Thank you for your question! The main objective of this project was to compare infrared sensors (IR) with contact sensors (IC), in terms of stability, quickness and usability for the user. In particular, we chose MCP9808 IC as it was small enough to be comfortable to be placed in a elastic band in the user's chest. However, any contact sensor will be suitable, the only need is to adjust the parameters, e.g. in the moving average, in order to properly tune the system for the pretended purpose.
Cool! Thanks for your answer! I'm trying to build a non-contact thermometer because of the COVID19, and I'm using the MLX90614-DCI IR sensor, and I notice the instability just by getting the raw measurements... I was trying some reverse engineering on some of those cheap non-contact IR thermometer, and I notice that those devices they get about 10 samples, and the "magic" happens inside the processor and I was wonder to know how to do that "magic". I tried doing some average samples and I notice that I would need to consider the external environment temperature as well... And after some research I find out your project and I'm amazed about the Kalman filter you applied to your project! Apply the same concept on my project, I notice more stability on my readings but I think I need to do some adjustments and I still learning about the "Kalman filter". So in my project I'm just using the IR sensor, do you have some advice to give to me how to make my reading more accurate and stable ? Was you able to make your IR sensor accurate and stable ? Btw: Your degree level is badass ! Congrats! Thank you for your time!
Hi there, great project you did there! I'm just wonder why did you use the MCP9808 IC sensor ?
Thank you!
