Chithunzi cha IR 3162PT850D-A3

Kodi pali kusiyana kotani pakati pa machitidwe a photodiodes ndi phototransistors?

1. Phototransistor ikhoza kuonedwa ngati mawonekedwe ophatikizika a photodiode ndi transistor. Makhalidwe ake ndi mawonekedwe a photodiode ndi mawonekedwe a transistor.
2. Ma Photodiodes atha kugwiritsidwa ntchito ngati magetsi kapena magwero apano (ie ma cell a photovoltaic) popanda mphamvu zowonjezera.
3. Phototransistor iyenera kugwiritsidwa ntchito ndi magetsi akunja, kotero kuti imatha kutulutsa zazikulu kwambiri zamakono kuposa photodiode, chifukwa yakulitsidwa ndi transistor.

- Kukula kwa 3 mm IR Kupyolera-bowo LED -

*Mlanduwu ukupezekanso ndi ma LED ena, monga: 5mm wobiriwira wobiriwira kudzera pabowo la LED, UV LED, 660nm LED, 940nm LED, 5mm buluu kudzera pabowo LED, LED yachikasu, amber LED ect *

- Kugwira ntchito kudzera pabowo IR LED -

* Mitundu yomwe ili pachithunzichi idatengedwa ndi kamera, chonde tengani mtundu weniweni wotulutsa ngati mulingo.

- Kupyolera mu dzenje IR LED Parameter -

- Kulumikizana kwa waya wagolide -

* Pofuna kusunga moyo wautali wa LED, fakitale ya BestLED imagwiritsa ntchito waya wagolide woyenga kwambiri polumikizana ndi dera.

- Kupaka kwa IR LED -

* Titha kulongedza LED iyi ndi mapaketi angapo ndikujambula kapena kupindika zikhomo za LED monga momwe mumafunira.

- Zogwirizana ndi infrared LED -

- Njira Yopangira -

- Kubowola kwa IR LED -
