Smoke and Heat Detectors: Detect smoke and heat. 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.
