Hey guys, I am working on my senior design project and I need to incorporate sensors that will detect dynamic objects like cars, walls, etc... within a reasonable range from a device (so we were thinking about using sonar sensor(s) for this)... we also need to somehow track the position of the device (possibly using a compass module and a velocity sensor because we kinda want to stay away from GPS)...
Any suggestions for particular modules would be much appreciated. Please email me at firstname.lastname@example.org.
I was looking at Devantech's Ultrasonic Ranger SRF08module only has a maximum range of 3 meters though.
I was also looking at Polaroid's Environmental Grade Sonar Ranging PackageSupposedly this module is capable of doing up to 35 feet but I wasn't able to find a range rating for the transducer itself. This transducer seems to have a somewhat spread range too which looked nice (our project has to kinda be able to detect objects over the frontal 180 degrees of the device).
I only started looking briefly but I wasn't able to find any velocity sensors that track the velocity of the device. Anyone have any ideas?
Thanks in advance,
