Two sensors inputted to an OR gate made out of MOSFET transistors using HEF4007 IC chip. The first one is for heat, done using a thermistor and a comparator configuration using UA741 OpAmp; the other one is similar but for motion with an LDR instead. Once either sensor is triggered, the gate output voltage would turn on a buzzer, and its amplified current turns on a DC motor whose speed is tuned by a potentiometer.
