Development of an Intruder Alarm System using Area Scanner and Infrared Sensor

To help with the fight for order and security the developers decided to develop an Intruder Alarm System using Area Scanner and Infrared Sensor. The infrared sensor used is the HC-SR04. It is limited to a detection range of 2 to 400cm. A servo motor rotates the infrared sensor to scan the area for intruders. Upon detection of an intrusion a buzzer will sound to alert people in the premises. Data and information will be displayed on a 16x2 LCD display. Data gathered will be stored in a 24LC16 EEPROM. To manage and integrate all these components together a PIC16F877A microcontroller is utilized.
