Parking a car is a real problem for many people. They can’t!
Unless there is a shop window to reflect off they simply have
no idea how to judge the distance between the back of their car and the front of
Ready to mount on the bumper bar or other suitable location, the Ultrasonic Parking Radar is simple to build, automatic in use and could save you $$$!
They either make life very hard for themselves, making what
should be a three-point parking a ten or twenty point saga (you think we’re
joking?) or, worse still, stop reversing when their tow bar has made a nice
little scallop in the number plate of the car behind.
Even a slight touch on a modern car can cost thousands of
dollars to repair, especially where integral, moul-ded (or non-existent) bumper
bars or too-sensitive air bag sensors are involved.
So what’s the answer?
Here it is – a small ultrasonic transmitter/receiver which
warns you when you’re getting too close. It’s designed to fit to the back bumper
(or other suitable location) of your car and sounds a buzzer or closes a relay
when you’re within the range you set – anything from about a metre down to just
a few centimetres.
While designed for the specific purpose of parking, there are
other applications where you might want to sense objects that come within range
– security is one which springs to mind, perhaps even things like vehicles or
other objects going past or through a small opening.
It’s all housed on one PC board (even the ultrasonic
transducers) which can all fit into a small disposals plastic case, ready for
mounting on the car.
