Fc 51 Ir Sensor Datasheet Hot !new! -

Sensor output stuck LOW (always detects).

2cm to 30cm (Adjustable via onboard potentiometer). Detection Angle: Approximately 35°.

If connecting to an Arduino, ensure it is plugged into the or 3.3V pin, not the VIN pin (which outputs raw input voltage). fc 51 ir sensor datasheet hot

The detection range can be finely tuned via the on-board potentiometer, adjusting the reference threshold on the LM393 comparator:

The is a versatile and cost-effective module for short-range obstacle detection. While it may run warm due to its active IR emission, managing the input voltage and sensitivity can ensure long-term reliability. By following the datasheet specifications, you can efficiently integrate this sensor into your robotics projects. If you'd like to dive deeper, I can provide: A sample Arduino sketch to get you started. A wiring diagram for a multi-sensor setup. Alternatives if you need a longer detection range.

It was a sweltering summer day in the small town of Techville, where the sun beat down relentlessly on the pavement. In a small electronics lab, a team of engineers was busy testing a new prototype for a cutting-edge robotics project. Their focus was on a crucial component: the FC-51 IR sensor.

Input = 9V, Output = 5V, Current draw = 50 mA Power dissipated = (9V – 5V) × 0.05A = 0.2 Watts In a small SOT-23 package, that’s noticeably warm (~40–50°C).

Which (e.g., Arduino Uno, ESP32, Raspberry Pi) is it connected to?
