PIR sensor library for proteus - projectiot123 Technology …

14/03/2019· PIR (Passive Infrared) sensor is also known as the motion sensor which measures the Infrared (IR) light radiating from the object in its field of view. So when the object comes in its field of view the reading of the sensor gets disturbed and thus detect the presence the object in front of it. The PIR sensor looks like the one in the following figure: PIR simulation in the Proteus: Now let us consider the …
