IIC and serial communication: compatible with a variety of control schemes; standard IO interface and PH2.0 interface for easy connection. Equipped with a key calibration function: no need to manually adjust the potentiometer, more convenient to use. Onboard MCU reads data from the infrared probe and outputs digital and analog data. Integrated with 8PCS sensitivity infrared sensors to quickly detect the contrast information of black and white lines. Performance and compatibility Eightsensor array delivers fast, reliable line contrast detection with sensitivity; provides both digital and analog outputs for flexible integration. Typical applications Linefollowing robots and automated guided vehicles that require quick and accurate line tracking. Industrial automation tasks such as conveyor or robotic arm alignment and edge detection to improve positioning accuracy. Educational projects and rapid prototyping in embedded systems requiring multisensor line detection and versatile data interfaces.
