The space state enables visitors of the hackerspace to know whether the space is open. The state can be checked by various means: an image on the website, spaceAPI, an email alert, or a light outside the space's door.
The space state is set manually using a scissor switch in the space. When engaged the switch closes two circuits (double pole, single throw). One of them is a 12V DC circuit that lights up our logo and doorbell outside. The second pole is connected to a utp pair that runs back to the server cabinet, where an arduino reads out whether the switch is closed. A server polls the arduino every minute and sends out emails, changes the picture on the front page and updates the space api. The source code can be found on github
todo
- Add some relays to the open state, to prevent stand-by power consumtion (arround 40W at the moment).
- Add some more sensors to the arduino to monitor space stats (humidity, temperature, number of times the bel rang, ...)
