Has anybody got the Car parking sensors which have ultrasonic sensors (4 of them) to work with arduino. Here's one http://dx.com/p/car-parking-sensor-radar-kit-dc-12v-113045.

I want outdoor ultrasonic sensors and they seem to be built for that. The product page says the module is 12v but I wonder if the ultrasonic sensors themselves are 5v or 12v.

I'm interested into the post
those ultrasonic sensors will be good also to measure the water level inside water tanks

Maybe neither; some of the Murata transducers are OK with up to 40 volts

i dont know if this what you ask or something but when you say about car sensor, i imidiately struck ny this article i read a while ago... heres a link

I made a blog post on doing exactly this,

I've been looking around and see a lot of hacks where you connect a micro controller to the original electronics.  But I'd like to use these sensors without the original electronics.  Instead have a simple circuit that would make the signals usable by an Arduino and have the Arduino do everything.  But I haven't found anything yet.

Anybody managed to use these parking sensors on Arduino itself, without the parking computer?
I see that all of them use just two wires. Do you think if I send a pulse of about 30-40khz on them and then switch and wait for and echo this would work?

I immediately see one problem - I will have to use resistor for sending the signal, but then the same resistor will be there when I try to read that powerless echo, so I might not detect anyrhing.

Are the ones on cars significantly better than Radio Shack part number 2760342.

Would interfacing be significantly different?

I ask both to be "that guy" who posts an alternative to answering the question, but also since I bought a bunch at store closing for 75% off and because I have access to the automotive ones.

I wouldn't think that going to a junk yard and pulling them, the harness and the controller plus paying would be easier/cheaper in the long run than getting them from (insert supplier here)
