where can i get specs of ldr with 4mm and 10mm sizes? maybe later i can add pictures of the LDR

can you also suggest circuit digrams with led, ldr, resistor, etc.

yhandz... bili kna lang nang 4mm and 10mm na ldr. but for most application ok na ok na yung maliit or yung 4mm na LDR.

i test mo sa multimeter mo yung resistance kasi walang specs yan minsan eh kahit part number. i experiment mo na lang like...

dark room = 1mohm
desk lamp = 500 kohm
ambient room = 400kohm
direct sunlight = 100kohm

that way may calibration kna nang LDR mo.
http://en.wikipedia.org/wiki/Photoresistor would help too.

madaming ciruit sa internet na may LDR light application isa na yung dark operated night light or simple Light meter.

light meter na lang para madali. kabit mo lang sa multimeter ayus na!

yun nga eh wlang alam na part #.. kahit anung part # ata daw pwede tapos i.compare q na lng sa ldr na binili q... saan site ba makakakita ng part # ng ldr?

mas maganda ata kung photodiode na lang gamitin mo kasi may part number than LDR's

or go farnell

OT: kamusta po yhandz?!

SILONEX - NSL 4962... eto ata medyo pareha sa ldr... d pa tlga aq sure mas madami kasi yung curve lines sa ldr kaysa yung nasa pic pero yung styles ng curves nya pareho tlga and yung try q yung ldr q eh yung sa dark room is 1.45Mohms den yung nasa specs naman nya minimum sa dark room is 1Mohm... malamang pwede na nga ito...

iinterface mo ba sa mathlab?

bluegirl · « **Reply #9 on:** November 27, 2009, 11:18:49 PM »

hndi po... d pa aq maxado marunong sa matlab.. sa livewire cguro... yung livewire po para xa multisim.. yun lng yung na download ng free eh

pakihanap po ng specs sa ldr na ito.... may nahanap aq na silonex pero d aq sure

insomartin · « **Reply #11 on:** November 28, 2009, 09:31:07 PM »

yandz, para saan yung specs sis?

insomartin · « **Reply #12 on:** November 28, 2009, 09:34:42 PM »

i mean kailangan mo ba talaga nang datasheet?

oo.. need q datasheet.. nakita q na datasheet na iyan.... ewan q yung 500 series medyo pareha sa ldr q kaso may cap.. may nakita aq sa farnell... nsl 4962 medyo pareha din xa... yun cguro nsl yung ipa.pass q

actually bumili ako nang dalawa kanina sa e-gizmo nung 5mm na ldr and makaki ang difference sa tolerance. parang 200kohm yung difference sa isa't isa. kaya i think ok naman na yan.

bluegirl · « **Reply #16 on:** November 28, 2009, 11:53:51 PM »

10 mm kasi yung ginamit q kaso konti lng specs sa 10.. mostly sa 5 mm madaming specs

LDR 10mm

anu po ang part # ng ldr na iyan?
