Voice activated switch (VOX) kit will provide a switched output when it �hears� sound. Use it to key a transmitter for hands-free PTT, or turn on a tape recorder automatically when people are talking in a room. How about having your hallway or porch lights turn on at a whistle or better yet, the garage lights when you beep the horn. Kit runs on 6 to 12 VDC and drives up to 100 mA load such as a relay, tape recorder motor, or transmitter key line.
Size: 2 1/2 �x 1/2� x 1 1/4�.
