The Distance US Bricklet is discontinued and is no longer sold. The Distance US Bricklet 2.0 is still in development. For now, the Distance IR Bricklet and the Laser Range Finder Bricklet are possible replacements.
The Distance US Bricklet is equipped with an ultrasonic distance sensor and extends Bricks by the possibility to measure distances from 2cm to 400cm. The measured distance is reported as unitless value, not in mm. This is because the relation between the distance value and the actual distance depends on the exact value of the 5V supply voltage. Deviations in the supply voltage result in deviations in the measured distance values. With configurable events it is possible to react on changing distances without polling. Typical applications can be found in robotics, usage as light barrier alternative and so on.
|Distance||2cm - 400cm, 12bit resolution|
|Dimensions (W x D x H)||45 x 20 x 30mm (1.78 x 0.78 x 1.18")|
To test a Distance US Bricklet you need to have Brick Daemon and Brick Viewer installed. Brick Daemon acts as a proxy between the USB interface of the Bricks and the API bindings. Brick Viewer connects to Brick Daemon. It helps to figure out basic information about the connected Bricks and Bricklets and allows to test them.
Connect the Distance US Bricklet to a Brick with a Bricklet Cable.
If you connect the Brick to the PC over USB, you should see a new tab named "Distance US Bricklet" in the Brick Viewer after a moment. Select this tab. If everything went as expected you can now see the measured distance.
After this test you can go on with writing your own application. See the Programming Interface section for the API of the Distance US Bricklet and examples in different programming languages.
A laser-cut case for the Distance US Bricklet is available.
The assembly is easiest if you follow the following steps:
Below you can see an exploded assembly drawing of the Distance US Bricklet case:
Hint: There is a protective film on both sides of the plates, you have to remove it before assembly.
See Programming Interface for a detailed description.
