Davide Gironi has build an indoor ambient quality monitor that is able to measure temperature, humidity, noise and brightness and indicate the ambient quality using 4 bi-color LEDs. He writes:
The data it is logged to the xively.com platform, and displayed to the user through 4 bi-color leds.
It can be used to monitor you Office Ambient Quality over the parameters logged.
This project it is built upon the xively logger ATmega328 library: http://davidegironi.blogspot.it/2014/12/a-web-configurable-xively-logger-build.htmlhttp://davidegironi.blogspot.it/2014/12/a-web-configurable-xively-logger-build.html
