I am working on an a Raspberry Pi based, internet connected indoor air quality monitor called LiV Pi. LiV is an open source hardware and software project. LiV measures temperature, humidity, air pressure and CO2 levels. I connected LiV to my home network. I wanted to be able to have a Intranet website on LiV where I can to see real time measurements and graphs. I used Python Flask to do that. I also exposed REST JSON APIs in Flask. The APIs can be used by developers who would like to integrate LiV data with their applications.
