It uses ultrasonic waves to detect objects and returns precise distance readings with a typical accuracy of ±3mm.

The module operates using a simple Trigger and Echo interface, making it easy to integrate with Arduino, ESP32, Raspberry Pi, STM32, and other microcontrollers. It’s commonly used in applications such as smart parking systems, obstacle avoidance robots, liquid level detection, and automated measurement tools.

The sensor transmits an ultrasonic burst at 40kHz, waits for the echo, and calculates the distance based on the time of flight. It is lightweight, stable, and designed for both beginners and advanced developers.

Key Features:

  • Operating Voltage: 5V DC

  • Operating Current: 15mA

  • Measurement Range: 2cm – 400cm

  • Accuracy: ±3mm

  • Frequency: 40kHz

  • Output: Digital pulse width (Echo)

  • Interface: 4-pin (VCC, Trig, Echo, GND)

  • Measuring Angle: 15°

  • PCB Size: 45mm × 20mm × 15mm

Applications:

  • Robotics and obstacle detection

  • Smart parking systems

  • Distance measurement tools

  • Water tank level monitoring

  • IoT automation and security systems

  • Autonomous vehicles and drones
