Transmits infrared light at a specific frequency. Fc 51 Ir Sensor Datasheet

There is a common confusion: the FC-51 can either be or Active HIGH depending on the manufacturer. The original design often outputs LOW when an object is detected and HIGH when no object is present . However, many clones invert this. Always test your module first.

The LM393 compares this voltage drop to the potentiometer setting. If the reflection is strong enough, the comparator flips the OUT pin to 0V. Interfacing FC-51 with Arduino

Serves as the analog-to-digital digitizer, cleaning up the analog curve of the photodiode into a crisp, readable digital square wave for your microcontrollers. 5. Factors Influencing Detection Accuracy I can provide custom code, wiring diagrams, or

When mounted facing downward close to the ground, it distinguishes between highly reflective white surfaces and light-absorbing black lines.

sensor_d = Pin(22, Pin.IN)

The is an affordable, highly efficient electronic module widely used in robotics, automation, and smart home projects. Utilizing infrared (IR) light, this active sensor detects objects within its line of sight, making it a staple for autonomous navigation and proximity sensing. If you share with third parties, their policies apply

Unlike ultrasonic sensors, it cannot provide an exact distance measurement; it only indicates if an object is within the preset threshold. Typical Applications

Digital TTL (Low level when an obstacle is detected, High level when the path is clear)

The following specifications are typical for the standard FC-51 module. Always check your specific vendor datasheet, but the values below are industry-standard.
