Project Description:
********************
In today’s episode, you will learn how to make Temperature Logger using Arduino, MLX 90614 contactless Infrared Temperature Sensor, SD Card Module, and DS3231 RTC “Real time Clock”. For the data logging, I will be using Microsoft Excel.
For the implementation of this project, it is not necessary for you to use the temperature sensor, you can use any other sensor. And if you guys don't need the date and time, you can also drop the DS3231 Real Time Clock from your components list.
If you don't have this SD card module, you can just use a micro-SD card adapter. I have already made a video on this. I have also made a video on DS3231 Real Time Clock. So, you must watch my previous videos for learning the most basic things.
Now let me tell you what is my purpose of using real time clock with temperature sensor. You people know very well that due to the global warming, the temperature of the earth atmosphere has increased considerably, and this is not a good thing at all. I want to display the temperature as well as the date and time in the excel sheet, so that I can easily know what the temperature was on which date and time. This way I can compare my recorded data with next year's temperature values.
I have also selected MLX 90614 on some basis, because the temperature sensor is very fast as compared to other sensors. And another good thing about this temperature sensor is that, it’s a non-contact infrared temperature sensor. So MLX 90614 is a best choice for this temperature logger project.
After sharing with you some useful information, now I am going to explain its working, and then I will start practical demonstration. And afterwards, I will explain circuit diagram, Arduino programming, how to open the recorded data in an excel sheet, and then how to display the temperature data using graphs.
