But I figured it would be very tedious to allign it. I checked, I could enclose the laser, reciever, and mirrors inside the main fence posts, just drilling holes to pass the beams so you woundlt even know it was there if it was visible, unless you noticed when you breached it. Touch \ laser could go right through or over the gates. Heck, I wouldnt mind just powering the cable with 220 and letting the intruders screams alert me, but legallity gets in the way.Įither of the cable ideas however leave me having to also alarm the gates. I had also thought about isolating the cable from the fence, powering the cable and grounding the fence, so when the two touch, it trips the sensor. That gives me another option I suppose, stringing a thin steel cable above the post, with a pressure switch on one side, so if someone pushes down on the cable, it pulls the switch. Maybe you guys can give me some pointers, or just tell me its impossible.
Unfortunately I dont know much about capacitive touch other than plug and play chips. I definitely dont want motion sensors \ PIR because I want this to be a 99% accurate system.
Im not horribly paranoid, just some activity in the neighborhood got me thinking, and im in need of a project. If not, I wonder what would happen if I energized the bar with a mild DC source, like 5VDC, not enough to even feel, but could I monitor it and sense a dip when someone touched the pole?
Would it even work with the fence being grounded? If not, what if I insulated the top bar, which would be doable, it would then not be grounded, could I build a CT sensor that would Is there a way to build a capacitive touch sensor that would work with such a large object? That way when someone touched the gate, or grabbed the fence to jump it, it would trip. I could try and bounce a beam around with mirrors, but seems like it would be very finicky to adjust. Im working on IR laser trip beams for the front yard, the back yard is fenced. I've been working on perimiter security on my house.
