Powered by a stable 5V DC source, it features dual analog and TTL outputs with a visual indicator light for instant alerts. Designed for quick response and long-term reliability, this kit is perfect for environmental monitoring and safety projects, delivering precise gas concentration readings from 10 to 1000ppm in a compact, easy-to-mount form factor. ## Description Description: With signal output indicator light. Working voltage: DC 5V; With signal output indicator light; The dual signal output (analog output and TTL output); The analog output and increased with the increase of concentration, the higher the concentration higher voltage; Has a very high sensitivity to sulfide, benzene vapor, smoke and other harmful gases; With a long service life and reliable stability; Quick response and recovery characteristics; With mounting holes, easy mounting; The probe can be plug design, convenient test Application: For harmful gas family, environment detection device, is suitable for the detection of the ammonia, aromatic compounds, sulfide, benzene vapor, smoke and other harmful gas, gas sensitive element concentration range: 10 to 1000ppm provides reference cases. Package List: MQ-2 Smoke Sensor MQ-3 Alcohol Sensor MQ-4 Methane Sensor MQ-5 LPG Natural Gas City Gas Sensor MQ-6 isobutane propane sensor MQ-7 Carbon Monoxide Sensor Module MQ-8 hydrogen sensor MQ-9 Carbon Monoxide Combustible Gas Sensor MQ-135 air quality detection sensor If for whatever reason, you decide you are not satisfied. You can easily and quickly contact our helpful customer support and get an easy refund. Any questions about our item, please feel free to contact us. Your satisfaction is our pursuit Review: Neat set of useful gas sensors - 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. Review: Not too thrilled - 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 desertcart picture. What kind of Rinky Dink outfit is this. Kind of disappointed ## Features - Working voltage: DC 5V; With signal output indicator light; - With a long service life and reliable stability;Quick response and recovery characteristics; - The analog output and increased with the increase of concentration, the higher the concentration higher voltage - For harmful gas family, environment detection device, is suitable for the detection of the ammonia, aromatic compounds, sulfide, benzene vapor, smoke and other harmful gas, gas sensitive element concentration range: 10 to 1000ppm provides reference cases. - Package Includes: MQ-2 Smoke Sensor,MQ-3 Alcohol Sensor,MQ-4 Methane Sensor,MQ-5 LPG Natural Gas City Gas Sensor,MQ-6 isobutane propane sensor,MQ-7 Carbon Monoxide Sensor Module,MQ-8 hydrogen sensor,MQ-9 Carbon Monoxide Combustible Gas Sensor,MQ-135 air quality detection sensor ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07D9H74LT | | Alarm | Visual | | Best Sellers Rank | #377,446 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #29 in Lab Gas Handling Instruments #206 in Gas Detectors & Alarms | | Brand | BAITHNA | | Color | blue | | Customer Reviews | 4.1 4.1 out of 5 stars (36) | | Manufacturer | BONATECH | | Mfr Part Number | BONATECH-004 | | Model Number | 8541582913 | | Power Source | Battery Powered | | Product Style | Modern | | UPC | 634759567974 | | Unit Count | 1 Count | ## Product Details - **Alarm:** Visual - **Brand:** BAITHNA - **Color:** blue - **Manufacturer:** BONATECH - **Power Source:** Battery Powered - **Style:** Modern - **UPC:** 634759567974 ## Images ![9 in 1 MQ Sensor Modules Kit Project Super Starter Kits for Gas Detection - Image 1](https://m.media-amazon.com/images/I/71g2xGPK4xL.jpg) ## 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 T***T on January 17, 2024* This is a nice array of gas sensors.
