DIY-Thermocam V2: A do-it-yourself thermal imager

I didn't see the webcam usb cables in the schematic. Does the webcam plug straight into the pc?

yes just plug on the computer.

I've been reading all your posts and all the forums and websites. I love this idea.. and i need something like this for a project im running. I'm currently running a system with hot water in planks, under hydroponic plants to see what response i get from the plant. I am looking for a thermal camera to take a couple pictures to see how much heat im radiating off. I was wondering if anyone has one for sale in USA or canada? for a fairly cheap price. I'm a student dont got much money but very interested in plant productions and hydroponics. and no i'm not trying to grow marijuana !! we are growing red peppers.

PM me!
THanks guys! awesome work too!!

If anyone can help me I would greatly appreciate it, I am having trouble getting the Java application to open. When I run the cmd prompt it returns the following

java.lang.UnsatisfiedLinkError: C:\Documents and Settings\Kenny\Desktop\JAVA\lib\win32-x86\rxtxSerial.dll: The specified procedure could not be found thrown while loading gnu.io.RXTXCommDriver

Any help would be greatly appreciated!!!! Thanks!

Hello,
Great project .
Can I get the source code of the arduino. i would like to make some experiments, and learn how the program works.

Hello

what is the usage of laser in the thermal camera.

Not quite sure about this... What OS are you using ? Have you installed the 32-bit version of java and uninstalled any 64 bit version ?

The laser is needed to match the sensors position with the optical image and to show you the current area measured

Great project!! Just finished building mine for a school project (research lab wouldn't loan me the FLIR camera). Max I noticed you removed the pull-up resistor note on your website - don't know if this was on purpose, but I connected the sensor directly to A4 & A5 and it's working without a problem.

I used the EEPROM update, it too worked without any problems. The surface temperatures I am getting seem accurate. This sketch is also a good way to be sure that you have the sensor connected properly - If it doesn't read the inital values, check your connections. Just unplug the 'duino before uploading the new values if you don't want them.

In reference to dvernor's question, I was having some trouble with the Java software too. I could get it to calibrate but when I started the scan, the program would hang. Uninstalling 64-bit Java and using 32-bit fixed it; working great now.

Other troubleshooting item - when I started the Java program for the first time, to calibrate, the arrow buttons didn't respond - I found that it was just out of range, if you press a button in the same direction for long enough the servos eventually respond...

Thank you for sharing all of your hard work on this!

Thanks for your feedback :slight_smile: Yes I removed the resistors in the schematic because I noticed they are not required to get the sensor to work. Unfortunately, the rxtx and civil lib do not work with 64 bit systems so a 32bit java is necessary at least.. The thing with servos is a bit confusing because the arduino sketch has standard values for the servos in it (in case you start the program first time) and those should be definitely in the servo's range. I hope this is a one time error and it works now for you :wink:

I have a question. Can I use a USB Port Webcam?

When i'm trying to run the software. it say's that "the arduino COM Port is not recognized." and my USB Port Webcam can be activated. But when i fixed the Arduino COM Port, my USB Port Webcam is not working. It says that "The Spectrum of your video camera is not recognized."

What should i do? i follow the schematic and the step-by-step procedure by building it.

Hi i have finally mount the cheap thermographic camera, but it's strange with the software i select quick thermal read.dosen't move, the clock dosen't goes down.
but with another code i found at internet.
the melexis seems to be working.

why it dosen't work with the thermal software?

Thanks

Jose

I wish to know how i must connect the servo

red wire 3.3v
black gnd
and white to digital d8 and d9

It's that ok?

Thanks

hi..i want to do this cheap thermocam project and i hav 3 doubts..

  1. do i just plug the webcam to the pc?? what if i hav a integrated webcam already??
    2.i hav 64 bit windows 7 and have installed both 32bit and 64bit java..how to run this java pc software??
    3.what i should do after assemblinf all my hardware??...i mean load configuration sketch ..then main sketch then what to do??
    sorry for asking such simple questions but i hav no idea abour Arduino before and im a begginer...lookin forward for ur help.. :slight_smile:

The website has been updated and version 2 is now finally there :slight_smile:

maxbot, fyi, trend 'worry free' anti virus blocks me going to your website, it's marked as malicious

Thanks for for reporting me that situation. Of course, my website does not contain any kind of malicious software. I have no idea how Trend Micro comes to their block..
I requested a reclassification on their website and hope they fix that soon.

I have not worked sensor ((tried everything that you can!
There is some way to test it on the performance?
My board Arduino Mega 2560
When I look through a serial port of the sensor is silent. White screen and all.

Try this code: http://cheap-thermocam.bplaced.net/MLX90614_new.zip
It is a re-implementation of the code with a new I2C library.
Take care that the Pins for I2C are different on the arduino mega. They are located on digital pin 20 (SDA) and 21 (SCL).

Thanks for the help but the sensor is still silent.



When I change the place of SDA and SCL I get a response
bient temperature: -273.16
Object temperature: -273.16
Ambient temperature: -273.16
Object temperature: -273.16
Ambient temperature: -273.16
I get the same thing when there is no sensor.
Maybe there is still what the realties ideas?
If you'd buy a new sensor. Just here in Ukraine they are at $ 120 )))

Thats shit. Sorry, but currently I have no idea what could be the reason :frowning:
From where did you order the sensor ? If it is not working, you should ask for a new one there.
However, I can order a MLX90614-DCI for you too. I get it for 30€ including taxes and shipping.
