Product Usage:1. Pulse data sampling of watt-hour meter2. Facsimile paper shredder paper detection3. Obstacle detection4. Black and white line detectionproduct description:1. Using TCRT5000 infrared reflection sensor2. Detection reflection distance: 1mm~25mm applicable3. Working voltage: 5V4. Output form: digital signal (0 and 1)5. Equipped with fixing bolt holes for easy installation6. Small board PCB size: 3.5cm x 1cm7. Single weight: 4.5gFeatures: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 strong enough, the infrared receiving tube is always in the off state, and the output terminal of the module is at low level, indicating The diode is always in the off state; when the detected object appears in the detection range, the infrared is reflected back and the intensity is large enough, the infrared receiving tube is saturated, and the output terminal of the module is high at this time, indicating that the diode is lit.Wiring:1. VCC: Connect to the positive pole of the power supply (5V)2. GND: connect to the negative pole of the power supply3. OUT: high/low level switch signal (digital signal 0 and 1)
