在工业检测、家电控制等应用场合,红外传感技术占有很重要的地位、早期的红外接收器,一般均采用分立器件及专用红外接收集成块,如upc1373.cx20106等。这种电路结构不但体积大,成本高,并且电路板设计及装配工艺也很考究,一般均需加屏蔽等。使用很不方便。90年代初,日本(株)光电子工业研究所推出的HC-377微型红外接收器专用模块,是把通用红外接收集成电路集成在一块5×5.7mm的印板上,并辅以少量的外围元件而成。该模块采用金属外壳,既可屏蔽,又可固定,
In industrial testing, appliance control and other applications, infrared sensing technology occupies a very important position, the early infrared receiver, are generally used discrete devices and special infrared receiver manifold, such as upc1373.cx20106. This circuit structure is not only bulky, high cost, and circuit board design and assembly process is also very elegant, generally need to add shielding and so on. Very inconvenient to use. Early 90s, Japan’s Institute of Optoelectronics Technology introduced HC-377 miniature infrared receiver dedicated module is integrated infrared receiver integrated circuit integrated in a 5 × 5.7mm plate, supplemented by a small amount of peripheral components And into. The module uses a metal shell, both shield, but also fixed,
