I’m gonna share one of the project I had in my course subject, Microprocessor here. The title of my project is GPS sensor. So I was required to interface with GPS sensor by using Intel 8085 microprocessor. The language used is assembly language.
From Wikipedia, Passive Infra-Red sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects n its field of view. The term passive refers that PIR sensor does not emit or generate any energy for detection purpose.
