0:00 Hello~~ Today I will teach you how to measure temperature using a thermocouple and MAX6675.
0:29 In this video, I will not discuss the working principle of thermocouple or the cold junction compensation circuit.
0:35 I will make a separate video about it
0:50 I bought a MAX6675 module with a K_type thermocouple included as an accessory and a built-in MAX6675 chip.
1:02 The MCU will use ESP32, and since many open sources and libraries already exist, it can be driven without difficulty.
1:13 One of the main points today is to examine whether it works correctly even when using an industrial K_type thermocouple (JIS standard).
2:12 Now let's take a quick look at the program.
2:19 First, open the library manager by clicking the tool tab and the library management tab sequentially.
2:25 Search for MAX6675 and SSD1306 in the library search box and install the library.
2:34 Click "Install" to complete the library installation.
2:47 I have already installed.
2:53 I'll open an example called "serialthermocouple" from the library and modify it a bit.
3:41 Compile and upload the modified code.
4:28 Confirmed that it works without any problems.
4:40 Edit your code to be concise.
4:56 This time, I will change only the thermocouple and test it.
6:19 Let's compare the performance with other thermometers.
7:02 There is a difference of about 0.5 to 1 degree, but it has not been calibrated, so you only need to check whether it works.
7:34 Lastly, I will increase the length of the sensor and mount a display so that it can be used in practice.
8:01 Let's copy a few lines of code from the SSD1306 OLED library.
10:11 So far, it has been a video of making a thermometer using a thermocouple and a cold junction compensation converter chip.
