Line Follower Sensor The line follower sensor is a device that detects and follows a specific path or line on the ground. It's commonly used in robotics and automation to create autonomous navigation systems. This sensor uses a combination of light and darkness to detect the line, emitting infrared beams onto the surface below. If the beam hits a dark area (the line), it returns to the sensor as a signal, indicating the path ahead is clear. This process repeats rapidly, allowing the sensor to continuously track the line and make adjustments in real-time. Line follower sensors come in various types, including analog and digital models. Analog sensors produce a continuous output voltage that changes depending on the distance from the line, while digital sensors provide a binary signal indicating whether the line is present or not. These sensors have numerous applications, such as guiding robots through mazes, creating autonomous vehicles, and even assisting visually impaired individuals navigate through space. The versatility and accuracy of line follower sensors make them an essential component in various fields, from robotics to assistive technology.
