G+_Rud Dog Posted January 15, 2016 Author Share Posted January 15, 2016 Is there a sensor which can sense beyond a wall with out putting holes in said wall? Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted January 15, 2016 Share Posted January 15, 2016 Rudy Trujillo Do you mean sense through a wall? If so, no. Link to comment Share on other sites More sharing options...

G+_Black Merc Posted January 15, 2016 Share Posted January 15, 2016 Their are microwave based motion detectors out there(Walmart front door). Some sold on eBay claim ranges of 30m 12v (convertable/ motorcycle alarm sys.)(breadboard ready). Research people! Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted January 15, 2016 Author Share Posted January 15, 2016 Short of seriousness you are Mr Hobbins;) The idea is to have sensors mounted around the garage area and front door sensing motion. If they could be mounted on the inside wall with out alerting to their presence it would be a game changer. Really don't want a "ready in one minute human" just sensing their motion would be sufficient. Jeez. Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted January 15, 2016 Author Share Posted January 15, 2016 As for research have invested most of this day on another search a light switch that can be programmed from a browser calendar interface. Simply click on time-on time-off and days of the week. The programmable switches with the tiny window for on switch programming are a pain in the Hobbins. See if you can find that one real fast.

G+_610GARAGE Posted January 15, 2016 Share Posted January 15, 2016 Black Merc But isn't that just motion sensor, not a rangefinder. Link to comment Share on other sites More sharing options...

G+_Steve Martin Posted January 15, 2016 Share Posted January 15, 2016 Wayne Hobbins Actually I don't think the children thing is a problem because the cars engine is likely to protect the lower half of your body. I'd just turn it off whenever you children enter the garage. Also works as a rat and mouse deterent. Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted January 15, 2016 Share Posted January 15, 2016 Wayne Hobbins The ones that are in the motion activated lights are infrared. A quick google however shows that the ones used for the automatic doors are microwave. But that is just a motion sensor. I would also ponder if they would work well on metal, or if they are a meat only sensor. You guys do know that the military uses a big microwave for crowd deterrent. Right? It just heats up your skin slightly and makes it feel like you're on fire (or something). So this aint that much of crazy talk. :) Microwave motion sensor: http://www.ebay.com/itm/WB-4001U-24-125GHz-Universal-Microwave-Motion-Sensor-for-Automatic-Door-Elevator-/111276594218 Link to comment Share on other sites More sharing options...
G+_Black Merc Posted January 15, 2016 Share Posted January 15, 2016 610bob a few that I have found have IF outputs that can be used for range determination. A good ham radio operator could help you from that point. Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted January 15, 2016 Author Share Posted January 15, 2016 Yeah Mr Hobbins I am afraid a judge would have a slight tendency to rule in favor of those "feeling slightly on fire". These sensors would tell me if my dog was barking at something 4 foot or under or above with lights/sounds being activated in case of animal or human outside the front of the house.

G+_Black Merc Posted January 15, 2016 Share Posted January 15, 2016 Found the page of one microwave based unit that has the IF output I mentioned. https://www.parallax.com/product/32213 Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted January 15, 2016 Author Share Posted January 15, 2016 Black Mec, that is it! Unfortunately will have to settle for my dog barking to get me off my butt. Those are expensive. Link to comment Share on other sites More sharing options...
G+_Black Merc Posted January 15, 2016 Share Posted January 15, 2016 WARNING TO THE REST!... what do you expect? Stuff for free! When the thing was originally built, I'll bet they were not thinking for your designs. THAT'S what prototyping is ! Its going to be ugly as sin, a jumble of parts that do a function you want. Paint it later, but make it work. Link to comment Share on other sites More sharing options...
G+_Black Merc Posted January 16, 2016 Share Posted January 16, 2016 A Cheaper unit I found on eBay for $10 (from china, month shipping time) may not have IF out. I had to dig for a month to find... don't have the link handy. The first 8088 processor chip cost $x00,000 to make, the rest were pocket change. Point being, the first device you make will cost you a chunk. Link to comment Share on other sites More sharing options...
