The Motion Detector Bricklet is equipped with a passive infrared (PIR) sensor. It can be used to extend Bricks to sense movement of people and animals. It has a configurable detection range of up to 12m with a sensing angle of 120°.
By using configurable events it is possible to react on detected motion without polling.
The fresnel lens has a blue backlight with controllable intensity. The backlight can be used as an indicator for detected motion or as a general purpose indication light.
Backlight in action:
|Current Consumption (LEDs off)||37mW|
|Sensing Range||up to 12m|
|Dimensions (W x D x H)||25 x 45 x 30mm (0.98 x 1.78 x 1.18")|
To test a Motion Detector Bricklet 2.0 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 Motion Detector Bricklet 2.0 to a Brick with a Bricklet Cable.
If you connect the Brick to the PC over USB, you should see a new tab named "Motion Detector Bricklet 2.0" in the Brick Viewer after a moment. Select this tab. If everything went as expected you can now see when a motion is detected.
After this test you can go on with writing your own application. See the Programming Interface section for the API of the Motion Detector Bricklet 2.0 and examples in different programming languages.
A laser-cut case for the Motion Detector Bricklet 2.0 is available.
The assembly is easiest if you follow the following steps:
Below you can see an exploded assembly drawing of the Motion Detector Bricklet 2.0 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.
