Fc 51 Ir Sensor Datasheet Hot
Digital output pin. Can hook up to any standard microcontroller I/O pin or trigger a relay module directly. Integrated Indicators & Hardware
| Parameter | Value | |-----------|-------| | Supply voltage | 3.3V – 12V (5V recommended) | | Current consumption | 20–50 mA (depends on LED and regulator) | | Sensing distance | 2cm – 30cm (depends on object reflectivity) | | Output type | Digital (TTL, active low) | | Comparator IC | LM393 | | Operating temp range | –25°C to +85°C |
: A short circuit inside the IR receiver component itself can cause it to burn. FC-51 Technical Specifications fc 51 ir sensor datasheet hot
@ 5.0V leetechbd.com/product/infrared-obstacle-avoidance-module-fc-51/ Digital (Low on obstacle, High on no obstacle) Comparator IC Dimensions 3. FC-51 Pinout and Connections
Place a 0.1µF ceramic capacitor across the VCC and GND lines close to the sensor to filter out voltage spikes. Digital output pin
FC-51 IR Obstacle Avoidance Sensor is a digital infrared proximity module used primarily in robotics for object detection. It uses an LM393 voltage comparator
user wants a long, informative article on the FC-51 IR sensor, specifically targeting the keyword phrase "fc 51 ir sensor datasheet hot." The user likely wants a comprehensive guide that is well-optimized for search engines. This guide should be a primary resource that explains the sensor's specifications, pinout, working principle, interfacing with microcontrollers like Arduino, practical applications, and troubleshooting. FC-51 Technical Specifications @ 5
void loop() if (digitalRead(irSensor) == LOW) Serial.println("⚠️ Obstacle detected!"); else Serial.println("Clear path");
Place the FC-51 inside a dark drawer or wardrobe. The moment you open it, the sensor detects the change in reflection (or your hand reaching in) and turns on an LED strip. No more fumbling for clothes in the dark.
Mount an FC-51 below a soap or sanitizer bottle. When hands pass within 10 cm, the sensor triggers a small pump or servo. Result: A no-touch dispenser that reduces germ spread—perfect for kitchens or entryways.
