    Design of a Cell Phone Detector.
    (Kabale University, 2021) Atuheire, Gift
    In this project I have designed a cell phone detector circuit using same components such as resistors, capacitors, wires ,transistors , two ICs i.e. CA3130 op-amp & NE555 mono stable vibrator ,one LED and one piezo buzzer and de source of 12 volt. This designed cell phone detector can sense the presence of an active cell phone within its vicinity. It does this by detecting the signal produced by the cellphone and this causes the LED to blink and buzzer to sound. A BFN38 transistor is the major component incorporated within this project as an RF transistor that can amplify the low Radio frequencies hence the increase on the range compared to the other project circuits without any RF transistor
