Arduino uno User Manual

CHAPTER 11
Creating a Burglar Alarm with Email
Notification
In the preceding chapter, you learned how to access networking services with
the Arduino in various ways. Adding networking capabilities to an Arduino
enables you to create countless useful projects. In this chapter, you’ll use
your newly gained knowledge to build a real-world project: a burglar alarm
that uses email notification.
The burglar alarm will send you an email whenever it detects movement in
your living room during your absence. To achieve this, you first have to learn
how to send emails. You already know a lot about networking with an Arduino,
so this won’t be too difficult.
You also need to know how to detect motion. So you’ll also learn how passive
infrared (PIR) sensors work and how you can control them with an Arduino.
At the end of the chapter, not only will you have learned some useful skills,
but you’ll also feel much safer when the burglar alarm is running.
