Introduction: LiV Pi - DIY Indoor Air Quality Monitor
LiV Pi is a sensor expansion board that turns your Raspberry Pi into a modern indoor air quality monitoring device.
- Use it in your living room
- Use it to test the air quality in your bedroom
- Use in in your greenhouse to measure CO2 levels: higher levels of CO2 make plants grow bigger and faster
- Use it in your garage: gasoline and diesel engines give off large amounts of CO2
- Use it in the conference room at work
LiV measures CO2, temperature, humidity and air pressure.
LiV is open source. All LiV Pi hardware and software files are here.

Dear LiV Raspberry Pi, What parts do I need to build the most advanced version? Could you give me a discount if I buy on Tindie?

How accurate is the finished product? I'd like to set a few of these up just for the sake of curiosity.

Hello,
Sensor accuracy info for LiV RPi is available here. If you do a search on amazon.com for "indoor air quality monitor CO2" you will see quite a few similar devices that sell in the USD 125-300 range. Most of them use the same auto-calibrating CO2 sensor that LiV uses. Please go to step 7 on this page if you want to find out more about the K30 sensor. Please send me an email at the info address listed on www.livrpi.com if you would like to find out more about LiV's accuracy or the device in general. If you are interested in testing LiV RPi, I might be able to offer you a discount if you order your unit on tindie.
Best Regards,
-Alfred

For some reason the first two links point to the last link I added (tindie store). Either I don't know how to use the comment editor or this is a software bug. Anyways, here are the three links again:
