TCRT5000 Infrared Reflective Sensor, IR Photoelectric Switch Barrier Line Obstacle Avoidance Module 3.3V-5V Tracing Sensor Module with Jumper Wire for Arduino Smart Car Robot DIY (10PCS)

Description

Product Applications: 1. Watt-hour meter pulse data sampling 2. Fax machine shredder paper detection 3. Obstacle detection 4. Black and white line detection 5. DIY etc. Product Description: 1. Adopt the 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. Adjust the sensitivity with a potentiometer; 5. Working voltage 3.3V-5V; 6. Output form: digital switch output (0 and 1); 7. There are fixed bolt holes for easy installation; 8. Small board PCB size: 1.5X0.55X 0.7Inch /3.8X1X1.8cm(L*W*H); 9. Use a wide voltage LM393 comparator. Features: The infrared emitting tube of the TCRT5000 sensor continuously emits infrared rays. When the emitted infrared rays are not reflected back or are reflected back but the intensity is not strong enough, the infrared receiving tube is always in the off state. At this time, the output terminal of the module is at a high level. The indicator tube is always off; when the detected object appears within the detection range, the infrared light is reflected back with sufficient intensity, and the infrared receiving tube is saturated. At this time, the output terminal of the module is at a low level, and the indicator tube is lit. Wiring: 1. VCC: connected to the positive power supply (3-5V) 2. GND: connected to the power negative 3. DO: TTL switch signal output 4. AO: Analog signal output (different voltages are output at different distances, this pin can generally be left unconnected) Package Included: 10PCS TCRT5000 Infrared Reflective Sensor IR Photoelectric Switch Barrier Line Obstacle Avoidance Module. 20PCS Female to Female Dupont Jumping Wires. 20PCS Female to Male Dupont Jumping Wires.
