Abstract:
PIC is a family of Harvard architecture
microcontrollers made by Microchip Technology. The name PIC
initially referred to “Programmable Interface Controller”. PICs
are popular with both industrial developers and hobbyists alike
due to their low cost, wide availability, large user base, extensive
collection of application notes, availability of low cost or free
development tools, and serial programming. This paper describes
the PIC microcontroller as a main controller, the motion sensor
which is Passive Infra Red (PIR) as a detector, the voltage
regulator module is used to protect PIC and other connected
sensors / actuators from over voltage and lastly, the timer will be
showed by LCD display to count down the timer of the detection
movement. Furthermore, in this paper also explain the basic
concepts of operational on how this system is detected by Passive
Infrared (PIR) sensor through the object.
