DTMF-8

DTMF-8 DTMF-8 is an inexpensive, self contained, DTMF (dual tone multiple frequency) decoder board which permits users to control remotely, via radio or other audio producing source, the on or off state of eight devices. For larger applications several DTMF-8 boards can be attached to the same control audio source to control dozens of devices. DTMF-8 supports four modes of operation.
