hi, i'm doing a little experience with infrared emission,reception modulation etc
eventough my system(very primitive) works fine indoor it is not the same outdoor,it looks that the sfh250 Ir receiving diode when exposed to the weak winter sun of northern Italy is able to generate about
-400 mV on a 1MOhm load
What is it due to? and how can i avoid it if possible?Shielding?Red glass filtering or what ??Thank you
