It’s a bit uncomfortable for all celebrations included if somebody is waiting right outside the bathroom door. This system assists to reduce that problem by letting the next individual understand when the loo is available. [Akiba] has been working with the people at Loftworks, a style business in Tokyo, to get the condition beacons seen above up as well as running.
The personnel is mainly women as well as there is just one single stall women’s toilet on each of the three floors. The boxes above represent the three stalls, utilizing colored light to suggest if a bathroom is offered or in use. Detection is based on a PIR movement sensor in each stall. They interact back with the screen units wirelessly, which at first provided rather a problem. The doors on the bathroom are steel, as well as when closed they effectively block communications. The 900 MHz radios utilized in the system are on the 802.15.4 protocol. however they can be set a couple of different methods by moving resistors. Each came configured for the fasted data throughput, however that’s not truly necessary. By altering to a slower configuration [Akiba] was able to repair the communications problems.
We keep in mind seeing a similar bathroom sign in a links publish a long time ago.
