HC-SR04 Ultrasonic Distance Sensor Module

The Ultrasonic Sensor uses sound waves to measure the distance between the sensor and an object. It is widely used in applications requiring distance measurement and obstacle detection.

Features:
Accurate Distance Measurement: Uses ultrasonic waves to detect objects from 2 cm to 400 cm.
Simple Interface: Outputs an echo signal that can be easily read by microcontrollers.
Non-Contact Measurement: Detects objects without physical contact, preserving sensor longevity.

Uses:
Obstacle detection in robotics.
Distance measurement in automation projects.
Level sensing in liquid tanks.

Project Examples:
Obstacle Avoidance Robot: Detects and avoids obstacles autonomously using the sensor.
Automatic Parking Assistant: Measures the distance to objects behind a vehicle to aid in parking.
Smart Trash Can: Detects when someone approaches to automatically open the lid.
