Cell Phone Detector Project For Students

Circuit Diagram :-







Circuit Layout :- 







Components List :-

  • 3x3 inch copper clad PCB - 1 Piece
  • CA3130 IC - 1 Piece
  • BC 548 Transistor - 1 Piece
  • 5mm Led - 1 Piece
  • 0.22uf capacitor - 1 Piece
  • 100 uf capacitor - 1 piece
  • 47 pf capacitor - 1 Piece
  • 9v Battery with cap - 1 Piece
  • 1x2 green terminal - 1 Piece
  • 100 kilo ohm resistor - 1 Piece
  • 2.2 Mega ohm resistor - 2 Piece
  • 1 kilo ohm resistor - 1 Piece



Working:-

There is natural electromagnetic field around the capacitor caused by 50Hz electric wiring. When the mobile fan radiates high frequency radiation, capacitor oscillates and release energy in the inputs of IC. This oscillation is indicating by Flashing of LED.

Components using in this projects are :- UM66 ic - 1 BC 547 - 1 Glass epoxy board - 1 Self lock switch - 1 1x2 Screw terminal - 1 Speaker - 1 100 ohm resistor - 1 9v battery + cap - 1 UM66T  is a melody IC. It is basically intended for use in Telephones, toys, bells etc. There is one inbuilt tone and a beat generator in this ic. The tone producer is a programmed separator which produces certain frequencies. These frequencies are a part of the oscillator frequency as well as the beat generator is also a programmed divider which includes 15 available beats. Four beats of these can be selected. When power is turned on, then melody begins from the first note as well as melody generator is reset. The external npn transistor which is connected to the output of UM66 can drive to speaker. There are so many versions of UM66T are available today which produce tone of different songs. For example, UM66T01 generates tone for songs ‘Jingle bells’, ‘Santa Clau...
