SparkFun FLiR Lepton Camera Module

[@jacobwcrosby]

It's not detecting the temperature of the glasses, it is measuring the emissivity, which is minimal, thus they appear black (cold). This is how thermal imaging works, also the reason that certain things, coatings, objects, etc. etc. appear much, much colder than they actually are. It's also the reason that you have to tinker with the emissivity settings of most IR thermal sensors in order to accurately measure an object.

[@matt.squarebody5427]

thats pretty much what he said

[@jacobwcrosby]

+Nexus Customs Not really, he specifically said that it is detecting the surface temperature of the glasses, but if that were so they would appear much, much hotter, i.e. Everything else in the room...

[@ronin6158]

yes, classic misunderstand of 'heat'-- internal thermal (kinetic) energy and the transference of via conduction, convection and radiation. In this case, regular glass does have a very high emissivity, though a very low absorbtivity, so it doesnt soak in much heat from his face, and sheds what it does quickly.

I love SparkFun, every time i came for an electric part i am amazed about he new arrivals you have in your shop, thank you.

[@SouthernOregonCoast]

80 × 60 pixels may be more than you need, don't get hung up on inherent resolution! Tim Minerd and I prototyped perhaps the first CCD based document scanner in the early 70's while working at Xerox. It was based upon a 1x256 linerar CCD element. From that experience and watching slow scan television pictures of the early space flights reminds me that the inherent "resolution" is not as important as the sensor sensitivity and spectral response. I can see how putting this sensor on a servo or stepper, is capable of giving you all the resolution you need for a stationary application such as scanning attics for heat loss or intruder detection. If you really need "real time" high resolution . . . that is a different story. Looking forward to playing with the Lepton FLiR mounted drone scanners for a post fire incident aerial mapping project. Anyone else interested?

[@20_deshpande_aditya_vinay5]

I am interested

[@Michael_Miro]

how long is the range of this camera module?

[@julhiocesarnavas1733]

Hello ! How much fps (or Hz) is the lepton sensor of the video ? Is this the radiometric version? Thanks

[@QAYWSXEDCCXYDSAEWQ]

Is there a more upto date version of this?

[@ingmarm8858]

Ah the great misconception about "grounding yourself" to a metal object.... sigh. Was 7 years ago so hopefully you've learnt about ESD since then :-)

[@UnTamedMustang]

Can i resolder this onto an 8833 ?

[@bobiggins8027]

Is there a cost effective way to focus the incoming IR, for seeing farther away?

[@mrkiky]

you could buy some znse lenses off ebay and figure out something with them. it will cost you 20-50 bucks a pop. probably no cheaper way.

[@Tadesan]

Also, the pixel size will be a hard limit.

[@Souvi29]

Hello is it possible to desactivate the color mapping?

[@johnsontimmysamuel8012]

Could you please help me with this qmake&&make warning Target is empty Make nothing to be done first

[@johnowens4240]

This was published 3 years ago, but I still get the red box and removing the module and reinserting it does not work. Where is the new code promised?

[@zaighummir145]

i am having the same error !! Can u help me if u had find the solution

[@saadamiens]

why is the resolution so low and price so high !!!

[@n.karamousadakis]

saadamiens Well this stuff is pretty expensive, except the one FLIR made for iphone5 that's like 250 bucks

[@juliancolorado9232]

hi how i can buy this camera, i am colombia

[@thefatmoop]

This thermal sensor doesn't come with the calibration micro shutter that's included with the TG165's lepton. 350$ uncalibrated is awfully steep when the handheld FLIR TG165 visual thermometer is 100$ more (same sensor). That and you have to pull this 'static sensitive' module out of the socket occasionally? Sparkfun come on! what are with the prices? Are you becoming radio shack? Not to be too harsh, you guys are awesome! If your prices (not just this module) become more reasonable, you'll get some of my business again.

[@glennedward2201]

thefatmoop ,Agreed and I don’t buy from spark fun they overcharge for product. If I ever needed something I couldn’t find elsewhere I may consider but I’d definitely look around first. A lot of these sellers raise their prices as they build recognition and web traffic. The sensor is way overpriced given Intel’s D435 is only $89.

[@yorganyog]

Can't find those on google, wanna read more about those cameras.

[@glennedward2201]

Yorgan Yog, if you’re asking about the Realsense you can buy them at wholesale price here: click.intel.com/realsense.html The Realsense also has a sdk web dev site anyone can join and forum you can partake in. There are currently around 15-20 software programs already developed for it and many you can either download free, or at a reasonable price if you want a program developed by a particular resaler. Givin stereopticon camera’s with flir sensors already installed that will most certainly out perform in an application over using the above for a dev project that may never work correctly. Correction to above comment the older Sr300 is $89 and new D400 series are $149 and still a bargain. We have 3 Intel sensors here, 2 D435’s with Aaeon Up board and a D415 with its own Arron Up board. Beyond two sensors used at a time you need to use a Nuc or a PC.

[@danielc.4989]

So... Does the camera itself adjust the colormap or could I write code to allow me to do it manually?

[@lazybeastz182]

yes you can write your own code the camera just outputs numeric data

[@soulife8383]

WOW, it costs more than the FLIR One and the Seek micro usb adaptors.. And the Flir One has a built in battery, 2 cameras, better quality imaging, etc.. I get that this module is more flexible, since it can be added to any project and you can write your own code for it, but the Flir One has so much more and better hardware for a cheaper price, so it feels like someone is getting ripped off at that price, either sparkfun by the manufacturer or us by sparkfun. holy crap. I thought i could build a flir one for cheap but i was wrong if i use this module lol.

[@juancarloscardenasviera780]

Hello, nice video. Do we have the correction on the code? to the error of the red screen?

[@zaighummir145]

hi i am having the same error.Can u help me out?

[@legendaryurbangardening1930]

@@zaighummir145 @Juan Carlos Cárdenas Viera I am having the same issue with no success. Is there a possibility either of you have been able to get past this issue?

[@OriginalXfyre]

version 3.5 is out... at $259 for the Thermal image module, and another $100 for the Smart IO board that lets you plug in via USB straight to your computer

[@legendaryurbangardening1930]

Hi there, I am currently trying to get the 3.5 to work on my raspberry Pi. I am getting the issue that he mentions at the end where I get the red box but am unable to fix it. do you by any chance have any reccomendations?

[@mariuszwilk4718]

what is the frame rate?

[@jtauscher]

something like 9fps...best sensors have 30fps afaik

[@mrkiky]

A bit off on the theoretical explanation in the beginning. It's not "real heat" it's EM radiation that hot object happen to emit on their own. The radiation itself is not heat.

[@tridan95]

It's a kind of heat transmission called thermal radiation, so, it's actually the "heat" of the object

[@mrkiky]

Trí Dân Nguyễn Thermal radiation is nothing but radiation emitted as a result of having a temperature. It is not the same thing as heat, which is a form of energy stored in the body itself.

[@isbestlizard]

WOW i want to put one on a drone :D

[@ronin6158]

ps: its still a photon. 0:27

[@SoCalFreelance]

I wonder how much it costs to manufacture, probably $5.00

[@Hoverbot1TV]

Ya but the assembler is probably 120million. This is why China has not mass produced TAU camera clones. It is way out there manufacture.

[@SoCalFreelance]

Hoverbot1TV I only say this because the iPhone 6 camera costs Apple $16.50 each and it's far more complex than this camera.

[@Spirit532]

+SoCalFreelance It's less complex to manufacture. With any luck you can make your own visible light sensor at home with very crude techniques. Making a microbolometer under vacuum? Good luck.

[@_google_user_]

This should be like 60 bucks what a rip

[@jonhdoe1395]

You're free to source those and sell them for 60$. I'll buy two if you do it.

[@_google_user_]

Im just ssying

[@mrkiky]

it is a bit disappointing that the seek thermals and flir ones have higher res sensors and they are completely integrated attachable modules and come at about the same price. I would like to buy one of these just to mess with it if it was cheaper.

[@glennedward2201]

I agree it’s overpriced especially given the few$$ to manufacture those. Intel Realsense has an 80x60 which is similar specs as this yet comes as a complete ready to go Scänner for $149 (D415/435). The SR300’s are around $89 though I don’t recall if that model uses flir or not. Anyways buying a completed unit makes sense even if thermal imaging is all you’re after.

[@glennedward2201]

Also check this out! If you want to buy a high end 20mp FLIR complete they’re $599 which is quite the value considering what you actually get for resolution and a completely assembled product. www.testequipmentdepot.com/flir/aerial-drones/gimbal-cameras/zenmuse-x4s-gimbal-camera-4211869.htm?ref=gbase&gclid=EAIaIQobChMIi8-zlbe93gIVWrjACh3YIQDdEAQYAiABEgLqmvD_BwE

[@durandalgmx7633]

Before you get excited, its "cheap" at $240

[@t4fast]

expensive :(

[@LawrenceBrennan]

Cool!

[@Robots-and-androids]

Ouch $350! Does this guy have ants in his pants or is he just a dancer moonlighting as a product reviewer?

[@soulife8383]

That's what I said! it's still a little over $250 3 years later, and $250+ is still an Ouch.. Especially when considering that the Flir One micro usb adaptor is cheaper and comes with better hardware.. I bet the Seek micro adaptor is using something like this and even that is "only" $175~ish

[@chococatreeves]

Be careful with the concept of heat. With "that means real heat" the commentator implies only IR radiation involves heat, or represents hot things, or can heat things. You can heat things with any radiation, and you can raise matter to temperatures to spontaneously emit visible or UV light, for example. It's just that matter at normal terrestrial temperatures spontaneously emits more IR than anything else. If the module didn't have a visible-blocking lens, visible light would warm the micro-bolometers-just the same as visible light from the sun, filtered by the glass of a window, warms our feline heat storage units. If you were concerned with heating and cooling of objects at around 2000°C-5000°C, you'd want a glass lens that allowed mostly visible light, but the bolometer-part would be the same.

[@TheAstronomyDude]

super expensive at $350 though

[@torfaydo5007]

TheAstronomyDude actually it is considered cheaper if you compared with the price of FLIR camera out there that cost about $1000 and above for a much higher resolution. But for students to buy this module for their project you can say it is still expensive.

[@leppie]

I was going to comment, but Google makes it too fuckin hard to reply...

[@lazybeastz182]

wow this is even cooler than a poo poo head!

[@built2last31]

how is 349.00 cheap wtf u can get better modules for way cheaper than this!

[@RGplayer101]

yeah it looks like a really bad typo. can't imagine it to be this expensive

[@NerdNordic]

RGplayer101 It is. This technology is new and expensive as fudge..

[@JohnProffer]

NerdNordic its not new.

[@NerdNordic]

John Proffer Well, these sensors weren't intended for the consumer market until now.. Professional equipment usually isn't cheap and this consumer microbolometer thing is new = expensive.

[@bobiggins8027]

Is there a cheaper option? please share. From my understanding this tech is still under development, we just don't have a "cheap" way to make it yet, you should be hella excited at that price point. It's down now to $250 as well now.

[@EquinoxTheGryph]

"cheap"

[@bryangarcia4153]

You don't have to say "long wave IR sensor". If you have taken any basic science class you would know that you are being redundant.
