Product Description
What is Infrared Obstacle Avoidance IR Sensor Module FC-51 ?
How Infrared Obstacle Avoidance IR Sensor Module FC-51 Works ?
Infrared Obstacle Avoidance Proximity Sensors Module has builtin IR transmitter and IR receiver that sends out IR energy and looks for reflected IR energy to detect presence of any obstacle in front of the sensor module. The module has on board potentiometer that lets user adjust detection range. The sensor has very good and stable response even in ambient light or in complete darkness.
The sensor module can be interfaced with Arduino, Raspberry Pi or any microcontroller having IO voltage level of 3.3V to 5V.
Applications:
- Obstacle avoidance in robots
- Production counting on assembly lines
- Presence detection
- Security systems
Features:
- LM393 Comparator based detection circuit is very stable and accurate
- On board potentiometer sets obstacle detection range
- On board Power LED indicator
- On board Obstacle Detection LED indicator
- 3.0 mm mounting hole for easy mounting the sensor.
- Male header for easy connection
- Good Accuracy: By use of Infra-red LED transmitter the module performs well in Ambient light

Signals and connections of the FC-51 Proximity sensor
- VCC – 3.3 to 5 VDC Supply Input pin
- GND – Ground Input pin
- Signal out – Digital output pin. LOW when obstacle is in range
- Power LED – Illuminates when power is applied
- Signal LED – Illuminates when obstacle is detected
- Variable resistor – Adjust detection distance. CCW decreases distance.
- CW increases distance.
