Description
HC-SR04 Ultrasonic Distance Sensor Module – Accurate Range Finder for Arduino and IoT Applications
The HC-SR04 is a widely used ultrasonic distance sensor that uses ultrasonic sound waves to measure distances between 2cm to 400cm with high accuracy. It operates by emitting a sound pulse and measuring the time it takes for the echo to return, making it perfect for non-contact distance measurement.
Compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers, this sensor is ideal for robotics, obstacle avoidance systems, smart parking, water level detection, and IoT automation projects across Bangladesh.
Key Features:
Measuring Range: 2cm – 400cm
Accuracy: ±3mm
Operating Voltage: 5V DC
Interface: 4-pin (VCC, Trig, Echo, GND)
Low power consumption
Simple digital pulse interface
Compact and lightweight design
Applications:
Obstacle detection and avoidance in robots
Smart parking and vehicle distance monitoring
Water tank level sensing
Security and motion sensing systems
Educational and IoT-based projects in Bangladesh
The HC-SR04 ultrasonic sensor is a cost-effective and easy-to-use distance sensor for various embedded, automation, and real-time measurement projects.
