Performance can be inconsistent under strong ambient light or sunlight, which may require shielding or recalibration of the sensitivity potentiometer.
. 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
Used to adjust the detection range sensitivity. Fc 51 Ir Sensor Datasheet
Emits infrared light at a specific frequency.
Adjustable from 2cm to 30cm via an onboard potentiometer. Performance can be inconsistent under strong ambient light
