Re: Senseair S8

I just installed RPIEASY,

the Senseair option in the device tabs seems to be missing. Is there a way I could add it?

Re: Senseair S8

I’m using the 5V pin from the Raspberry Pi.

Should I use the 3.3v?
The data sheet says it can only handle between 4.5v and 5.25

I’m pretty sure the raspberry pi settings are fine, because when I connect the Raspberry Pi’s RX and TX directly, the Pi is able to pickup what’s being sent out

Senseair S8

Anyone one else have problems with getting the S8 co2 sensor working?

No matter what I do, it seems to repeat back x00

Anyone have idea what’s going on?

It be checked the connections, I looped the TX and RX into each other on my Raspi’s side, and the software is able to read it.

I wrote to Sensair directly.

They sent me this

That's the interval for the MH-Z19 sensors.
The S8 abc period is 15 days. So I guess my real question is:
If I interrupt the power within the time, will it prevent it from doing abc?

Re: Turning an S8 ABC off

Will powering down the sensor once a day prevent it from auto calibrating?

Re: Turning an S8 ABC off

My sensor will be sitting in an environment that is constantly over 5000 ppm. So I feel the abc won’t be a good thing to have on.

I only have a Mac, is there a Linux or max port for that?

Turning an S8 ABC off

Hey everyone, I just bought my S8, and am eagerly awaiting it’s arrival. I have found that there are not a lot of good python Libraries for it. I want to turn off it’s ABC because it’s going in a very high co2 environment. I found one library that has a command just called ‘s8_abc’. It doesn’t say i...

Co2 Sensor

Hey,

Does anyone know if either a co2 sensor that can read up to 30000ppm.

Or a sensor that can read how much dissolved co2 there is in water?

Re: The MH-Z19 in high co2 and humidity

I opened the window today, and the numbers are closer to what it was when I used it out of the box. So I guess the theory behind ABC is pretty good. I am getting less reading of EXACTLY 400ppm, so I am assuming your statement about it clipping was also right. I am going to leave it for another day a...

Re: The MH-Z19 in high co2 and humidity

I understand what you’re saying. I’m going to leave it the way it is for today, so I can see how it jumps up at night. Tomorrow morning I’m going to open the windows and see how much that changes. One thing was different today actually. I wasn’t home. This is the first day I had to work since I set ...

Re: The MH-Z19 in high co2 and humidity

I haven’t changed a thing. The windows are still closed. The environment is the same.

I was at work when I posed the question, when I got home it was at 400 ppm

Ok, so I just got home and the levels are actually realistic! Atm it’s at 400ppm, and has been since 2pm I’m not really sure what happened. When I look at the log, it has been going down little by little since at least yesterday. The only thing I changed was yesterday. I figured the ABC might be tur...

Re: The MH-Z19 in high co2 and humidity

There is a tonne of plants in the room.

I thought it might be that, but I also thought that if the plants where making a big difference, the day time levels would be lower.

Re: The MH-Z19 in high co2 and humidity

Ok. I’ll put a opaque cup over it, but leave some space on the bottom for ventilation, to make sure it’s not a light problem. And open a some windows.

However, it’s really high at night when the lights are off, so I don’t think it’s from the sun.

I’ll take a look

Re: The MH-Z19 in high co2 and humidity

So I have been running this sensor for about a day and a bit.

Just out on my counter. My co2 levels are showing between 1200-1600ppm. Is this normal?

Is it because it has a burn in time, or because it hasn’t set the abc properly yet?

That seems really high

Re: The MH-Z19 in high co2 and humidity

I am reading the instructions for this sensor here . Their ABL calibration takes 24hours. So before I put it in my container, I’m going to let it run for 48 hours in my kitchen (I don’t use gas). Then turn off the abc before I put it in the container. I will repeat the process when the results start...

Re: The MH-Z19 in high co2 and humidity

You need to understand the CO2 sensor will "degrade" over time. Like I said before, the amount of IR absorption is measured, but for that you need to know how much IR was put in. The light source can (and will) degrade over time. Also the detector may become dirty and thus measure less IR...

Re: The MH-Z19 in high co2 and humidity

Also make sure to have the sensor outside the high CO2 environment every now and then to allow to re-calibrate it to 400 ppm as sensors may become saturated at some time (months). When left in a closed container for a while, you must make sure to turn off the ABC function of the sensor. This is wha...

Re: The MH-Z19 in high co2 and humidity

I’ll give it a try.

I’ll take precautions to make sure it doesn’t get wet.

How long is a while?

If I leave it running overnight in my living room, is the sufficient enough to keep it at 400ppm?

I could then in theory, make the container out of black acrylic, and just make a small hole for the ir to shine into. As I can silicone around it to make it air tight. Or, use some kind of rubber gasket. Would that work? I remember reading the hm-z19 compensates for temperature. Does the ir gather t...

Re: The MH-Z19 in high co2 and humidity

I saw something simular to that used for beer manufacturing. I’m not opposed to the idea, but I’m more worried about how to calculate the results. If the cup’s rim is submerged around the water, the co2 inside the cup becomes proportional to the co2 in the water. If I’m simply collecting the air tha...

Re: The MH-Z19 in high co2 and humidity

My understanding is that the cup might get up to 20,000ppm,

But that’s by my calculations, which might be faulty. I’m very new to this stuff, I’m trying to figure this out. I have a ccs118, but the highest it ever got was 1995ppm

Is there a sensor you guys could recommend?
