It can detect the presence of a person by identifying their motion inside. It is used in banks for security purposes. PIR (Passive Infrared Sensor) also known as a motion sensor, is used to detect motion using infrared rays. If you don’t know what is PIR sensor, you must read this post first where I’ve briefly discussed the Interfacing of PIR sensor with Arduino. Moreover, you should also check the latest version of PIR Sensor Library V3.0. We have already shared the digital PIR Sensor Library for Proteus V1.0. In this tutorial today, I’m going to share the Analog PIR Sensor Library for Proteus.
