is a meter for $229 that measures CO2, Temperature, and Relative Humidity. Here's the thing. You can hack it to control a cheep CO2 regulator. Like one for $80 on Amazon. By adding a $2 Omron G5V-1 relay you can swith 125VAC for 0.5 A. That's a 62.5W device. BTW that CO2 Regulator draws...

Used for remote view of CO2 meter AQ100.

the aq500 sw is right on the downloads page. but you can use the latest DAS sw too. it downloads logs. in the advanced section you can program your thresholds and outputs. pwd:peacefuldove thx 2 Andrew ;) the log download didnt complete for me. so not sure how far back it goes. but if i...

On more thing. The CO2 Meter guys updated the DAS software. It updated the drivers and made the graphing work. you can also use the AQ500 sdk and SW on the AQ100

Hey. So. Good news. I was out for a couple of weeks on work travel so I haven't gotten back to update this. I spoke to Andrew over at CO2 meter. Cool dude. He designed the thing and told me a little about it. I have to say, if you know what your doing, the AQ100 is a steal at $199...

I'll look for their number and try tomorrow. It seems like they have a lot of sw bugs. i tried to open the vb project in visual studio express but am getting some, vb error on a usb function call. and its not the charts just flatline, its the whole program crashes, and says the program...

Hey! Cant keep me down! Glad to see you on here. Im still having issues with the DAS logging SW that does the charts. It just "stops working" after a few seconds. are you running it on vista? xp? or win7? if i remember right. been many bowls ago... DAS worked... then i downloaded...

so i put a multimeter across the coil pins on the board were the relays are supposed to go. i read 5vdc on the relay coil pins below 1200ppm and 0vdc above 1200 ppm. so, it works! off to buy my $2 relays...:)

ok. I was able to change the thresholds for CO2 to trigger relay2. one on the end... i set it to 0-1200, exclusive, relay 2, on sensor 0. this image doesnt show the right fields but you get the point... the program sets when the relay fires. which is basically a 1amp switch.

Yeah. That's where I got the PN from. You can find them by google searching under shopping. It looks like they are powered by the transistors just above them. This circuit is intact in the AQ100 even though it's a picture of the AQ500. The problem I'm having is programing the threshold...

Hey. I joined this site cause I saw your post on the AQ100. I bought one of these and looked under the hood. I see two locations for what seems like G5V-1 relays. Was planning on using this with a UPB I/O device to control a UPB appliance outlet for the CO2 solenoid. Wanted to know your...
