A "retired" product is one that will no longer be brought back in stock.
Description
The design of this circuit is based around an Integrated Circuit that ensures very high sensitivity. Any sound will be captured by the microphone and will activate the output relay which will remain activated while there is sound. The relay can handle loads of up to 3A. It has many applications such as controlling a tape recorder in seminars and classrooms (the recorder will start recording only when the speaker starts speaking).
