DIY – LIE DETECTOR – SOLDERING KIT(Set)

Price exGST: $ 11.50

Price incGST: $ 12.65

The kit consists of three transistors (TR1 to TR3), a capacitor (C1), two lights or LEDs (L1 & L2), five resistors (R1 to R5), and a variable resistor (VR1). Suitable transistors to use are BC547, BC548 or BC549, or any other small NPN transistor. This circuit is based on the fact that a person’s skin resistance changes when they sweat (sweating because they’re lying). Attach the probe wires onto the palm. Green light is on when the tested stays cool. Red light comes on when the tested starts to sweat. Soldering required. Battery not included.
