5 PCS TCRT5000 Infrared Reflective Sensor IR Photoelectric Switch Barrier Line Obstacle Avoidance Module Lines Follow Occupation Avoiding Module for Arduino

Description: TCRT5000 infrared sensor emits infrared emitting diode continuously, when no infrared rays are emitted or reflected back, but the strength is not large enough - the phototransistor has been turned into the off state and the output terminal of the module is high, indicating that the diode has been turned in the off state; in the object can be detected within the detection range - and the intensity of the reflected infrared rays is large enough - phototransistor is saturated - and the output terminal of the module is low the indicator LED lights up. Characteristic: Using TCRT5000 infrared reflection sensor The detection range: 1mm ~ 8mm apply focal length of 2.5mm The comparator output signal clean - good waveform - driving ability - more than 15mA With a multi-turn precision potentiometer adjustable sensitivity adjustment The working voltage of 3.3V ~ 5V The output format: digital switching outputs (0 and 1) Fixed screw holes for easy installation Small board size: 32 x 14 mm/ 12.6 x 5.5 inch Using an LM393 wide voltage comparator widely used: Counter pulse data acquisition Fax paper shredder detection Obstacle detection Black and white line detection Package included: 5 x TCRT5000 Infrared Reflection Sensor Module IR Barrier Line Athletics Photoelectric Sensor
