## Questions & Answers

**Q: I am looking for a radon gas detctor module, will any of these work for that?  Which one?**
A: No. you  need to look for specific devices here to detec that. Radon is an radioactive element not molecule.

**Q: Which of these sensors detect ammonia?**
A: There is a mark under each sensor, you can distinguish according to the mark

**Q: What does the m135 air quality sensor detect? Specifically?**
A: The MQ-135 Gas sensor can detect gases like Ammonia (NH3), sulfur (S), Benzene (C6H6), CO2, and other harmful gases and smoke. So basically it will give you values in ppm for these gases I mentioned. It is not very specific as you may see.
