This kit combines two kits in one - a powerful two stage FM transmitter and a sound activated switch.

Sound turns on the transmitter, which might be a good way to hear a baby waking up. The transmitter can be monitored with any FM radio, Walkman etc. Simply tune the receiver to a clear spot on the FM band (between 88 and 108 MHz) and then tune in the transmitter. A neat way to catch a thief in another room or garage. The volume of sound needed to trigger the circuit is adjustable; can be set to very sensitive pickup.. The two stage transmitter has good range and the circuit powers down unless it "hears" sounds; reactivates with a sound.

Soldering Iron, Solder, and basic tools are required to complete this kit - (Not included)
QTY: 1 Kit - Includes PC Board, Components and Instruction Sheet / Guide.
