Come realizzare un sensore IR di oggetti ESPERIMENTANDA

La radiazione IR emessa dal trasmettitore infrarosso costituito da un comune led viene riflessa dall’oggetto, dopodiché viene immediatamente catturata dal ricevitore (il fotodiodo IR) e di conseguenza viene prodotta una tensione. Ecco come viene rilevato un oggetto. Come in tutti i normali LED, e nel fotodiodo, la gamba più lunga è l’anodo (+) e quella più corta è il catodo (). Segui ...
