1PCS TCRT5000 Infrared Reflective Sensor IR Photoelectric Switch Barrier Line Track Module For Arduino Diode Triode Board 3 3v 2

Features: 1. Using infrared reflective sensor TCRT5000 2. Detecting the reflected distance: 1mm ~ 25mm applicable 3. The comparator output signal clean, good waveform driving ability more than 15mA. 4. With multi-turn precision potentiometer adjustable sensitivity adjustment 5. The working voltage of 3.3V-5V 6. Output format: digital switching output (0 and 1) 7. Size: 3.2cm x 1.4cm 8. Using a wide voltage LM393 comparator Application: TCRT5000 sensors continuously emit infrared emitting diodes, infrared rays emitted when not being reflected back or reflected back but the strength is not big enough, the phototransistor has been in a shutdown state, then the output modules is high, indicating diode remains off state; when the object appeared to be detected within the detection range of the infrared is reflected back and the intensity is large enough, the phototransistor saturated, then the output of the module is low, indicating the diode is lit. 1. Meter pulse data sampling 2. Fax paper shredders detection 3, obstacle detection 4, black and white line detection Package Includes: 10 * TCRT5000 avoidance module TCRT5000 infrared reflection sensor, detecting reflection distance, suitable for 1mm~25mm, comparator output, clean signal, good waveform, strong driving ability, over 15mA, with potentiometer adjustment sensitivity IR Infrared Obstacle Avoidance Sensor Module TCRT5000 Photoelectric Switch Barrier Line Track Sensor Module for Smart Car w/Cable 3.3V-5V Easily Installation:Design with bolt holes for easy installation.
