I need a US based ONLY skilled hobbyist to assemble and thoroughly test a USB or AC powered, waterproof, ultrasonic device with sensor, capable of sensing obstacles up to a distance of 2 or 3 meters. Adjustable distance is mandatory when object is closer than distance set, then alarm beeps a few times. Minimum distance for alerts 2 inches-can discuss. So if I set for let's say 2 inches and am (my car) closer than 2 inches, buzzer goes off. Only measuring if something is closer than limit set. The sensor should come with a buzzer/beep feature for alerting upon the detection of obstacles in this case my car pulling up too close to garage. **Bugs, weather, rain, changes in lighting should not set tge buzzer off. Should he a solid object that lingers for one second or so.. If I am too close need it to beep. This is so I do not hit the front corner of car on garage trim frame. **Be nice if the most up to date affordable sensor was used as opposed to kit projects going back 10 years using same sensor. On off switch required and LED readout of distance set. - Accuracy up to 2 inches. ******I know they sell such kits on Alibaba and Amazon and Temu that are to be assembled. These may not have the most up-to-date sensor, connections that are best for the recommended power supply and not in a case that is waterproof. Also, perhaps the coding is not where it needs to be in order to meet my requirements. It is OK to buy one of these kits and tailor it appropriately. Be great to adjust angle of sensor but perhaps could do this with a wedge I make or shims. Will be mounted on outside of garage trim about 2 feet up from ground. Intend to power by a transformer or USB adapter- you determine. Cord will be run about 25 feet to outlet. You can exclude power supply from cost and the long cable which I can obtain. -I do not expect parts to cost more than $50, but am willing to talk about this. Bid should include price of parts, and $15 shipping charge within US to North Carolina. I am a retired person. Will use this only for personal use and not duplication or resale However, schematics, part numbers,where purchased and instructions are to be provided as are videos of testing and finished product. Ideal skills: US based person ONLY - Electronics or hobbyist: Building and testing sensors or related projects - Knowledge in waterproofing electronic devices - Ability to integrate a buzzer/beep feature Project requirements: US based freelancer ONLY. - Waterproof cased ultrasonic sensor construction for outdoor mounting - Sensor capable of obstacle detection from 2cm up to 3 meters - USB compatible power supply - Integration of a buzzer for detection alerts -Thorough testing with video results - Person can communicate well in writing, email and phone -List a few past projects even if you did them for your own use -It is OK to learn as you go on this project but have strong ability to research and ask questions on various forums, speak to companies on perhaps their sensor types and come up with a plan ..
Take some time to learn about writing in paragraph form so your book is readable.
I recommend you take a look at sensors used on today's automobiles. They are reliable and inexpensive, not cheap.
You can already buy off the shelf vehicle back-up sensor systems. What does this do that they don't?
Not backing up. Am going forward. Two cars fit in garage but it is tight . For my car on right of garage it takes a sharp left turn into garage. My garage is perpendicular to driveway. So am trying to avoid hitting the front bumper, fender yet again. Prob can be easily solved by taking my time and paying more attention OR hanging a pool noodle or boat bumper or the like on outside garage trim. But wife and I have hit garage about 4 times total. Each hit costs quite a bit to fix car. Garage never has damage. Tx
It formatted it this way for some reason when pasted. Was nicely formatted before paste. Sorry.
? So? Install it in front. Or are you thinking of mounting this in the garage to detect the car?
Many times in industry I see mirrors installed for this and similar reasons. Nice thing about them they do not need power.
Some cars come with 360° camera system that exactly shows you where you will next, you even can buy that as an addon
