## Questions & Answers

**Q: Is it work with Raspberry Pi? Is there any tutorial?**
A: Dear Fahad, Thanks for contacting us. This product comes from DFRobot and not R-Pi so they may or not support interconnection directly. Which means to say that electronically they could be made to work together, but it would be up to you to make the necessary interconnections. If you go to this link: https://www.jameco.com/z/SEN0159-DFRobot-CO2-Sensor-Arduino-Compatible-_2213270.html
and in the middle column you will see that there are numerous links for schematics, data and coding. From there you could determine if this will work in your case. - Greg

**Q: Hi, does this sensor need to be calibrated? Do I need special equipment if so?**
A: Yes， it need to preheat in the fresh air for 24 hours, you can see the calibration method in wiki. https://www.dfrobot.com/wiki/index.php/CO2_Sensor_SKU:SEN0159#Calibration

**Q: Range of item? Like from how many ft to how many ft?**
A: Hi Wiley,  the detect range is between 350 to 10,000 ppm (parts per million).  It only measures the air around it.  Let me know!

**Q: I am a senior working on my final project and i was wondering if this item is compatible to work with labview myrio edition 2017?**
A: Most of our customers use the compatible Arduino and have installed Arduino software and drivers on Windows 10 - based computers.
Labview Myrio 2017 should work well with this CO2 Gas Sensor .

## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome Sensor!
*by B***E on January 27, 2019*

This is an incredibly accurate and powerful sensor. They've even gone so far as to include a heating coil to make sure measurements always occur at the same temperature. The chip is well designed and they've definitely put a lot of care into making a quality board.I was a bit concerned by reading the other reviews, but after doing a small amount of calibration work (read the Questions section to find out how to calibrate - it's pretty simple), I was able to get this sensor working very well.Because of the heating coil, the sensor can get quite hot, but it's worth it to get more accurate readings. Overall, I would highly recommend this sensor, especially since it's so cheap!

### ⭐⭐ Unclear breakout, bad docs, poor datasheet, worse sample code. Order an NDIR instead and be happier
*by A***X on January 8, 2016*

I want to give this item three stars because the PCB and components are high quality and care was obviously given when designing this unit. HOWEVER....read on for my rationale behind this two star flop.Poor available documentation and datasheet available for this mg-811 breakout. Datasheet displays a completely different sensitivity curve than is actually detected by the sensor.Placed unit in 3000ppm co2 calibrated gloved box and it continually floats to lower voltages over two weeks time despite no additional co2 being introduced to environment. Sensor fluctuates despite consistent ambient temp/humidity and adequate warming unit temperature.Supplied code is so inaccurate it is unusable. Factory uncalibrated and frustratingly floats through baseline calibration algorithms that work for other co2/gas sensors. My NDIR sensors are far more reliable, calibrate on algorithm properly and only cost about 10 dollars more...look around and you'll find them. Good luck to all those others seeking accurate environmental co2 readings.

### ⭐⭐⭐ Three Stars
*by A***R on August 31, 2018*

Must include calibration kit, otherwise you don’t really know what are the meaning of the readings.
