In our project we use a PIR motion sensor to detect movement within a zone it has a 20 foot range to detect motion. An RGB led acts as a status led for the system white if it is off or disarmed, yellow when it is arming, blinking red when it is armed, and green when it finally gets triggered. A buzzer is activated when the alarm is triggered. The system can be armed and disarmed through an html where the user has to enter a password to use the system, there are 3 settings in that html where the system can be disarmed, armed with a loud trigger, and armed with a silent trigger. The silent trigger does not activate the buzzer when its triggered unlike the loud trigger. When the alarm is triggered it will send an email through IFTTT to the owner of the system.
