Hello guys. i am planning on working with some ultrasonic range finding sensors on the following weeks, for two projects
- measure the fuel level, in a fuel tank (tank wall is very thin , about 10mm or something)
2)develop a parking sensor module.
I have no prevous experiance on that subject, and so i have no idea, if the sensors will be able to work, if a thin metal/plastic is in front of it…
for (1) the reason is that the sensors, will be mounted above the fuel tank, so they will have to pass through the walls… but with a quick search around the internet, it seems that this is the way to do it…
for (2), i have seen that OEM car makers, drill holes on the bumpers… and so i wonder, if ultrasonic works with a thin metal layer, why not with a thin plastic??
Also, on the specs of some sensors i see something like “blind distance = 2cm”… does it have anything to do?? thanks!!
