• Ultrasonic Range Finder Module
• Wiring connectors (if applicable)

Applications:

• Robotics: Obstacle detection, autonomous navigation
• Industrial automation: Distance monitoring, object detection
• IoT projects: Smart parking systems, security systems
• Home automation: Proximity sensing, gesture recognition

Working Principle:

1. Triggering: Apply a 10us TTL impulse to the TRIG pin to trigger ranging.
2. Transmission: The module sends eight 40kHz square waves automatically.
3. Reception: If an object is detected, the ECHO pin outputs a high-level signal.
4. Distance Calculation: The duration of the high-level signal corresponds to the time taken for the ultrasonic wave to travel to the object and back. Distance is calculated using the formula: Distance = (Duration of high level signal) x (Speed of sound) / 2.

Overall, the Ultrasonic Range Finder Module offers precise and reliable distance measurement capabilities, making it an indispensable tool for various electronic projects and applications.
