TELE-SAFE HOME SECURITY SYSTEM

The Project Team considered many different design alternatives for the
Tele-Safe Home Security System. However, time and money constraints
limited the choices.
• There are different types of sensors which are available that could have
been used to trigger the system such as:
• Infrared sensors
• Heat sensors
• Motion sensors
• Magnetic sensors
• There are different methods that could have been used to connect the
sensors to the system such as:
• Wireless/Bluetooth
• There are different methods that could have been used to power the system
such as:
• One single source powering the whole system instead of multiple
sources.
• The circuitry of the system could have been smaller and more compact.
• The casing for the system and the sensor could have been smaller and
lighter – Perhaps a lighter material?
• To seal the case we could have used something else other than tape.

The four critical components of the project include:
•The Atmel 89C51 Microcontroller.
Used to arm and disarm the operational amplifier.
•The auto-dialer.
When triggered, a phone number is dialed.
•The infrared motion detector.
Creates an infrared beam.
Becomes triggered when the beam is broken.
•The operational amplifier.
Provides the required voltage to the infrared motion
detector when armed.
