WMYCONGCONG 10 PCS TCRT5000 Infrared Reflective Sensor Module IR Barrier Line Track Photoelectric Switch with Jumper Wires for Arduino Smart Car Robot

Specification: 1, using TCRT5000 infrared reflection sensor 2. Detection reflection distance: 1mm~25mm 3, the comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA. 4, with potentiometer adjustment sensitivity 5, working voltage 3.3V-5V 6, output form: digital switch output (0 and 1) 7, with fixed bolt holes for easy installation 8, small board PCB size: 3.2cm x 1.4cm 9, using a wide voltage LM393 comparator Usage: 1, the meter pulse data sampling 2, fax machine shredder paper detection 3, obstacle detection 4, black and white line detection Features: The infrared emitting diode of the TCRT5000 sensor continuously emits infrared rays. When the emitted infrared rays are not reflected back or reflected back but the intensity is not large enough, the infrared receiving tube is always in the off state, and the output end of the module is at a high level, indicating The diode is always off; when the detected object appears in the detection range, the infrared light is reflected back and the intensity is large enough, and the infrared receiving tube is saturated. At this time, the output end of the module is low, indicating that the diode is illuminated. Wiring: 1. VCC: Connect the positive pole of the power supply (3-5V) 2, GND: connected to the negative power supply 3, DO: TTL switch signal output 4, AO: analog signal output (different distance output different voltage, this foot can generally not be connected) Package Content: 10 * TCRT5000 Infrared Reflective IR Sensor Module 1 * 10Pin Female to Female Jumper Wire 1 * 10Pin Male to Female Jumper Wire 1 * 10Pin Male to Male Jumper Wire
