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 :(
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.

They sent a new sensor. Works with the latest sketch. Maxbot, tell another how to change your code, that he worked for the board in Arduino 2560?

works flawlessy with this code, seems like wire is incompatible (well, the sensor seems to use a modified protocol)

Hi everyone!

I just found this project, and I was looking at the webpage, but I cannot find the software, is there any website where I can download the software?

Thanks in advance

Joc,
There's a version over here, but I can't get it running on a 64-bit mac. yet.
http://www.centralnexus.com/thermal/

let me know if you found another version somewhere.

I have built the camera....but when I use java software and hit START nothing happens ]:)
The countdown clock does not go down and scanning process as well.
I took all the codes from www.centralnexus.com
Any way to check functionality of my sensor as well?
Thanks guys!

Does anyone have a link or access to the original code that was provided the Cheap-Thermocam project? I have tried all of the related links and all of them are not valid links.

Thanks in advance for anyone help on this.

idea-thinker.

Hey ppl
I have basically built my 2d scanners and mounted my sensor, however i am having trouble getting the java program to interact with my arduino sketch. Any suggestions please. I just hooked up the scanner and started the motor movement, then pressed start on the java gui but there seems to be no communication even after i chose the  right comms port

Seyi

hi guys, please how do i get the java gui to communicate with my sketch. After i have chosen the right port, there still seems to be no communication

UPDATE: Version 3 of the Cheap-Thermocam is now available !
It does not use an arduino any more, instead I am relying on a Teensy 3.1 (ARM Cortex M3). But hopefully its still interesting for some people ;)

Unfortunately, for reasons of space and increased power requirements are no longer with an Arduino, but instead is a Teensy 3.1 are used. Hopefully the project is still for one or the other interesting smiley-wink


i would like to know what caused that hig requremnts.. seems like something get bloated

Some things have changed. I am using a 3.2 inch touch display, which would be hard to do with a standard arduino.
To reduce costs, I am utilizing a JPEG CMOS camera module and do real time conversion to BMP on the chip, in order to display it on the screen. Temperatures are running through a 2D gaussian filter algorithm to smooth the transitions, which is also very performance intensive. Flash space is also critical, fortunately the Teensy offers plenty of them (262kB).
