Product Description
The HC-SR04+ Ultrasonic Sensor Distance Module is a non-contact distance measuring sensor that uses ultrasonic waves to detect objects. It transmits ultrasonic pulses and listens for the echo to calculate the distance to an object using the time-of-flight principle. Operating comfortably within 3.3–5.5V, it can be directly interfaced with popular microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi.
Ideal for robotics, obstacle detection, level measurement, IoT applications, and autonomous navigation, this module provides reliable distance sensing with good range and accuracy. Its 4-pin interface includes power, ground, trigger, and echo pins, making it easy to integrate into a wide variety of embedded systems.
