Anyone using this device to measure VOC/CO2?

I am using this one (has basically the same sensor inside):

Measurements are highly dependent on temperature/humidity/aging!
Reproducable results are impossible!
GOOD LUCK compensatin it
If you have extreme situations like smoke in a room or a used toilet, the sensor MIGHT give you a short term realiable signalling; but do you wanna correct the threshold every month again? -NO! So don't waste your money and time with it.
I can absolutely NOT recommend these sensors.

Then the SenseAir S8 could be an option (75 euros)

Or we wait till Q1 2017 for the Bosche BME680 VOC sensor: http://www.uradmonitor.com/bosch-bme680/

I also find this one: MICS-VZ-89F http://www.sgxsensortech.com/content/up ... -rev-6.pdf
