What is cell phone detector?

Projects Cell Phone Detector is a circuit that can sense the presence of any activated cell-phone nearby and gives an indication of activated cell-phone near around of it. Basically Cell-phone detector is a Frequency Detector or a Current to Voltage Converter Circuit which catches frequencies about 0.8 - 3.0GHz (Mobile band frequencies).

How is a cellphone detected by an RF detector?

A cellphone is detected by the virtue of its emitted frequency. Consider that a phone operates at a range of different frequencies. To find a mobile phone, the detector must be able to pick up a wide range of frequencies. The accuracy of the RF detector is dependent upon its sensitivity and dynamic range of the electronics.

Can I use an ordinary RF detector to detect GHz signals?

However, it is not suitable to use an ordinary RF detector that is making use of tuned LC circuits for detecting signals present in the GHz frequency band which are used in cell phones.

What is the frequency range of a cell phone?

With advancement in communication technology, the requirement of cell phones has increased dramatically. A cell phone typically transmits and receives signals in the frequency range of 0.9 to 3GHz. This article provides a simple circuit to detect the presence of an activated cell phone by detecting these signals.
