Description This infrared sensor emits infrared using infrared emitting diodes, when no infrared rays are reflected back, the phototransistor is put in the off state, and the output terminal of the module becomes high, indicating that the diode is in the off state. If the object is within detection range, and the intensity of the reflected infrared rays is large enough, the phototransistor becomes saturated, and the output terminal of the module is low, which then lights the LED.
Features:
1. Uses infrared reflective sensor TCRT5000 technology 2. The detection distance: 1mm ~ 8mm with focal distance of 2.5mm 3. The comparator output signal is clean, has a good waveform, with a driving ability of more than 15mA 4. With a multi-turn precision potentiometer with highly accurate adjustable sensitivity 5. Working voltage: 3.3V-5V 6. The output format: digital (0 and 1) 7. fixed bolt holes for easy installation 8. PCB board dimensions: 3.2cm x 1.4cm 9. Uses a wide voltage LM393 comparator
Functions: 1. Meter pulse data sampling 2. Fax paper shredders detection 3. Obstacle detection 4. Black and white line detection Package includes:
