Hello,

PIR =Passive Infrared.

I am very new to this forum.
I am trying to connect PIR with atmega32.
I am using proteus software to circuit design.There I can't find PIR.

Can anyone please give me the circuit diagram to connect PIR with atmega32?

Idea of the project:
If any people appears in the range of that PIR a led will be lightened.

Thank you all guys.

Post the datasheet of the PIR you have in mind to use. Not knowing the type of signal the PIR send out once triggered, I am anable to give you any suggestion.

The fragmentary data sheet indicates a TTL level pulse out (0 & 5 volt levels), suitable for connection to a microprocessor. There is no pinout, though.

hi,
My goooooooooggle is better than yours !:)

follow the link http://www.electronics123.net/amazon/datasheet/kc7783R.pdf
then you can use your Pir from 3 methods:
1) for a led a small Tr an the led+ a 220r in the collector

2) the Pir drive directly a circuit across a mosfet tr or if you are classical a npn-tr low signal and a relay.

3) put the portx.y of your m32 in input with (config portx.y =input in Bascom) then read the port with Var=pinx.y
"Bon courage"

you must desing your own circuit for Proteus it is very easy to do and add it in your user lib (I use a professioal version)
