Design and Evolution of a Mobile Phone Detector

Here, the work focuses on the evolution and the design of a mobile phone detector, which has the ability to pick up both outgoing and incoming mobile phone signals. This compact, pocket-sized mobile transmission detector has a range of 1.5 meters to detect the presence of the active mobile cell phone. Because of this technique, it might be helpful in prohibiting the usage of cell phones in the exam rooms, private spaces, gas stations, etc. Moreover, some illegal practices like spying, unauthorized video transmission can also be easily detected by this. The circuit surely can identify both the incoming and the outgoing calls, SMS messages, and WhatsApp messages, also while the phone is in quite mode or do not disturb mode. When the bug senses an active mobile phone's radio frequency (RF) transmission, it begins to emit an alarm-like beep sound and blinks its light-emitting diode (LED). Up till the signal transmission is stopped, the alarm sounds.
