James and his other colleagues often bike to work to stay healthy. The problem is their work place has only one shower stall. So he built this shower room door sensor to provide an at-desk indication of whether the shower room is free or occupied so that he doesn’t have to run to the bathroom to check its status. While there are other similar projects done before, this has a distinguishing feature that it detects the bolt of the door lock, and therefore it is more reliable than just sensing if the door is shut. He used some paper-clips and post-it notes to build the sensor part and Spark Core to read the sensor output and push the occupancy status to a web page.
