- Hi All, today, im showing you how to setup and Code a MQ135 CO2 Sensor this will give an estimated measure of the PPM (parts per million) in the air.
I am using the MQ135 CO2 Sensor along side with a Arduino Mega but you can use any board you like as long as it has analogue inputs.
This sensor is designed to be used in my Algae Co2 Scrubber check out those videos as well

awesome channel, scotty! I'd love to get an update on the CO2 scrubber project.
Hey, thanks. I did a community post as to where the videos for the system is currently at. And what videos are coming up. I’ve been trying to put together a few videos at the moment hopefully releasing soon.
Hello, thank you for the video, i was wondering if there could be any diference in the values that you get using the mq135 rather than the Mg811 co2 sensor?, or which could be the differece?, i appreciate your help, thanks a lot, best regards
really i want to tell...
your presentation and communication Excellent....
keep moving......
Got a quick question scotty,
my values that I get are around 950ppm altough I'm using the same code and same connections as you do. Do you have any idea why is that so?
hi, Thanks for sharing, this is good work. this is helpful. I used codes as yours. I see AirQuality value around 70-80ppm. is this normal? and if I want to calibrate it with real CO2 meter, which codes or variables values do I need to change to calibrate? thanks Scotty..
Hi Scotty , can you add a relay on this project to turn it into CO2 controller? I need the code for build controller for greenhouse
Make more videos plz sir
It's very knowledgeable and good to our environment
Thank you, I try to make as many as i can.
Los valores son muy bajos 0,3 por ejemplo, cuando lo normal es 400ppm.... sabéis cual puede ser la razón? Gracias
Hi Scotty,
Discovering your channel, really cool project !
I was wondering if this sensor was waterproof because I'm not sure you may get the fluctuations of C02 in the air, even close to the tube as it will be stuck in the algae and not into the top of the tube ?
I guess you plan to put at least 2 sensors, 1 at the top of a tube, and 1 outside the box (or not close to the tube) to measure the difference of C02 ?
I also think you might want to add a bit of Olivine at the bottom of your tube to increase the confinement of C02.
My 2 cents !
Kind regards from France :)
Hey Thanks, ill drop another reply to your other comment about the sensor placement, but ill have to look into Olivine I have not seen this before
is it okay if i try to measure the level of co2 produced by a car using the same sensor ?
Hello sir... I'm from Indonesian... I wanna asking u. Can you giving me what the formula for calibration mq 135?
How we can increase its range in radius if we want to detect concentration of CO2 in large area?
i'm getting -27ppm for this code how to correct it
Where is the link describing the plastic modulares that the boards are sitting in?
Hi, They are a modular system I created, check out the video here: th-cam.com/video/t11XWUqPqSs/w-d-xo.html
I was hoping that they were for sale! This is the first good reason I’ve seen to buy a 3D printer.
Do you have a recommendation on a printer?
Lik'd and Sub'd this r8's 8/8
Good explanation. could you please share a code with raspberry pi python code
Thanks, i will be doing videos in future, which will be this code and other on raspberrypi, so keep an eye out for those videos
is it okay to use mq2?
MQ2 sensors work in a similar way including wiring up, but the measure LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide
@@ScottyDIY so all MQ sensors will do?
every MQ sensor is different they have different gases they can detect
MQ-2 Methane, Butane, LPG, smoke
MQ-3 Alcohol, Ethanol, smoke
MQ-4 Methane, CNG Gas
MQ-5 Natural gas, LPG
MQ-6 LPG, butane gas
MQ-7 Carbon Monoxide
MQ-8 Hydrogen Gas
MQ-9 Carbon Monoxide, flammable gasses.
MQ131 Ozone
MQ135 Air Quality (Benzene, Alcohol, smoke)
MQ136 Hydrogen Sulfide gas
MQ137 Ammonia
MQ138 Benzene, Toluene, Alcohol, Acetone, Propane, Formaldehyde gas, Hydrogen
MQ214 Methane, Natural gas
MQ216 Natural gas, Coal gas
MQ303A Alcohol, Ethanol, smoke
MQ306A LPG, butane gas
MQ307A Carbon Monoxide
MQ309A Carbon Monoxide, flammable gasses
I need someone to build a prototype, and think it's you.. Many payment options available. Email if interested.
