Application :
1. Obstacle avoidance: The HC-SR04 can be used in robotic applications to detect obstacles and avoid collisions.
2. Distance measurement: The sensor can be used to measure the distance to an object for various applications, such as measuring the height of a surface or determining the distance between two points.
3. Object detection: The HC-SR04 can be used to detect the presence of objects and trigger an action, such as turning on a light or opening a door.
4. Navigation: The sensor can be used in navigation systems to determine the distance to an object and adjust the position or trajectory accordingly.
5. Level detection: The HC-SR04 can be used in level detection applications, such as measuring the level of liquid in a container or determining the height of a surface.
