HC-SR04 Ultrasonic Distance Sensor – Accurate & Reliable Distance Measurement

$63.07 $85.14
The HC-SR04 Ultrasonic Distance Sensor Module is a high-performance, cost-effective solution for accurate non-contact distance measurement. By transmitting 40kHz ultrasonic sound waves and measuring the echo return time, this sensor delivers fast, stable, and precise distance readings from 2cm to 450cm. Designed for microcontroller platforms such as Arduino, ESP32, Raspberry Pi, STM32, and other 5V systems, the HC-SR04 is ideal for robotics, automation, smart devices, security systems, and educational projects. Its low power consumption, compact design, and simple 4-pin interface make it perfect for beginners and professionals alike �� ⚙️ Technical Specifications Operating Voltage: 5V DC Operating Current: < 2mA Ultrasonic Frequency: 40kHz Trigger Input: 10µs TTL Pulse Echo Output: TTL Pulse Width Signal Logic Level: 5V High / 0V Low Detection Angle: ≤ 15° Measurement Method: Time-of-flight ultrasonic ranging �� Pin Configuration �� VCC – 5V Power Supply �� TRIG – Trigger Signal Input �� ECHO – Distance Pulse Output �� GND – Ground
