yes, the provided code speaks to the display module shown in the picture / video.

Hi, thank you for the circuit.

May I ask if your code is compatible with the display module in the fig.? Do I need to change anything?

please,,,How can I transmit data which were displayed on LCD from PIC 16F690 by Bluetooth transmitter to a mobile phone ???

please,,,if you can provide me with code and the pins connections between bluetooth transmitter and the PIC 16F690 , and which types of bluetooth transmitters do you prefer to use?,,, and what is the name of the program which I have to download to my mobile to receive data.

Thank you very much

Hey

Nice work,

could you tell me what distances could you measure the temperature over with MLX90614 ?

Hey there,

Thanks for sharing us the project. It is very cool. I’m on the same project too. However I could not a digital like the MLX90614 which would make my life much easier.
I wonder if there is a way that we could use analog detector like ztp135sr and using amplifier like the LT1126 to get the gain, the convert to digital with the TMEGA328 to create the it? would the code work the same with this combination?

How would u connect it thought? I’ve read couple articles but none would really show how to hook it up.

Thanks you very much.

Hi Sebastian,
You mentioned above a version of this circuit
where the o/p was into a PC via RS232.
I have right now a urgent need for such
a circuit, It will save me time and effort
if you could send me the code + diagram
for MLX90614-> RS232 O/P asap.
to…

Many thanks for your excellent work.
Kind Regards,
Mario Peiris.

hi friend

at first i am realy need to thank u very much…

realy i was study the contactless thermometer depending on infrared radiated from the bodies but my study was for another sensor and it was analog….
but now i decided to make the same project which u made here…
now i have a prpblem of getting the component … especialy the pic … i have visit the website u put for the pic but i don’t know the package of the pic . then also if u have a website that i can buy the LCD display from it plz send it to me.
thank u

Hi ibrahim.

Please check out the datasheet of the sensor. If I remember correctly, it will give you the average temperature of all objects which are currently in the field-of-view.

@admin thank u very much i am sory for asking u another question i t is about the distanco of the object in front of the sensor . so if it was far it will give a wrong tempreture . so what is the relation between the reading temp on the LCD and the distance and thank again

hi ibrahim,

The datasheet contains an example of how to convert the temperature to degrees celsius. It’s very easy, because the sensor provides the temperature already in Kelvin. See chapter 8.7.2 in the datasheet.

Hope this helps.
