IR compound eye
I have posted some tip/walkthroughs on home made IR sensors for obstacle detection and later for motion tracking. Now DAGU proudly presents the IR compound eye. Designed to fit LMR's universal sensor bracket, this sensor works by shinning IR light onto an object and then tracking the reflected IR. This sensor does not work in bright daylight as sunlight has a lot of IR and blinds the sensor.The IR LEDs can be controlled by a digital output so that ambiant light as well as reflected light can be measured. Your microcontroller needs 4 analog inputs available to use this sensor. See a video of it working here: http://www.youtube.com/watch?v=iKYCob7getU
Note: calibration is not normally required, heatshrink is provided fo those who wish to fine tune their eye. A black permanent marker can also be used. Incorrect application can reduce the range of the eye.
This product is now sold at Robot Shop.
