An optical reflective sensor is an advanced electronic device blending an IR LED and an IR photo-transistor for precise detection. The IR LED emits light, bouncing back to activate the photo-transistor and increase current flow, effectively signaling the presence of objects.The Adafruit STEMMA Reflective Photo Interrupt Sensor offers a hassle-free setup with no soldering needed. Power it with 3 to 5V DC and utilize the output pin to swiftly detect reflective surfaces. A green LED indicates power, while a red LED lights up when the phototransistor is active, both of which can be disabled.Specifications include a TCRT1000 right-angle sensor module, adjustable IR emitter via a potentiometer (1mA to 100mA range), and a 10K pullup-bias phototransistor. When IR light isn't detected, the output signal remains high; with reflection, the voltage drops towards 0V. The device's plug-and-play JST PH input connector enables solderless integration with various electronics platforms. https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2025-11-11 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2025-12-04 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2025-12-20 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-01-24 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-01-29 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-02-01 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-03-15 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-03-18 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-04-08 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-04-16 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-04-25 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-05-03 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-05-15 https://elecena.pl/product/29497902/adafruit-stemma-reflective-photo-interrupt-sensor-tcrt1000 2026-07-01
