 The Great Search brought to you by Digikey and Ada Freer. Every single week, they use their power of engineering to help you get to find the things you want on digikey.com. Ada, what is the Great Search of the week this week? Okay. This week's Great Search is a part that did not survive the Great Ship Shorter 21-22. It's the TCS 347-25. So let's go to the computer and I'll show that we used to stock this part. This was our color sensor. I really, really like this sensor. So it's a six-pin chip. It required three volts, but it had an interrupt output and it had red, green, blue, and clear color sensing, IR cut, I squared C interface. It was fairly easy to use and it looked really cool. It had this very beautiful sensor with interleaved red, green, blue, and clear sensors. So we used it in a ton, ton, ton of projects. Pretty much anything that had color sensing, we used it. We made a flora version. But sadly, this chip did not, again, like I said, survive the Great Ship Shortage. It is discontinued. And I even was going to make a STEM IQT version. And it's like, just as I was designing it, the chip got discontinued, was no longer available. So sad. So here it is. It came in two families, the 34725 and 34727. Both are discontinued. And I really like having a color sensor. I think it's a great way for people to, you can detect what color a Lego block is or if you're doing like Rubik's Cube stuff or just pick up colors from around the world and like you integrate your project. We had an umbrella that you touched it to something and it would turn the umbrella that color that you touched. You could touch it to like a yellow cab here in New York and it would turn yellow or a red fire hydrant would turn red or green tree would turn green. Very cool project. We might actually remake that project again because it was so old and some of those parts are unavailable like this one. But I would like to have another color sensor. So let's check out what Digikey has for color sensors. So because I don't know at all what the land of color sensors looks like right now. I'm just going to click on the whole category. So there's only 84 parts. So remember everything including obsolete components you know are there. So what I'm going to do is first select only the active stuff and you see really not that many color sensors available which I think is interesting. I think there was like a trend to have color sensors for phones and TV so they could do like ambient color sensing and I think like whatever happened that got changed and like it doesn't get used as much anymore. So looking at some of these some of these are like they're a light sensor but only takes like one color like this only connects detects green. It's got like a green coating this one detects red is one text blue. So these are analog. They're just like a diode that's like tinted so it only senses that color. I'm assuming let's see. Let's actually look at the data sheet. Yeah, it's just Ano and Catholic. So it's just it's just a diode. I don't want that. I want something with I squared C you have you are too. But I you know I'd like something as close as possible to that TCS. Okay, we have a couple options here. Not a ton though. Like I said, you know 16 options. Some of these look like they're not even really stocked. So let's just say normally stocking and not marketplace because there's like a module or two I don't want. Okay, so 11 options. So some of these are like there's two kinds of light sensors because I've actually made breakouts for some of these. So like the as 7341 is very cool. You'll notice it's like whoa, it's like 10 bucks. Why is it 10 bucks? It's a multi spectral sensor. It actually has like nine different diodes not just red, green, blue. I want something that's a price comparative to the TCS and that was like a buck or two per piece. So I'd like to get something similar in pricing. So sorting by price. There's a couple good options. So one is the Vemmel 6040. So the Vemmel 6040 has a couple things going for it. It has red, green, blue and W just a clear like white light. But it doesn't have an interrupt pen which I don't like. I prefer to have an interrupt pen and there's no address select pin either. And that was one of the things that the TCS did have and was quite nice. You could change the address from like 0x29 to 0x39. I think it had one address select. So that's okay, but they're not amazing. Vemmel 3228 similar. Let's got clear red, green, blue and IR. So it's got, you know, a couple light elements in there. That's nice. But which I prefer that has at least four but it doesn't have again address select and it doesn't have interrupt output. So I looked around, there's this one which was kind of funky. So this one, this one looks pretty good. It has red, green, blue, clear and IR and interrupt and SEL. It doesn't have an address select but it does have interrupt which is kind of cool. It has the clear and IR ones on 3.3 Volts and it's from Everlight. I'll say I've had like fair good luck with Everlight and it's fairly inexpensive. That's under a dollar. And then this one, I looked at this one and I just saw the package and I was like, oh, I don't want to deal with that. Like that package looks way too small and complicated. It's like chip scale. The BH, so the AS72652 is another expensive one. It's like a spectral sensor. I don't need something this nice. And then there's just the AS7341. So one thing that I do like about the VAML3328 and the BH1749, which is another one, is that there's like a lot in stock and the price is fairly good. It's like again under $2. So this one, I ended up going with this one. You know, this is my pick, although I might change because it didn't have clear, but it did have IR. So that's kind of good. So you can do IR detection, ambient detection. And it had an address select. I really like an address select in the interrupt. That for me is kind of like key. And I think it makes it worth it that it doesn't have just a generic ambient clear light input because honestly, most people, you know, you might have a separate light sensor just for clear. And you know, maybe you can like sum the red, green and blue and that will get you like basically white light anyways. So this was my pick. Nothing was really exactly the same, but I really liked the stock numbers. The pricing was good. And I liked the interrupt pin and the address pin. And for me, since there wasn't ever something that had everything, this was the closest. So this is my pick for the great search. Let's go search. We're in the search with DJ King.
