Bringing It All Together
With our PassiveInfraredSensor and SmtpService classes, it’s a piece of cake to build
a burglar alarm with email notifications. Connect the PIR sensor to the Eth-
ernet shield, as shown in the following figure.
Then enter the following code in your Arduino IDE:
Ethernet/BurglarAlarm/burglar_alarm.h
#ifndef __BURGLAR_ALARM_H__
Line 1
#define __BURGLAR_ALARM_H__
-
#include "pir_sensor.h"
-
#include "smtp_service.h"
-

class BurglarAlarm {
-
PassiveInfraredSensor _pir_sensor;
-
SmtpService _smtp_service;
-
void send_alarm() {
-
Email email(
10
"arduino@example.com",
-
"info@example.net",
-
"Intruder Alert!",
-
"Someone's moving in your living room!"
-
);
15
_smtp_service.send_email(email);
-
}

BurglarAlarm(

const PassiveInfraredSensor& pir_sensor,

const SmtpService& smtp_service) :

_pir_sensor(pir_sensor),
