Hi guys! I'm currently working on a project that requires an infrared temperature sensor with an accuracy of 0.1°C operating in a range between -5°C and 20°C. Actually, we didn't decide yet if we are going to proceed with this approach, but ideally, we want to use a non-contact sensor rather than a contact sensor.
If you guys know a sensor that fits these features or if you know where I can do my research to find one, I would appreciate your recommendations.
Depending on what you are planning to measure, IR sensors are partially dependent on the emissivity of the device being measured. Color, surface texture will both change the IR emissions and therefore the IR measurement. I've never used IR as a raw component but if you really require the 0.1°C ACCURACY (as opposed to resolution) you need to investigate the IR approach further.
Another challenge will be to verify the IR temperature is really accurate. You will need another sensor with greater accuracy than the 0.1°C
If you found it so easily, you can tell me which device has these features. I've only found devices with 0.5°C of accuracy at a specific range of temperatures.
The device to verify the accuracy of it doesn't need to be infrared, so that's not a problem. The real problem for me now is to find an accurate IR sensor. The most accurate I found is the MLX90614, which doesn't fit with my project.
Your information is very vague, it is like searching for a house that is red but not bothering to tell us you wanted red. I also do not understand why you are on the Arduino forum, you give us no information and want the world. I changed the search term from percent to C and guess what no problem finding them. I do not have the time or energy to go through all the different data sheets etc to find you something when I do not even know the "color"!
In searching for 0.1C the first hit got was mouser: [
