CELL PHONE DETECTOR CIRCUIT

on Saturday, 5 October 2013
In our previous post we have seen the LDR sensor Circuit and which was pretty easy one, now in this post we will go further with Cell Phone Detector Circuit.
The circuit can detect the incoming and outgoing calls and SMS even if the phone is in silent mode. When it detects the presence, alerts by beep sound using buzzer. It can detect the presence within one and half meter range.
With this circuit we can be familiar with IC opamp, 555timer. Its a good practice for beginners to wire this circuit on the breadboard and verify its output.
Look at the circuit below

cellphone detector circuit














Note:Input voltage  9-12v(tested with 9v as well as 12v).
 We can replace the antenna with 2meters of wire(any gauge).

I have tested this circuit and it works well, you can watch video below.

sir how can we simulate this ckt in isis proteus as we don't have any cell phone in it.

We cannot simulate this ckt. I made real hardware to check this ckt and it worked fine.

The HUMANOID robotic ARM using pic microcontroller The purpose of the HUMANOID robotic ARM project is to implement the position control and vision control on the robotic arm. Which in my opinion is one of the best things happening and even KLDS and http://microcontrollerslab.com/ talked about this.

You should also check The Engineering Projects because they have posted a lot of Arduino Projects and PIC Mirocontroller Projects and have also designed many new Proteus Tutorials. I hope you guys are gonna like them.
