Cell phones typically send and receive signals in the frequency range 0.9 to 3GHz. This article provides a simple circuit that detects the presence of an activated mobile phone by detecting these signals.
The basic principle of the mobile phone detector circuit is to detect radio frequency signals. In Schottky diode circuits, Schottky semiconductors are used to detect mobile phone signals because of their unique properties of being able to correct low-frequency signals with low noise rates. When an inductor is placed near an RF signal source, it receives the signal through mutual inductance. This signal is rectified by a Schottky diode. This low-power signal can be amplified and used to power any indicator light, such as an LED in this case.
