Tracking Hot Spots

Monitoring infrared sources with the Mega88

Published in issue 383, November 2008

In this instalment, we add a miniature infrared camera with integrated image processing capability to the ATM18 system. This makes it possible to identify the positions of up to four infrared sources, display the positions on a monitor, and output their coordinates. Assembling a high-tech camera system of this sort is certainly affordable if you take advantage of mass-produced high-tech toys.
