●接收頭是一種特殊的紅外接收電路，它將紅外接收管與放大電路集成在一體，體積?。ù笮∨c一只中功率三極管相當(dāng)），密封性好，靈敏度高，性?xún)r(jià)比高。它有三條管腳，分別是電源正極、電源負(fù)極以及信號(hào)輸出端，其工作電壓在5V左右，只要給它接上電源即是一個(gè)完整的紅外接收放大器，使用十分方便。
●接收頭的主要功能包括接收紅外信號(hào)、放大、選頻、解調(diào)幾大部分，因?yàn)檩斎胄盘?hào)是已經(jīng)被調(diào)制的信號(hào)，經(jīng)過(guò)它的接收、放大和解調(diào)會(huì)在輸出端直接輸出原始的信號(hào)。從而使電路達(dá)到最簡(jiǎn)化！靈敏度和抗干擾性都非常好，可以說(shuō)是一個(gè)接收紅外信號(hào)的理想裝置。
●紅外接收頭有多種稱(chēng)呼，中文叫接收頭、紅外線接收頭、紅外線接收頭、接收器，遙控接收頭等，英文全稱(chēng)為：Infrared Receiver Module，業(yè)界常將此簡(jiǎn)稱(chēng)為IRM或RCM.
