Fc 51 Ir Sensor Datasheet Hot -

A: Yes. The FC‑51 operates down to 3.0 V, so 3.3 V is perfectly fine. The output HIGH level will be approximately VCC (3.3 V), which is safe for 3.3 V logic inputs.

The module operates on the physics of infrared reflection. The on-board IR transmitter LED continuously emits infrared light at a fixed frequency.

The FC-51 splits its physical payload between emitting components, optical receiver blocks, logic comparators, and a simple 3-pin system header interface. System Interface Layout Power input line. Connect to the common power rail. GND: System reference ground. Connect directly to the

If your application allows, power the VCC pin through a microcontroller pin, turning the sensor on only when you need to read it. 6. Applications of the FC-51 Sensor Obstacle Avoidance Robots: Essential for autonomous bots. fc 51 ir sensor datasheet hot

: When an obstacle is in front of the sensor, the OUT pin goes LOW, the built-in LED on pin 13 lights up, and you see "Obstacle detected!" in the Serial Monitor.

void setup() Serial.begin(115200); pinMode(IR_SENSOR, INPUT);

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

Ensure connects directly to the 5V or 3.3V pin on your Arduino. Ensure GND connects directly to an Arduino GND pin. Step 3: Isolate the Output Load

If an obstacle is present, the IR light reflects off it.
