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.

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)
