5V HCSR04 Ultrasonic Sensor 4pin - IoT

This item is Factory Sealed under category - IoT The 5V HC-SR04 Ultrasonic Sensor Module is a precise distance-measuring device designed for a wide range of applications, including robotics, automation, and object detection. Operating on a simple 4-pin interface (VCC, GND, Trig, Echo), this sensor emits ultrasonic pulses to measure distances from 2 cm to 400 cm with an accuracy of ±3 mm. The module requires a 5V power supply and is compatible with popular microcontroller platforms like Arduino, Raspberry Pi, and ESP32. It uses a time-of-flight method to calculate distance, providing reliable and consistent results in real-time. The sensor’s compact design and ease of integration make it ideal for obstacle avoidance, proximity sensing, and environmental mapping projects. With robust performance and low power consumption, the HC-SR04 is a cost-effective solution for applications requiring accurate non-contact distance measurement.
