## Description

Reflective optical sensor for surface detection and line tracking in robots, combines infrared LED and phototransistor with variable analog output depending on reflection. Works optimally at 2.5 mm, emits at 950 nm, offers typical current 1 mA and includes filter to reduce the influence of ambient light.
Reflective photoelectric sensor TCRT5000, TCRT5000L, with ambient light filter.
The sensor is composed of an infrared emitting LED and a phototransistor that emits a variable analog signal depending on the reflection.
Ideal for line-following robots due to the fact that it can differentiate between white and black surfaces.
