HC-SR04/HY-SRF05 Ultrasonic Module

The HC-SR04 / HY-SRF05 Ultrasonic Sensor Module is a versatile and cost-effective distance measuring sensor widely used in robotics, drones, automation, and IoT applications. Utilizing ultrasonic sound waves, it accurately measures distances ranging from 2 cm to 400 cm (4 meters) with a high level of precision.

This sensor operates on the Time-of-Flight (ToF) principle, where it sends out an ultrasonic pulse and measures the time taken for the echo to return, calculating the distance to the object in front of it. The HC-SR04 has a 4-pin interface (VCC, Trig, Echo, GND) and provides fast response times with a high refresh rate, making it suitable for real-time obstacle detection, collision avoidance, and environmental mapping in robotic and drone applications.

The HY-SRF05 is an enhanced version of the HC-SR04 with an additional control pin for flexible operation modes and improved accuracy. Both sensors work efficiently with Arduino, Raspberry Pi, Pixhawk, and other microcontrollers, allowing seamless integration into a variety of projects.
