DIY HUMAN DETECTION SYSTEM AND ALARM (no Arduino)

Introduction: DIY HUMAN DETECTION SYSTEM AND ALARM (no Arduino)

About: I am an Electrical Engineer and making electronics projects, gardening, sketching, blogging, repairing gadgets, tinkering with circuits are my hobbies. Follow my instructable page and youtube for more upcoming…

IT ALWAYS HAPPEN WHEN YOU ARE IN THE ROOM AND SOMEBODY ENTERS IN YOUR HOUSE OR SHOP WITHOUT ANY NOTIFICATION...HE MAY BE A THIEF ...then here is the solution in which you are awared by an alarm system when any motion is detected..(LESS THAN 10 MINUTES PROJECT) SO LETS GET STARTED..>>

Step 1: PIR SENSOR :THE HEART COMPONENT

GRAB THE COMPONENTS..

1. pir sensor

2.npn transistor.

3.buzzer

4.power supply (5-12v)

Step 2: Solder the Components..see the Schematic.

The schematic is attached here..solder the components according to it...

->The pir has on board 3v regulator.

->Any pnp transistor will work.

->Buzzer of 5-12v dc

->Resistor is used to limit the value of currrent.

Step 3: Installing (home Made Power Supply Rectifier and 230v/9v Transformer)

once the circit is done according to given schematic ..you are on ..for sweet sleep..

NOW IF ANY BODY COMES IN THE RANGE OF SENSOR THE BUZZER WILL BEEP AND AWARE YOU...
APPLICATIONS

1. AT HOME FOR NIGHT THEFT PROTECTION.(DAY ALSO)

2. AT YOUR SHOP IF ANY ONE ENTERS IN ABSENCE OF YOU

3. BACKYARD PROTECTION

4. BUZZER CAN BE REPACED WITH RELAY FOR FURTHER AUTOMATION.(in future i will provide)

THNKS GUYS

    WHAT!! NO ARDWEENIE,NO RASPER OR MICRO-CONTROLLER!!!How will this ever fly! Thank you for having the courage to bring back a simple project without having to break the bank. None of the spoiled kids will ever grasp true electronics without starting with simple ideas like yours. Lets'watch them make this difficult.
