Hello friends! Today I will show you how to install our Ultrasonic Sensor Library for Proteus and use it with an Arduino Uno. We will begin with the library files, place the sensor on a schematic, connect its simulation input and then read the distance through the Virtual Terminal. This is the original HC-SR04-style library introduced in this tutorial. Updates Ultrasonic Sensor Library for Proteus Latest version: Ultrasonic Sensor Library for Proteus V2.0 (October 2026): HC-SR04 with real TRIG and ECHO timing, Simple and Advance devices, test tools and an Arduino demo Earlier versions: V1.0 (2015, this tutorial) Other distance and motion sensors: JSN-SR04T · Sharp IR · TF-Luna LiDAR · VL53L0X · PIR HC-SR501 · RCWL-0516 · IR Obstacle FC-51 Helping Tools Serial Monitor Advance : a serial ter ...
