Cell Phone Detector Circuit Using Ca3130. At the heart of this overhead detector fire alarm circuit is a precision integrated temperature sensor type lm35. This handy mobile bug or cell phone detector pocket size mobile transmission detector or sniffer can sense the presence.
The first circuit of the cell phone detector is a simple implementation using an op amp and a few other passive components. Capacitors 22pf x 2 0 22nf 47pf 100µf. When the cell phone detector signal is detected the output of ic becomes high and low alternately according to the frequency of the signal as indicated by the led.
