TCRT5000 Infrared Reflective Sensor Module IR Barrier Line Track Photoelectric Switch.

描述

TCRT5000 Infrared Reflective Sensor Module IR Barrier Line Track Photoelectric Switch Description: TCRT5000 infrared sensor emits infrared emitting diode continuously when no infrared rays emitted or reflected back is reflected back but the strength is not large enough- the phototransistor has been in the off state- and the output terminal of the module is high- indicating that the diode has been in the off state; in the object to be detected within the detection range- and the intensity of the reflected infrared rays is large enough- phototransistor saturated- and the output terminal of the module is low- the indicator LED is lit. Feature: Using infrared reflective sensor TCRT5000 The detection distance: 1mm ~ 8mm apply focal distance 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) A fixed bolt holes for easy installation A small PCB board size: 3.2 x 1.4cm Using a wide voltage LM393 comparator Usage: Meter pulse data sampling Fax paper shredders detection Obstacle detection Black and white line detection Package included: 1 x TCRT5000 infrared reflective sensor module
