ELM339光电器件的LED-电路板指示器阵列发光条条形图规格书PDF中文资料

描述 Description

The ELM339 is a complete remote control decoder in an 8 pin package. With the addition of a standard infrared receiver module, three individual outputs can be simultaneously controlled using a television remote control transmitter.

This circuit responds to Sony™ television control codes, chosen because most universal remotes default to them when initially powered up. The ELM339 continuously monitors the stream of data from an infrared receiver module looking for these Sony type remote control codes. If an appropriate three digit code is detected, the selected output either turns on, turns off, or switches its state.
