DZS Elec 5PCS TCRT5000 Infrared Reflective Switch IR Barrier Line Track Sensor Module and 20Pin 20cm Cables Line Jumper Female to Female Kit for Arduino Raspberry Pi Smart Car Robot

Features: Infrared Reflection Sensor Model:TCRT5000. Detection Distance: 1mm to 8mm. Focus Distance :2.5mm. Output Current: greater than 15mA. Operating Voltage: 3.3V-5V. Output form: digital switching output (0 and 1). Small board PCB size: 32 x 14mm/1.26x0.55Inches. Comparator Model: LM393. Length of Dupont Wire:20cm/7.87Inches. Package:6PCS Tracking Sensor Module,1PC 20 Pin Dupont Wire. Description: The infrared emitting diode of the TCRT5000 sensor continuously emits infrared ray. When the emitted infrared ray is not reflected back or is reflected back but not strong enough, the photosensitive triode is always in the off state. At this time, the output end of the module is at a low level, indicating that the diode is always in the out state.When the detected object appears within the detection range, the infrared ray is reflected back and the intensity is large enough, and the photosensitive transistor is saturated. At this time, the output end of the module is at a high level, indicating that the diode is lit.
