Aim of the Experiment

The objective of this experiment is to interface an ultrasonic sensor (HC-SR04) with a Raspberry Pi and develop a Python program to measure distances with high accuracy. The experiment demonstrates how to utilize the Raspberry Pi’s General-Purpose Input/Output (GPIO) pins for real-time distance sensing using ultrasonic waves.

Applications

Ultrasonic distance measurement has diverse real-world applications due to its non-contact nature, high accuracy, and reliability. Some key applications include:

1. Robotics and Autonomous Navigation

• Used in obstacle detection and avoidance in robotic vehicles.
• Helps autonomous drones and robotic arms in navigation and object interaction.

2. Automotive and Transportation Systems

• Implemented in parking assist systems to detect obstacles.
• Enhances collision avoidance in modern vehicles.

3. Industrial Automation and Monitoring

• Helps in liquid level monitoring in storage tanks and reservoirs.
• Used for conveyor belt automation, object counting, and packaging processes.

4. Security and Surveillance

• Integrated into security systems for intruder detection.
• Used in motion-sensitive alarm systems for enhanced security.

5. Smart Home and IoT Applications

• Enables automated door opening and smart lighting control.
• Used in proximity-based automation for energy efficiency and convenience.
