Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

This post is a review of some commonly available distance measuring sensors in general and the Sharp GP2Y0A21YK0F in particular. ... The most commonly used distance measuring sensors are: Ultrasonic ...

Everything always looks good on paper (and in its seller’s description), so I plugged my module into an Arduino Prototyping Shield for a quick/lazy evaluation using an Arduino Uno. If you have played ...

This ultrasonic radar project is from [mircemk] who uses a small ultrasonic distance sensor attached to a rotating platform. A motor rotates it around a 180-degree field-of-view and an Arduino ...

And ultrasonic sensors have been used in distance-measuring applications. Other common uses today include: Object detection and ranging in automated robots (e.g., self-guiding vacuum cleaner) ...

1. Ultrasonic sensing works like radar. A radiated signal is echoed back, and the time of transit is measured. The distance is then computed based on the speed of sound in air.

The non-contact ultrasonic sensing principle minimises any wear and tear issues to ensure reliable operation at temperatures ranging from -25º to 70ºC. This easily integrated sensor provides reliable ...
