Homeowner Forum / Home Automation / July 2008Photosensor Search Help
Hello all, I have a customer that has a controller that uses a remote photosensor to determine if the sun it up or down. Simple enough but the photosensor has seen better days. Here is my problem. I need a source on just the sensor. I first thought that the RatShack would be a good possibility but nooooooooooooo. They have decided at the corporate level to now have candy bars on the shelf rather than electronic components. Gotta keep those shelves full of something. Boggles the mind???? Anyhow does anyone know of a source that will sell 1's or 2's of a component??????? I know that this is going to be tough since the shipping is going to just kill me. I could purchase a dusk-dawn sensor for a HPS 277v fixture and cannibalize it, but that may be taking this a bit over the edge. Any thoughts from the masses??? TIA Les Do you have the part #/specs for the photo sensor? There are many different types, with different resistances, and some that get more "resistive" when the light increases, and some that get less.. Fry's electronics might have a part that works, or some other "electronic parts" place in the yellow pages. Another option might be (if you know the manufacturer), you might be able to request a "sample". worst case would be someplace like Mouser or Newark, but the shipping could be more than the part. > Hello all, > [quoted text clipped - 22 lines] > > Les The biggest problem is the manufacture of unit that it is connected to is no more and there are no specs in the documentation. So I kinda have to wing it and hope I get lucky. FWIW the controller was made by Wadsworth Electronics and was call the SIMON Home and Building Controller. As I have figured out they have been out of business for a number of years. I think the resistance value goes high when it is dark and low when light. But at this point I will take anything just to see what happens. Thanks for the supplier names that will be a help. Newark is the one I just could not remember.

They are in stock http://www.radioshack.com/product/index.jsp?productId=2062590&cp=2032058.2032230 .2032269&parentPage=family Model: 276-1657 Catalog #: 276-1657 A call to the local RS store or 800-843-7422 (= 800-THE-SHACK) prominently displayed at www.radioshack.com might provide information on stores that still stock electronic parts and(or) how to obtain them by mail-order. I speculate that your local store can 'get it in' for you if you ask. HTH ...

Hmmm, try a combo of decaf and a phone call. ;) Did you look for the drawers of parts at the back of the Radio Shack store. Instead of taking up massive amounts of pegboard space for things that sell rarely, they have put them in cabinets which are actually easier to find things in. You have to face it, very few people know what to do with the small parts and Radio Shack would be out of business if they tried to make that the main part of the store. Digi-Key is a mail order place sells in small quantities. www.digikey.com/  SignatureBill Fuhrmann > Hello all, > [quoted text clipped - 22 lines] > > Les Yes that was the first place I looked.
