Fc 51 Ir Sensor Datasheet Hot Best -
As John started the robot, everything seemed to work fine. The IR sensor detected obstacles correctly, and the robot moved smoothly around the workshop. However, after a few minutes of operation, John noticed that the FC-51 IR sensor started to heat up excessively. He measured the temperature of the sensor and found it to be around 50°C (122°F), which was much higher than the recommended operating temperature range of 0°C to 40°C (32°F to 104°F) specified in the datasheet.
| Pin | Description | | :--- | :--- | | | Power Supply : Connect to a 3.3V – 5V DC power source. | | GND | Ground : Connect to the common ground of the power supply. | | OUT | Digital Output : Outputs a LOW signal when an obstacle is detected. Connect to a digital input pin on your microcontroller. |
VCC → 5V, GND → GND, OUT → D2
Acts as the brain, comparing the analog voltage from the photodiode against the reference voltage set by the potentiometer.

The FC-51 is a simple but effective tool; however, its simplicity is also the source of its main limitations. As John started the robot, everything seemed to work fine
