Air Quality Sensor
-
I was looking for some other gas sensor, but these have no shield ready to connect to arduino :
Sensor Operating Voltage Heater Power MiCS-2710 (NO2) 2.5 V 43 mW MiCS-5525 (CO) 5.0 V 76 mWdo I need a dedicated 2.5 V linear regulator such as Microchip TC1071VCT713 ?

@hek about initial calibration, how would I do check if there is a value in the eeprom or not, and if not run an initial calibration ?

Hi,
First of al I'm a novice in all of this. I can read some code but the whole arduino thing is new to me.I tried to get the MQ135 working on my uno with tearing apart the : https://github.com/empierre/arduino/blob/master/1.3/MQ135dgi.ino.
I tried to pull out the bits and parts to get a accurate reading on my serial monitor.It sometimes read 1 or 2, but most of the time it is 0.
Can it have something to do with it being mounted on its own PCB? (I ordered the one suggested in the store..)
Can someone help me out?Groetjes Mark

@Omemanti hello have you plugged it on the right pins, this is an analogic sensor to be plugged on A0, with 5V and GND pins. Don't wire the digital one, useless...
My minimal value is 53.. so not 0 or 1 hwich looks more like the digital output ;-)

Hi,
Where can I find AirQuality1.xml?? (or all files related to this device if there are others then the .xml)01 09/03/14 13:46:53.685 ctrl_chr[31;1mDevice_LuaUPnP::LoadDeviceDoc can't load /etc/cmh-lu//D_AirQuality1.xmlctrl_chr[0m <0x2acc9000>
02 09/03/14 13:46:53.686 ctrl_chr[33;1mJobHandler_LuaUPnP::m_sMissingFile_set /etc/cmh-lu//D_AirQuality1.xmlctrl_chr[0m <0x2acc9000>Seems like if this file is missing it brakes the whole MySensors plugin.
All devices related to MySensors plugin are blank and nothing seems to update.
Deleting the device that use AirQuality.xml will make the rest work again.Help!!

@hek
ahh, that's why I cant find it... no pressure from my side to get one done but maybe we should mention this little detail on the MySensors building page just as a heads up for others since there is a sketch published and all... -
I made a template but I'm unable to test it...

- Carbon Dioxide – CO2
- Oxygen – O2
- Methane – CH4
- Hydrogen – H2
- Ammonia – NH3
- Isobutane – C4H10
- Ethanol – CH3CH2OH (aka C2H5OH or C2H60)
- Toluene – C6H5CH3
- Hydrogen Sulfide – H2S
- Nitrogen Dioxide – NO2
- Ozone – O3
- Hydrocarbons – VOC
- Chlorine CL2
- Ammonium NH4
- Ethanol CO2H50H
- Methyl CH3
- Acetone CH3_2CO
- LPG (both C3H8 C4H10)
@hek here is an updated list from the Wunder Weather list of reportable gases:

@Yveaux I know you are strong at finding datasheet... can you find one for me ? I can't find the 2SH12 sensor altgough I've asked for it to all suppliers on aliexpress...
Same for theWSP1110

@epierre Couldn't find it either, sorry...
I wouldn't buy a $52,- component without a datasheet, if I were you... -
@Yveaux When I asked for the WSP110 they sent me only this (not the same for this one is HCHO and well documented...) :
