CO2, CO and PM measured every 2 seconds, indoors. These are raw sensor data, and we need to remove the noise, and calculate concentration.
Readings need about 2000 seconds to stabilize... so our device will be portable, but will not be exactly mobile:(
After nearly 6000 readings, window was opened. Breeze of fresh air is clearly visible - readings display less monoxide, dioxide and dust:)
Battery dies after about 19000 seconds, and readings are inaccurate soon before.
