Grahikum TCRT5000 Infrared Reflective IR Photoelectric Sensor Switch Module 3.3-5V Obstacle Avoidance Barrier Line Track Sensor Module (Pack of 10) Electronic Components Electronic Hobby Kit

The infrared emitting diode of TCRT5000 se nsor continuously emits infrared ray. When the infrared ray emitted is not reflected back or is reflected back but is not strong enough, the infrared receiving tube is always in the state of shutdown. At this time, the output end of the module is at high level and the indicating diode is always in the state of extinction. When the detected object appears in the detection range, the infrared ray is reflected back with sufficient intensity and the infrared receiving tube is saturated. At this time, the output end of the module is at a low level and the indicating diode is lit up. 1. Meter pulse data sampling 2. Fax machine shredder paper detection 3. Obstacle detection 4. Black and white line detection 1. TCRT5000 infrared reflection sensor is adopted 2. Detection reflection distance: 1mm~25mm applicable 3. comparator output, signal clean, good waveform, strong driving capacity, more than 15mA. 4. with multi - turn adjustable precision potentiometer to adjust the sensitivity 5. Operating voltage: 3.3v-5v 6. Output form: digital switch output (0 and 1) 7. Fixed bolt holes are provided for easy installation 8. PCB size of small board: 3.2cm x 1.4cm 9. Use wide voltage LM393 comparator 1. VCC: connect the positive pole of 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 voltages are output from different distances, so this pin can not be connected in general)
