Fc 51 Ir Sensor Datasheet Hot Fixed Direct

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

Always calibrate using the actual objects your system will encounter. If you need consistent range regardless of surface, consider a time‑of‑flight (ToF) sensor or a sharp IR distance sensor.

If you are currently troubleshooting a circuit, let me know or which specific component on the board feels the hottest so we can pinpoint the exact fix. Share public link

: If the module is hot to the touch, check for a reverse polarity connection (VCC/GND swapped) or a short circuit in your wiring. fc 51 ir sensor datasheet hot

If your FC-51 is uncomfortably hot:

: Typically 2cm to 30cm (adjustable via the onboard potentiometer). Detection Angle : 35°.

| Condition | Cold Start (25°C) | Hot Running (50°C) | | :--- | :--- | :--- | | Detection distance (max) | 30 cm | 18 cm | | False positive rate (no obstacle) | 0% | 30-40% after 20 min | | Output switching frequency | 1 kHz | 400 Hz (sluggish) | | Current draw | 22 mA | 34 mA | The FC-51 IR sensor is a popular, low-cost

Used on assembly lines to count objects passing by.

This article serves as a complete, crowdsourced datasheet supplement. We will dissect the official specifications, explain why the sensor runs hot, and provide actionable fixes to stabilize it.

The FC-51 module is straightforward to wire, featuring a simple 3-pin male header for easy connection to microcontrollers like Arduino or Raspberry Pi. If you need consistent range regardless of surface,
