一、什么是光耦？ 光耦合器 (Optocoupler)，亦称光电隔离器 (Opto-isolator) 或简称光耦，是一种利用光作为传输媒介，实现电信号隔离传输的半导体器件。其核心结构由集成于同一密闭封装内的发光器件（通常为红外发光二极管，即 IR LED）和光电探测器（如光电晶体 ...

When you buy an off-the-shelf automatic cat feeder, you might well expect it to do the one thing it’s supposed to do. Feed the cat. Well, at least as long as you do your part by keeping it filled with ...

Plugging right in to that eerie “they’re watching me” feeling you’re supposed to get from normal portrait paintings, Opto-Isolator is an artwork that takes the sensation into the scary, robotic 21st ...

The optocoupler board project is intended for general purpose applications where the signals are allowed to pass between two circuits without having to connect them electrically. The optocoupler board ...
