I am thinking of building an ultrasonic distance measuring device for
an electronics project. Stanley has one on the market for about $30. It
is the size of a pack of cigarettes and has a max. range of around 32 feet.
They have a model with a max range closer to 50 feet for $50-$60.
A few questions come to mind when thinking about building one of these.
I am assuming these work in the ultrasonic range. Is this correct?
Can the transmitter also be used to receive the reflected signal?
Are there any chips available that would greatly simplify the construction?
Thank you,
Steve
