TCRT5000 Infrared Reflective Switch IR Barrier Line Track Sensor ModuleFeatures TCRT5000 sensor of infrared emission diode constantly launch infrared the infrared ray is emitted when the intensity of reflected back has not been reflected or but is not big enough the light activated triode has been in the off state the output end of the module at this time for the high level indicating diode has been put out state Detected objects appear within the scope of testing infrared light is reflected back and strength is enough big light activated triode saturation at this time the output of the module for the low level instructs the diode lights Specification 1 Using infrared reflection sensors TCRT50002 Test reflection distance 1mm to 25mm3 Clean and the comparator output signal waveform driving ability is strong for more than 15 ma 4 With many adjustable precision potentiometer to adjust sensitivity5 The working voltage of 3 3V to 5V6 Output form digital switch output 0 and 1 7 Has a fixed bolt hole convenient installation8 Small board PCB size 3 1cm x 1 4cm9 The LM393 use of wide voltage comparator10 Applications 1 the electricity meter pulse data sampling11 Fax machine shredder paper detection12 Obstacle detection13 Black and white line detectionPackage included 1 x TCRT5000 Module
