The module features a 3-pin header for easy connection to microcontrollers like Arduino or Raspberry Pi. Power input (3V – 5V). GND: Ground. OUT: Digital output interface. Key Features & Components

If it , test the functionality by passing your hand in front of the sensor. The onboard "Obstacle" LED should light up. Best Practices for Safe Operation fc 51 ir sensor datasheet hot

The module runs warm because of the linear regulator and continuous IR LED drive. As long as you can touch it for a few seconds without burning, it’s likely fine. If it smells or exceeds ~75°C, cut power and inspect your wiring. The module features a 3-pin header for easy

❌ Digital output only – cannot measure exact distance ❌ Susceptible to ambient IR (sunlight, incandescent light) ❌ Detection distance varies with target reflectivity ❌ May require physical LED alignment for maximum range OUT: Digital output interface
