LF0038E ir digital receiver is a small infrared receive unit , the key component in the inside part is full integrated IR Receiver . This component packs high –performance PIN Photo Diode together with IC chip which has the function of enlargement and demodulation by epoxy resin ,By this , LF0038E ir digital receiver can resist various kinds of visiable light interferences and electromagnetic interference . With the interior part set with power supply IC filter circuit , it can effectively solve the interference produced through extending the receiving circuit . it can makes remote control more flexbile and more convenient.
