[Tinyos-help] tinyos IR filter light by software

[Giovanni Rossi]

Hello
I can't insert another photo diode, in general I can't insert any types of hardware.
But I belive there is a method software I can mesure the IR light intensive, even if I has two light sensor
TSR(total solar radiation until IR) and PAR (photosynth-active radiation, without IR).
but I don't know how I can do. Anyone Know how to do??

thanks
