TCRT5000 Reflective IR sensor photoelectric switch

The TCRT5000 is a compact, reflective optical sensor that integrates an infrared (IR) emitter (blue LED) and a phototransistor receiver (black component) into a single leaded package designed to block out visible light. It functions by emitting IR light from the transmitter; if an object passes within range, the light reflects back into the phototransistor, altering the electrical current flow to signal a detection
