Light Beam Receiver/Transmitter with case (Special Deal)

Kit includes separate receiver and transmitter modules for unlimited possibilities. Transmits a modulated infra-red 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 mic and is very sensitive. The receiver employs an IR PIN diode detector and puts out enough power to drive any speaker 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. Don?t forget our slick matching case set with red IR end panel.
