Abstract:

Mobile phone detection has a variety of applications, from security systems to personal alerts.

This paper presents a hardware-based mobile phone detector that utilizes an Arduino microcontroller, an operational amplifier (op-amp), and an antenna to detect mobile phone signals.

The system is designed to detect incoming calls by capturing electromagnetic signals emitted by mobile phones.

The antenna captures these signals and sends them to the op-amp, which amplifies the signal for further processing.

The amplified signal is then read by the Arduino, which processes the data and activates an indicator, such as an LED or buzzer, to alert the user of an incoming call.

The key components of the system include the antenna for signal capture, the op-amp for signal amplification, and the Arduino for signal processing and indicator control.

The system's design is aimed at achieving a reliable detection mechanism with minimal hardware complexity.

Experimental results demonstrate the effectiveness of the system in detecting mobile phone signals with a high degree of accuracy.

This approach provides a cost-effective solution for mobile phone detection with potential applications in security, monitoring, and personal alert systems.

Future work includes optimizing the sensitivity and range of the detector to enhance its applicability in various environments.
