DIY Pro kit presoldered strange TVOC readings (strange peaks)

Good day! I’m experiencing some quite a strange TVOC sensor readings. I do not see any pattern… Is it sensor malfunction or I need to evacuate from my house asap? ;]

I tried to put DIY kit in two different rooms, but strange behaviors’ continued.

A few more pictures

Can you post some charts for PM, CO2, temp and humidity for the same time frame?

Here is today’s measures. I moved the DIY Prokit 2m away closer to the open door… But peaks are still present

I can give you an example I experienced with TVOC. When the sun shines on my wooden floor some volatile compounds or odours are getting released. Then the sensor peaks a bit but will go down as soon the sun moves away. Maybe the sun is causing it in your circumstance. You could also try to move the sensor outside for a while to see if TVOC goes down.(Assuming your not living in highly industrial area)

We can see the correlation between CO2 and TVOCs

Humans exhale VOCs

“The medical community has long recognized that humans
exhale volatile organic compounds (VOCs). Several studies
have quantified emissions of VOCs from human breath,
with values ranging widely due to variation between and
within individuals.”
