2cm to 30cm (Adjustable via onboard potentiometer)
When an electronic component gets hot, it means it is dissipating excess power as heat ( ). Here are the primary reasons this happens to the FC-51: 1. Overvoltage (Exceeding 5V DC)

The FC-51 IR sensor is a popular, low-cost infrared proximity module widely used for obstacle avoidance in robotics and automated systems. It operates by emitting infrared light and measuring the reflection from nearby objects. Technical Specifications fc 51 ir sensor datasheet hot
The FC-51's operation is elegantly simple, based on the principle of infrared reflection:

The datasheet for the FC-51 IR sensor provides essential information on its electrical and physical characteristics. Here's a breakdown of the key specifications:
: A short circuit inside the IR receiver component itself can cause it to burn. FC-51 Technical Specifications
The most frequent cause of a burning hot FC-51 is accidentally swapping the power pins. The module has three pins: VCC, GND, and OUT.
