CO2 Sensors

Postby raymonvdm » Tue Jan 05, 2016 11:05 am

I would like to add an CO2 sensor to my automation setup to measure the air quality in my house but i haven`t found the best unit yet. I have seen there are more people with this question so i decided to create a topic




Carbon Monoxide

Will kill you if it attaches to the oxygen in your blood. There are security sensors to save life, just like smoke sensors

Visonic MCT-442


Carbon Dioxide

Duco Handleiding
Siegenia Sensoair
Running HS3PRO on PC with Z-Wave / OpenTherm / Plugwise / RFXcom / MQTT / XAP400 / Logitech Media Server and Squeezelite on PI`s

I own this one, http://www.weetwatumeet.nl/product/1433 ... meter.aspx, with some scripting I was able to get the values in HS3. :)

The disadvantage of this one is that it has to be connected trough USB, so now there is an cable visible trough my livingroom to the hallway... Saw someone who was able to read this meter with a rPi, that would be an nice option to make it wireless.

I really can notice better air quality now I'm beter aware of it!

Here is an interesting topic also: http://gathering.tweakers.net/forum/lis ... es/1609383.

Nice!
so you read the C02 directly via usb frm the sensor, did you need to give a command to get the readings?
do you have a link of the RPI solution as well?

Thanks Pieter

No, there is some software needed, ZG View, got it here: http://www.zyaura.com/support/support_software.htm. It generates an CSV file per day with al the readings in it.

Script I use to get the value in HS3:
Code: Select all
Sub Main(ByVal parm as Object)

   Dim Debug=0
   
   if Debug>0 then
      hs.writelog ("CO2", "Co2 logging activated")
   end if
   
   Dim currentDate As DateTime = DateTime.Now
   Dim devIdCO As String = "522"
   Dim devAddrCO As String = "F9"   
      
   if Debug>0 then
      hs.writelog ("CO2", "Current: " & currentDate)   
      hs.writelog ("CO2", "Month: " & currentDate.ToString("MM"))
      hs.writelog ("CO2", "Day: " & currentDate.ToString("dd"))
   end if   
   
   Dim fileName = "C:\Users\freakstar\Desktop\ZyAura_USB_HUB_PC_software\" & currentDate.Year & "\" & currentDate.ToString("MM") & "\" & currentDate.ToString("dd") & ".CSV"
   'Dim fileName = "C:\Users\freakstar\Desktop\ZyAura_USB_HUB_PC_software\2015\12\19.CSV"
   
   if Debug>0 then
      hs.writelog ("CO2", "Filename: " & fileName)   
   end if   

   If My.Computer.FileSystem.FileExists(fileName) Then
      Dim line As String = System.IO.File.ReadLines(fileName).Last()
      
      if Debug>0 then
         hs.writelog ("CO2", "Read: "& line)
      end if      

      Dim fields() As String = line.Split(",".ToCharArray())
      Dim fileTime = fields(0)
      Dim fileCO = fields(1)
      Dim fileTemp = fields(2)
      Dim fileHum = fields(3)
         
      if Debug>0 then
         hs.writelog ("CO2", "Time: "& fileTime)
         hs.writelog ("CO2", "CO: "& fileCO)
         hs.writelog ("CO2", "Temp: "& fileTemp)
         hs.writelog ("CO2", "Humidity: "& fileHum)      
      end if   
      
      'Set values
      hs.SetDeviceString(devIdCO, fileCO & " PPM, " & fileTemp & "C, " & fileHum & "% (" & fileTime & ")", True)
      hs.SetDeviceValue(devAddrCO, fileCO)
      
   Else
      hs.writelog ("CO2", "File not found.")
   End If   
   
End Sub

not sure how the arduino sensors are , but they probably work with the hs3 arduino plugin and are not so expensive

I'm using the Netatmo CO2 sensors. Works perfectly with this plugin.

Someone at Tweakers.net did an interesting project with a Itho CO2 sensor: https://gathering.tweakers.net/forum/li ... 6#45505066
(It seems to have a header that carries a serial signal, which he reads with a ESP8266).

The topic by itself is also interesting btw.

Hi guys
i got in contact with Vladimir :)
check this C02 sensor (update: also with MQTT now)
http://vair.anker-bg.com
http://vair-monitor.com
http://www.ebay.co.uk/itm/281890179126

there is also a version with a small lcd screen

it has got wifi and can upload to a site.
I got in contact with him and he made the upload url flexible so you can upload every x seconds (adjustable)
to for example 192.168.1.10:8080
also you can ask for a nice price and shipping is only around 3 euro.
He made this during a funded Kickstarter, check it out

Im getting 2 pieces soon and will be able to test it

With display and wifi, no he is not a member yet, but mail him and mention me, then he knows which version firmware etc.

Hi,
I am the producer of the "v.Air - CO2 Monitor". (@Pieter, thank you for posting about my device!)
If you would like to order devices - just send me a PM. On the page above you can find some more details and prices of the devices. Also you can have a look on the kickstarter campaign for the motivation of building the device.

If you have any questions (or even better - feature requests) - I will be happy to answer

Regards, Vladimir

Hi Vladimir!

Great project, nice CO2 meters. I might order one soon. One question: how accurate are your sensors (how are they calibrated)?

Thanks!
