8 Array Line Tracking Sensor Digital

The 8-Array Line Follower Sensor Module (8-Channel Line Tracking Sensor) is commonly used in robotics, especially in line-following robots, where the robot follows a path or track marked with a contrasting line (such as black on white). This sensor module is used to detect and track the line's position relative to the robot, allowing it to adjust its movement accordingly.

Features:

• Sensor Type: Typically uses infrared (IR) sensors to detect the line. The module consists of 8 IR emitters and receivers in a 2x4 array.
• Channels: The module has 8 channels (sensors), providing better detection and accuracy along the path, as each channel corresponds to a sensor.
• Working Principle: When the sensor detects the line (usually black), it reflects less infrared light compared to a white surface, allowing the sensor to detect the difference.
• Output: The output is usually a digital signal (HIGH/LOW) or analog (depending on the version). It can be interfaced directly with microcontrollers to control the motors of a robot.
• Adjustable Sensitivity: Some models allow you to adjust the threshold sensitivity for detecting the line, allowing customization for different surfaces and lighting conditions.
• Voltage Range: Typically operates between 3.3V to 5V DC.
