Ultrasonic Sensor HC-SR04

40.00 EGP

The HC-SR04 ultrasonic distance sensor is one of the most popular sensors used in electronics projects and by hobbyists, thanks to its good accuracy, low cost, and ease of connection and programming with various microcontrollers (such as Arduino, Raspberry Pi, and ESP). The sensor works by emitting high-frequency (inaudible) sound waves and measuring the time it takes for them to bounce off an object and return, allowing for highly accurate distance calculations. Key Specifications: Wide Measurement Range: Covers distances from 2 cm to 4 meters (400 cm), making it suitable for a variety of applications. Excellent Measurement Accuracy: Provides an accuracy of up to 3 mm, ensuring reliable dimensional measurement results. Standard Operating Voltage: Operates on 5V DC and is fully compatible with most common development boards. Easy Connection: Requires only 4 pins (VCC, Trig, Echo, GND) for connection. Narrow Measurement Angle: The effective measurement angle is less than 15 degrees, helping to focus the measurement on specific targets. Reliable operating frequency: Operates at 40kHz to ensure stable performance.
