 Features

 

 

 Battery saving

 

    The receiver works intermittently to reduce the battery consumption. The microcomupter embedded on 

the receiver controlls the power supply for the RF circuit. In case of the microcomputer detects the 

wake-up signal during the power supplied, the microcomputer continue supplying the power until the data 

frame will be received.
