Small footprint with a 3mm screw hole for easy mounting on robot chassis. Technical Specifications Specification Operating Voltage 3.3V to 5V DC Detection Distance 2cm to 30cm (Adjustable via potentiometer) Detection Angle Output Type Digital Logic (Low = Object detected, High = No object) IC Controller LM393 Voltage Comparator Current Consumption Pin Configuration The module typically features a 3-pin header: VCC: Connects to power (3.3V - 5V). GND: Connects to the common ground. OUT: Digital output pin connected to the microcontroller. Typical Applications
The FC-51 is great for obstacle avoidance. It works by emitting IR light; when an object reflects that light back to the receiver, the sensor triggers a digital output.
The is a fantastic choice for anyone starting with electronics or working on projects where simple, reliable, and cost-effective object detection is needed. Its straightforward datasheet, combined with the practical advice above, equips you with everything necessary to start building responsive and intelligent systems. fc 51 ir sensor datasheet hot
