Over the Space Apps weekend we built a sample array of LED "pots" made up of a ring of 6 LEDS in a small cosmetics pot. The array is designed to be shown on a map where each pot corresponds to a grid reference. These arrays can then be connected to Infra Red cameras which show live images of the area on the map their pot corresponds to, so that the LEDs light up when a white or red colour is shown that corresponds to a fire.
We produced a sample program in Java that connects the LED array we built to a computer webcam to test how they respond to showing live images. The programming and production of the pots was a big challenge for us as we are a team of three A-Level students, so we had no prior experience in programming or electronics! However our array was a success and it responds very well to showing live images, and when the image shown is black, the lights switch off, meaning they wouldn't produce a false alarm due to the colours of the environment if used with IR images, as trees would show up as black.
