The HC-SR04 Plus Ultrasonic Sonar Sensor (2021 edition) is an enhanced version of the classic HC-SR04, designed for greater flexibility and compatibility with modern microcontrollers. Unlike its predecessors, this version supports an input voltage range of 2.8V to 5.5V, making it ideal for both 3.3V boards like ESP32/STM32 and 5V boards like Arduino UNO/Nano. It introduces four communication modes (GPIO, I2C, 1-Wire, UART), offering users versatility to integrate the sensor according to their project requirements. With a reliable distance range of 2cm to 400cm, this sensor is widely used in robotics, automation, security, and IoT applications. Its jumper-based configuration makes switching between modes simple, making it a must-have sensor for advanced projects. Featured By RoboticsBD.
