The IR camera has an effective field of view is about 33 degrees horizontally and 23 degrees vertically (as measured on one unit). With the IR-pass filter intact, 940nm sources are detected with approximately twice the intensity of equivalent 850nm sources, but are not resolved as well at close distances. If the filter is removed, it can track any bright object. However, the IR filter referred to here is not only the dark plastic window of the wiimote but also a teensy slab of dichroic-coated glass inside the camera module. One may operate the wiimote having installed neither, one or the other, or both filters.
Ever want your robot to hunt down heat objects or navigated with fire? This is a small form factor IR camera capable of tracking up to four heat/IR sources. The applications are plenty and can go from tracking of robots with IR transmitters for navigation to light barriers, determining the direction where the object is going, and working as a flame sensor or tracking heat sources. Its fully compatible with Arduino with only four wires: two for power supply and two for I2C.
This infrared positioning camera can be controlled with Arduino, AVR via I2C interface. It is able to track mobile infrared points and to transmit the data back to host. The horizontal angle of camera is 33 degrees while the vertical angle is 23 degrees. It returns up to four points at a time when identifies an object. With advantages of high resolution, high sensitivity, high accuracy, small build and light weight, this Positioning IR Camera an be widely used in robot automatic search, robot soccer game, mobile trajectory recognition.
Whatsmore, this IR Camera can be used in making a low cost electronic whiteboard, touch screen and virtual reality headset, as seen in Johnny Lees TED presentation about cheap Wii remote hacks. For more details, you can check his blog.
Warning: Make sure the user knows about the power supply either directly on the sticker on the module or/and in the manual.
