Cell Phone Detector Circuit Using Ca3130. 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. Also read the post.
At the heart of this overhead detector fire alarm circuit is a precision integrated temperature sensor type lm35. 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. Simple cell phone detector circuit.
Capacitors 22pf x 2 0 22nf 47pf 100µf.
Resistors 2 2mω x 2 100kω 1kω. 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. At the heart of this overhead detector fire alarm circuit is a precision integrated temperature sensor type lm35. The first circuit of the cell phone detector is a simple implementation using an op amp and a few other passive components.
