Arduino data logger with two temperature sensors (LM35DZ) from my 3D printing material in car test

Title: Arduino data logger with two temperature sensors (LM35DZ) from my 3D printing material in car test. Watch on youtube: https://youtu.be/DPGnI0rhV2I

Tags: arduino, data logger, sdcard, temperature sensor,

Half years ago I had an experiment, what 3D printing material to use inside a car. In that video I used the results from Arduino temperature data logger, but only results were provided, and I promised, that whole Arduino project will be explained in a separate video (this one, with some delay).
So, in this video I will explain my Arduino data logger using data from two temperature sensors (LM35DZ), which are recorded on micro SD card. At the end, that data will be processed in Excel (or Google) table.

Hardware Required
Main elements:
- Temperature sensors: LM35DZ (2 pcs)
- MicroSD card adapter
- Formated micro sd card (FAT and not NTFS)
- Arduino Uno board
(I used Elegoo Arduino Uno)

Other:
- Breadboard
- Jumber wires
- Power Bank with 5V output
- Arduino IDE software on Windows computer
- Data processed in Google Spreadsheet
