Abstract
ABSTRACT
This project is based on construction and testing of cellphone detector. Cellphone detector is electronic circuit that detected the incoming and outgoing calls and video transmission even if the mobile phone is kept in the silent mode.it consist of two stage, comparator stage that compared radio frequency (RF) signal with the reference signal using op amp (LM358) and the other stage using monostable multivibrator ( 555 timer ) when triggering by the output transistor the buzzer started to alarm a beep sound immediately, it consists of various components, like resistor that used to resist the flow of current and also a capacitor that perform different types of function in a circuit such as blocking direct current while allowing alternating current to pass or smooth the output from a power supply. And transistor also is the one of most crucial components of an electronic circuit.
