4-CH IR Line sensor Module Battery Holders which can be set to4 CH IR Line Sensor Module A 4 channel IR line sensor module is a type of sensor that uses infrared (IR) technology to detect the presence or absence of a line or object. It typically consists of four individual IR sensors, each with its own phototransistor, that are arranged in a row. The module can be used to detect the position of a line, the edge of an object, or the presence of an obstacle in a robotic or automation application. It is often used
