I was staying at a hotel in Houston and noticed that there was an infrared motion detector (one that looks exactly like the kind installed with most standard security systems) on the wall. It took my a little bit of pondering to figure out the purpose. Do you know what it does?
It turns the air conditioner on and off. That probably saves the hotel a bunch of money in electricity costs, which is great for them. My question: Why they couldn’t they make the sensor blend in so that I didn’t have to see it?
