Which sensors can be used to detect paint ?

Other Hardware Sensors

Hello to everyone.I posted about 2 months ago that I wanted to know are there 12V versions of MQ2 and MQ135 sensors.I tried both of them and they don't react at all with paint.I am not sure if it matters but I didn't let them sit alone 48h(at shop no one told me about preheat time plus I didn't have idea) only few minutes and after that I tried testing them.Are they damaged or they can't just detect paint fumes ? Thanks for reply.

Verify with the manufacturer specifications on warm up and power requirements.

Other choices seem to be (search: arduino voc)
CCS811
MP503
SGP30
SGP40

Thanks for reply and sorry for late answer.I was busy.I will try them.Also does arduino support running multiple sensors at once ? I have one MQ2 and two MQ135 and I want to use them at the same time.

I found that CCS811 is fine.Thanks to everyone.I want to ask is it possible to use CCS811 with GSM module which will send a message if TVOC is greater than for example 20000 ??
Thanks
