Simple Lie Detector Circuit using Transistors Circuit Diagram and Explanation: Let’s not jump into the circuit diagram straight away. Give yourself a minute to think how this Lie Detector Circuit would actually be. So we have two LED’s which has to be turned on or turned off based on the resistance measured (it’s related with moisture) between two finger. Portable Lie Detector Circuit and its Working How the Lie Detector Circuit Works. The schematic circuit diagram of the Lie Detector is shown in the below figure. This entire system consists of three transistors TR1, TR2 and TR3, two LED lights L1 & L2, a capacitor C, five resistors R1, R2, R3, R4 & R5 and finally a variable resistor VR1. Lie Detector Circuit ElectroSchematics Length of time to measure the skin resistance is determined by R5, C2 and C3. Until such time elapses, the lie detector gives no indication although diodes D1 and D3 provide a rapid response of the circuit.
