This kit can be great fun at parties. Lie and an audible tone
will change, the more you lie the louder the tone. When you
lie your hands sweat, this kit allows you to measure these
changes. We measure Galvanic Skin Resistance. Only a very slight amount of change will cause the
tone to increase in frequency.
Power requirement 9 Volt battery or 6 to 12v DC.
PCB size: .8" x 1.2"
