5Pcs TCRT5000 Infrared Reflective Sensor Modules, TCRT5000 Infrared Reflective Photoelectric Switch IR Tracking Sensor Module Obstacle Avoidance Barrier Line Track

Specifications: 1. Adopt TCRT5000 infrared reflection sensor. 2. Detection reflection distance: 1mm-25mm applicable. 3. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA. 4. Adjustment sensitivity of power distribution positioner. 5. Working voltage: 3.3V-5V 6. Output form: digital switch output (0 and 1) 7. With fixing bolt holes for easy installation 8. Small board PCB size: 3.2cm x 1.4cm 9. Use wide voltage LM393 comparator Features: The infrared emitting diode of the TCRT5000 sensor continuously emits infrared rays. When the emitted infrared rays are not reflected or reflected but the intensity is not strong enough, the infrared receiving tube is always in the off state, and the output terminal of the module is at high level, indicating The diode is always off; when the detected object appears in the detection range, the infrared rays are reflected back and the intensity is large enough, and the infrared receiver tube is saturated. At this time, the output of the module is low, indicating that the diode is lit. Product Usage: 1. Pulse data sampling of watt-hour meter 2. Paper detection of fax machine shredder 3. Obstacle detection 4. Black and white line detection Wiring: 1. VCC: Connect the positive pole of the power supply (3-5V) 2. GND: connect to the negative pole of the power supply 3. DO: TTL switch signal output 4. AO: analog signal output (different distances output different voltages, this pin generally does not need to be connected). Package Includes: 5 x TCRT5000 Infrared Reflective Sensor Modules
