It consists of an IR transmitter and receiver pair, using a comparator circuit (LM393) to provide a simple digital output Ktechnics Systems Technical Specifications Operating Voltage: 3.0V to 6.0V DC Current Consumption: approximately at 3.3V and Detection Range: 2 cm to 30 cm (adjustable via onboard potentiometer) Art of Circuits Detection Angle: Output Signal: Digital (High = No Obstacle, Low = Obstacle Detected) Art of Circuits Dimensions: Approximately 43mm x 16mm x 7mm Радіокомпоненти Pinout & Hardware Features
: Counting objects passing on an assembly line. Fc 51 Ir Sensor Datasheet
Detection range varies with object color and reflectivity. Black objects absorb IR and will be detected only at much closer distances (e.g., 2-5 cm), while white objects can be detected up to 30 cm. Black objects absorb IR and will be detected
Unlike ultrasonic sensors, it cannot provide an exact distance measurement; it only indicates if an object is within the preset threshold. Typical Applications Fc 51 Ir Sensor Datasheet
