Hello friends! Today, we will install the PIR Sensor Library for Proteus and build a motion-detection demonstration with Arduino. We will first understand the sensor's output, then install the library, connect the circuit and write a program that reports when a motion event starts and ends. Updates PIR Sensor Library for Proteus Latest version: PIR Sensor Library for Proteus V4.0 (October 2026): HC-SR501 with time delay, the H / L jumper, warm-up, Simple and Advance devices and an Arduino demo Earlier versions: V3.0 (2023) · V2.0 (2020) · V1.0 (2016, this tutorial) Other distance and motion sensors: Ultrasonic HC-SR04 · JSN-SR04T · Sharp IR · TF-Luna LiDAR · VL53L0X · RCWL-0516 · IR Obstacle FC-51 Helping Tools Serial Monitor Advance : a serial terminal window for the UART of your board Se ...
