光敏传感器是一种光电变换器件。它的结构如图1所示。这种传感器是将发光元件(发光二极管)和受光元件(光晶体管)装配在同一个外壳里。被检测体通过光路时,
Photosensitive sensor is a photoelectric conversion device. Its structure as shown in Figure 1. In this sensor, the light-emitting element (light-emitting diode) and the light-receiving element (phototransistor) are mounted in the same housing. When the object to be detected passes through the optical path,
