The sensor is highly dependent on the object's color and texture. Dark or matte black surfaces reflect less IR light and may be harder to detect than white or reflective ones.
The is one of the most popular, affordable, and essential components in the hobbyist and professional robotics community. Whether you are building an automated line-following robot, a smart parking system, or a basic collision detection mechanism, the FC-51 offers a reliable solution. fc 51 ir sensor datasheet hot
The most frequent cause of a burning hot sensor is swapping the and GND wires. The module lacks reverse polarity protection. Reversing power forces massive current through the LM393 chip, causing instant overheating. 2. Overvoltage The sensor is highly dependent on the object's
