Over to You
Over the course of this chapter, you learned how to interface with sensors that give you informa-
tion about your home (movement, temperature, video and pictures). You acted on this informa-
tion by creating e-mail alerts, and in the last project I introduced an element of remote control.
You now have the building blocks for your next home automation project. Here are some ideas:
❍
Place a door switch on a dog lap and send an e-mail every time your dog enters or
leaves the house.
❍
Detect when your garage door has been open for more than 10 minutes.
❍
Switch of a light when no motion is detected for a period of time.
hese projects, plus many more, are now well within your reach.
