## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Neat set of useful gas sensors
*by  on Reviewed in the United States January 17, 2024*

This is a nice array of gas sensors. It's a shame they included no documentation whatsoever, but on the plus side, they're extremely easy to use and set up. Connect the 5V and ground pins. Then, you have the option of using the analog or digital out for readings. I prefer to use the analog output when feasible. An LM393 comparator is used to convert the analog signal to digital logic for the digital output and this can be adjusted with the potentiometer. I hope these hold up over time, I'll be using them in some outdoor projects.

### ⭐⭐⭐ Not too thrilled
*by  on Reviewed in the United States August 2, 2024*

I did not test the Sensors yet so the quality is unknown. I am in the process of building a PM2.5 Particulate Matter Sensor. My problem is the poor shipping, they were all jammed in this little box. Most of the sensor metal screens were all bent up. Two of the sensors were not labeled. Now I have to guess at the sensor type. One has a housing that is not even in the Amazon picture. What kind of Rinky Dink outfit is this.Kind of disappointed

### ⭐ Out of 9 only 4 working
*by  on Reviewed in the United States August 13, 2024*

Poor soldering is visible. Tried to fix, but only 4 out of 9 working.
