Hi, I was wondering if there are any (I didn't find any using google) do it yourself descriptions for a microwave perimeter intrusion detector/ alarm?
From the pictures I've seen of opened up ones, the antennas used seem pretty simple. Electronincs shouldn't be too hard either.
Application is for protecting an agricultural area of about 3 ha, bound by 6 straight lines and corners.
Has anyone ever come across some useful links?
Would be very helpful, thanks
