LiV Pi - Indoor Air Quality Monitor
LiV Pi board is a sensor expansion board that turns your Raspberry Pi into a modern indoor air quality monitoring device that measures CO2, temperature, humidity and air pressure. 

• Use it in your living room
• Use it 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
• ​Integrate LiV with your air quality monitoring solution  

​Why CO2?
Carbon dioxide is a good indicator of indoor air quality. Carbon dioxide is a natural component of air. By volume, dry air contains nitrogen, oxygen, argon, a small amount of carbon dioxide and even smaller quantities of other gases. The amount of CO2 in a given air sample is commonly expressed as parts per million (ppm). The outdoor air in most locations contains about 390 parts per million carbon dioxide.
Inside a building, people and plants are the main sources of CO2. Whenever we exhale, our lungs release CO2. Plants also release CO2 at night due to cellular respiration. Higher levels of indoor CO2 indicate that not enough fresh air get into the building and consequently it is possible that other pollutant and allergenic agents such as Volatile Organic Compounds are also present in the air.
