devices, windows, carpets, etc?)

   - how about mold? is there any DIY solution for those?

     @stf nice, but what type of sensors? (i could RTFM this...)

     As you can see on https://www.airgradient.com/shop/#!/AirGradient-ONE-Indoor-Monitor-Pre-Soldered-Kit-Version-9/p/594725501/category=155176011

     the AirGradient One has a
     Sensirion SGP41 TVOC/NOx Sensor, a Plantower PMS5003 PM sensor, etc. ... and those are a bit pricey, and chunky. I am pretty sure i would have noticed similar beasts on the Rad10.

     If by "air quality" we mean just CO2 and humidity, yeah there are tons of cheap things for that.

     I am wondering about thin particles and specific pollutants, and also molds...

     @jz if you have a rad1o it can do air quality measurements, i can provide you with an app, that dumps this on the serial port over usb, but i'm sure it's easy to also show it on the display.
