Product Description
Transmits a modulated infrared light beam up to 30 feet without lenses, up to 1/4 mile using simple lenses. Since the beam is modulated with a 30 KHz carrier (like AM radio) there is no effect from 60 Hz hum that is produced by indoor lighting. Easily transmits through windows - ideal for bugs or listening to IR television remote controls. The transmitter can use any type of mike and is very sensitive. The receiver employs an IR PIN diode detector and there is enough power to drive any loudspeaker or earphone. The PC board is cleverly scored so you can easily separate the Transmit and Receive sections so they can be used individually to transmit at one location and receive at another. Units run on 9 to 12 VDC, and will use standard 9V battery. The LB56 has been a popular kit for years, and a leading science fair project to show how you can send audio over Infrared! Comes complete with the custom case & knob set shown to give your project a great finished look. Case size: 5 W x 1 1/2 H x 5 1/4 D.
