medic alert services ADT smoke sensors sound off if a fire is detected. ADT representatives are alerted and the fire department will be called. ADT provides a product option called ADT Pulse so that customers can arm and disarm their home security siren system remotely. The Pulse product uses a wireless modular device called a Z wave. The Z wave device connects to a remote device such as a laptop or mobile phone. For example, if an owner forgets to arm the security system before leaving home, she can turn it on from her computer at work or from her mobile phone.

Chapter II:Our Home Alarm SystemOur Home Alarm System:Our project’s main concern was to build a Home Alarm System using a PIC microcontroller. We started off our project by coding the Keypad, then LCD and the final touch was the sensor. We also added two types of buzzers: one to sound the alarm and the other as a key tone buzzer. The final result turned out to be the following:Figure3. Our Home Alarm SystemMaterials Used: Cost:PIC16F877A 7$4X4 Keypad 2$JHD 162A LCD 6$6V Alarm Buzzer 0. 5$Key tone Buzzer 0.
