This is a simple electronics science project made for school children. This will be useful for those doing notional level projects. In this project it means that . It is to detect the presence of a human and issue an alarm. This circuit requires no human touch. Human presence is detected by coils made of copper wire. For this, these signals are boosted with the help of a Touch sensor module. Then its output is fed to a buzzer. Buzzer alarm is issued. A 9v battery is used to power it.
electronics components need:-
hw 9v battery
bc 547 transistor
buzzer
LM 7805 regulator
switch
wire
Copper wire 20 terns ×3
touch sensor TTP 223
