Hi, would you be able to recommend a PIR Motion Sensor module for a Eleven R3 board? Thanks.

There's a few out there - the points of difference will be the operation voltage and the angle of view. If you're looking for the simplest electrical connection, you'll need one with a simple <=5V logic output. Example:

If you're interested in connecting more than one PIR you may find our new shield of interest:

Thanks for your reply & information. I'll give one of simple module a try first.

Hi All I need I little help please, im looking for a sketch that can do the following, any help would be much appreciated

what I want to be able to drive a relay with an OUTPUT that is activated buy a PIR motion detector INPUT and deactivated with the use of a reed switch input

any ideas

Without knowing exactly what hardware you have it's a little difficult to say, however your sketch will monitor a digital input (connected to the signal from the PIR) and when it goes HIGH your board will be programmed to do something - until a signal comes from the reed switch (connected to another digital input).

If you're new to the world of Arduino we recommend a book such as "Arduino Workshop" which covers these topics and much more:
