I acquired one of the Parallax radar motion detectors to experiment with. Then I decided to buy the cheap Chinese units, lacking the backboard, and I developed the backboard myself (saves about $28.00). That works fine, and I've got range out to about 15 feet.
But it occurs to me that many transmitters will transmit higher power if they can be supplied a higher power supply voltage. If I could get away with that, I might be able to get a little more range. I am curious as to whether or not anyone out there has successfully overpowered one of these, and if so, at what voltage. I could find out myself, but that's called destructive testing, which I'd rather avoid.
Thanks in advance for any insights.
