How to Make a Simple Motion Sensor Led Light (Revisited) (PIR)

Hi Again!

Now, I am here with a new Model of PIR Simple Motion Sensor Led Light!

The Previous Instructable had Portability Issues and a Resistor Problem.

In this Version i have made it more Compact and Easy to keep with a little improvement which i got from comment.

Kits would be soon available for Grabs.

Message me to Book one. Price would be Only 7$ + Shipping ( would be estimated according to country)

Do Vote me for Home Automation Contest :)

Let's Make!

First of all List of Parts Required:

1) PIR

2) PCB

3) BC547

4) 1k

5) Screw Terminal (2 Pin)

6) 4 White Leds.

7) Long Male Header (3Pin)

Sorry.. forgot to click pictures of parts.

But you could search the part image on google ;)

I Slightly Modified it from my previous instructable.

Now it has 1k in between transistor and pir. by which it reduces the drop out voltage of transistor.

Taking measurments of PIR Was a Lot difficult but the measurment tool in eagle cad, made my day.

It helped me take a good measurments and helped to find the middle of the board

See Picture how i figured out the size and where to place components.

If you don't know how to do this then Please see these steps in my previous Instructable Here.

Solder the Screw Terminal...

Solder BC547...

Remember The Position.

Solder the Resistor...

Now Solder Those Leds.

No Need to Drill holes for it.

Because these would be soldered directly to board.

Now Solder The Header to the Board and then with the other header on the PIR.

That's it!

We have made a Cool Looking Compact Motion sensor Light.

Now Power It ON with 12v Regulator.

Give it a warm up time of 20 sec.

Now it should light up leds when motion is sensed.
