Incoming and Outgoing Signal Detector

About: start exploring electronics with electronicjail

can you detect mobile signals?

Step 1: Circuit for the Detector

components used :

IL386N IC

10uf 50v capacitor

led

antenna

5v dc source

Step 2: Overview

The IC used here is a low voltage audio power ampllifier IC which is suitable for battery powered devices like radios ,guitar etc....It has a single amplifier where we are feeding the signal from the antenna and gets the amplified signal out at the pin 5 of the IC which is the output of the amplifier.Since the output of the amplifier is connected to the led it starts glowing when there is a signal detected by the antenna.
