They ended up being $100/piece and required a plugin. They used wifi (definitely some room for improvement there) to notify a web interface and an infrared sensor to detect if people were there. It was a really neat project, the cost and implementation requirements just pushed it out of range to deploy it on a library-wide scale right now. > > -----Original Message----- > From: Code for Libraries [mailto:[log in to unmask]] On Behalf Of Andreas Orphanides > Sent: Thursday, August 15, 2013 5:55 AM > To: [log in to unmask] > Subject: Re: [CODE4LIB] Way to record usage of tables/rooms/chairs in Library > > If I were feeling really ambitious -- and fair warning, I'm a big believer that any solution worth engineering is worth over-engineering -- I'd come up with something involving light sensors (a la a gate counter) mounted on the table legs, just above seat height.
