RE: Motion Sensors

["Ian B" <Ian@xxxxxxx>]

I found this exact problem and used a beam break from Maplins. I found
there
were problems with HV not noticing the change in state if it was doing
something else at the time. I got round this by making a simple signal
extender. Works a treat now and there are details on my site under my
house
and projects/baby paws.
