My First Project

Hi

I am just starting out in this whole field and I am looking for some
help. I would like to try to complete a simple project which will be
the foundation for a slightly more complicated project.

All I want to do is make a light(LED) go on when a motion sensor(IR -
PIR? Seems to be cheap and cheap is good) detects movement. If anyone
can point me in the direction of a tutorial or tell me what kind of
parts I need to get etc(obviously motion sensor + light <?led?>+ power
+ other stuff?)I would appreciate it. I have tried to find tutorials on
Google but have been unsuccessful, this may be because I am new to this
field and I don't know the "lingo" so I don't really know what to
Google.

Any help that anyone can offer will be appreciated.


Thank you

You can buy a motion detector light fixture at any hardware store.
They go on sale here for $7. Hard to imagine building one any cheaper.
That's less than you'd pay for shipping if you ordered parts.

X10 sells power line connected units and RF connected units.
I have in my hand a X-10 Powerhouse Model MS13A that is battery powered,
detects motion, turns on it's led, transmits codes to the X-10 wireless
RF receiver.

If you tried to build one from scratch, your biggest problems wouldn't
be electronic.
The ones I've seen work by using multiple Fresnel lenses to present
spatially displaced imges. As you move, those images slew across the
sensor which detects change. You'd have to learn about infrared
transparency of plastic materials, Fresnel lenses etc...then try to make
'em.

Well i was able to find this one online
http://www.mpja.com/productview.asp?product=7250+MI

there are others like this...but are you saying that i cant just plug
this into a circut board ....i have to do all the extra Fresnel lense
stuff? if so thats more complicated than i thought and i will look into
an easier project...

than you for your response

Check out http://www.hobbyengineering.com/SectionS.html They have IR
sensors with lenses, plus other things as well. Prices are very reasonable
too.
