It’s hard to tell when a room on another floor, or across the building is occupied or vacant. At Adafruit we have a popular meeting room however sometimes it’s being used and if you want to have a meeting, you have to wait or go somewhere else. How handy would it be if we had a public dashboard to view if the room is occupied? Using an Adafruit FunHouse board, a infrared PIR sensor, and AdafruitIO WipperSnapper, we can make it happen.

Additionally, in the bonus section, you can install a status light to add a layer of visibility to the room’s occupancy status.

Prerequisite Guide:

WipperSnapper is an interface for Adafruit IO, Adafruit's incredibly easy-to-use IoT platform, designed to turn any WiFi-capable board into an IoT device without programming a single line of code.
