Fc 51 Ir Sensor Datasheet Site

The is a low-cost infrared (IR) obstacle avoidance sensor module commonly used in robotics for short-range detection. It functions by emitting an IR signal from a transmitter LED; if an object is within range, the IR light reflects back and is detected by a receiver phototransistor, triggering a digital signal . Core Technical Specifications Specification Operating Voltage 3.0V – 6.0V DC Detection Range 2cm – 30cm (Adjustable via onboard potentiometer) Detection Angle Approximately 35° Current Consumption ~23 mA at 3.3V / ~43 mA at 5.0V Output Type

The module consists of several critical parts integrated into a single PCB:

Technical Specifications Value / Range 3.3V to 5.0V DC Output Signal Digital (Low when obstacle detected, High when clear) Detection Distance 2cm to 30cm (Adjustable via potentiometer) Detection Angle Current Consumption ~20mA at 5V Main Comparator IC Dimensions 32mm × 14mm Pin Configuration and Module Layout

The FC-51 IR sensor is a compact, low-cost infrared sensor module that detects the presence of obstacles or objects within a certain range. It's commonly used in robotics, automation, and electronics projects for tasks such as obstacle detection, line tracking, and object detection. The sensor emits infrared radiation and measures the reflection of this radiation to determine the presence of an object. The is a low-cost infrared (IR) obstacle avoidance

When the object is near the threshold distance, the output can oscillate between HIGH and LOW, as noted in experimental testing. To mitigate this, implement software debouncing (e.g., require multiple consistent readings before triggering) or hysteresis in your code.
