A flip of 51 puts the system in action. Power for the circuit is captured from the ignition switch, and circuit receives no power until the ignition switch is closed. When the camera is turned on, the capacitor C1 is charged and the emitter follower Darlington pair (formed by Q1 and Q2) are cut, so [...]
Bridge circuit contains two resistors lOO-ohm (R3 and R4), and two thermistors (Tl and T2). At room temperature, the resistance of T1 and 1’2 is about 2000 ohms. When they are each heated to 150 °C by an RNA 10 current, the resistance value decreases to 100 ohms. So. the four elements include a bridge [...]
