The WSG106 is a Lie Detector Electronic Kit manufactured by Velleman. The kit is powered by one 9V battery and includes two diodes. It is designed to detect changes in the electrical response of a person’s skin as they answer questions, thus helping to determine if the person is telling the truth. It includes an amplifier circuit, a buzzer, a volume control, and a sensitivity control. Additionally, the kit includes all the necessary components, such as resistors, capacitors, and opto-couplers, which makes it suitable for easy assembly and operation. The WSG106 kit is suitable for educational, assembly, and experimental use, and can be used to detect lies as part of a psychology experiment or in the field of interrogation analysis.
