The ELECROW Crowtail – Ultrasonic Ranging Sensor 2.0 is a compact and reliable distance measurement module based on the popular HC-SR04 ultrasonic sensor. It emits high-frequency sound waves (40 kHz) and measures the time it takes for the echo to return, calculating the distance to an object. This sensor is ideal for applications like obstacle detection, proximity sensing, and distance measurement in robotics, automation, and IoT projects. It operates with a 5V DC power supply and has a wide effective angle of less than 30 degrees, making it suitable for various environments. The sensor offers a ranging distance from 2 cm to 500 cm with a resolution of 1 cm, providing accurate measurements for a range of applications. Its compact dimensions make it easy to integrate into projects with limited space. Whether you're building a robot, a smart device, or a distance-measuring tool, this sensor offers a cost-effective and efficient solution.
