WebIR radiation is basically a light that cannot be seen by the human eye. The IR LED detects and works at 980 nm (nanometer), that’s considered near to infra-red. As it is undetectable to human eye, it is perfect for wireless communication. IR radiations are everywhere, these emit from sun, light bulbs and many other things. WebDec 19, 2014 · The LEDs used by the Sparkfun tutorial are 1.6-1.8V x 10mA, meaning they are only really 18mW each, and there are 13 LEDs. That is 13 x 18mW = 234mW total of IR light. You are trying to do 25 LEDs at 1.6-1.8V x 100mA, meaning your IR light output will be a ridiculous 4.5 Watts. Do you really want x20 more IR light than the tutorial guy had?
