The module typically utilizes an for stable detection. Operating Voltage: 3.0V to 6.0V DC (Standard 3.3V or 5V). Current Consumption: ~23mA at 3.3V; ~43mA at 5.0V.
The FC-51 is a widely used infrared (IR) obstacle/line-detection module that integrates an IR emitter and receiver with signal conditioning and often a potentiometer for sensitivity adjustment. It’s popular in hobbyist robotics, line-followers, proximity detection, and simple object-sensing applications. fc 51 ir sensor datasheet hot
