Recommendations for wireless PIR

Grumpy

I thought this would be straightforward but I seem to be going round in cicles.

I live out in the sticks and it's pitch black in the evenings. As a temporary measure I would like to put a battery powered wireless PIR at the end of my drive and link it to a receiver in the woodshed, some 40m distant, to turn on the external lights on said shed hoping to prevent Mrs G fracturing something in all the potholes. I've already run power to the shed with the intention of carrying that on to the gateway at some yet to be specified time in the future.

So, I would be very grateful for any recommendations for suitable kit as Google doesn't seem to be co-operating tonight.

Many thanks.

    Legal radio links that can be installed anywhere and don't need a license are power limited to avoid causing interference to other similar uncontrolled systems.  This does tend to mean that the useful range is a bit hit and miss - and actually I'd take any quoted distance figure with a large pinch of salt - a great many things affect radio propagation and there is a tendency of the marketing types to quote the best performance ever seen when measured in ideal conditions as if it was typical.

    That said getting antennas as high as possible, and oriented the radiating elements parallel at both ends of the link and away from obstructions can go a long way to making things more reliable.
