GNUPott continuously observes the lighting situation in a certain room or place using a small photo diode. We actually use it to check whether light is on or off in both men“s and ladies“ room with one photo diode per room, but the technology itself can of course be used for a wide range of different purposes. The diode status information can be requested of the electronic circuit using USB technology.
In our case, a server connected with this USB device automatically checks the status every 15 seconds and provides an image depending on the result per HTTP. Consequently, anyone can easily watch the toilet status image over a specific URL, whenever this might be necessary. The image we used to display that can be seen below.
