Re: motion detection PIR

["Frank Mc Alinden" <armagh@xxxxxxx>]

Hi Amar
               
I wouldnt go using a microwave sensor in a flat as it can
pick up movement thru walls etc....... (flat next door )A 360 degree
would
need to be mounted in the centre  of a room to give proper coverage
,the 180
degree is the best bet IMO and mount it such that someone walking into
a
room walks acroos the face so to speak and not directly into the
sensor.................
