Function: Ultrasonic distance measuring sensor module designed for accurate, non-contact distance detection using high-frequency sound waves.

Operating Principle: Emits ultrasonic pulses and measures the time delay of the echo to calculate the distance between the sensor and an object.

Range & Accuracy: Detects objects from 2 cm to 400 cm (4 meters) with high accuracy of ±3 mm under normal conditions.

Operating Voltage: Works at 5V DC with typical operating current around 15 mA, compatible with most microcontrollers and development boards.

Construction: Equipped with dual transducers — one transmitter and one receiver — mounted on a sturdy PCB for consistent performance.

Interface: Provides simple 4-pin connections (VCC, Trig, Echo, GND) for easy integration with Arduino, Raspberry Pi, ESP32, and other control systems.

Applications: Commonly used in obstacle avoidance robots, distance measurement systems, parking sensors, automation, and IoT projects.

Design: Compact and lightweight module offering fast response time and stable output; ideal for embedded and robotics applications.
