Saving sensor data to SD card using Arduino

- In this video I show you a simple Arduino-based project which consist of a LM335Z temperature sensor, a 16x2 LCD and a micro SD card reader. This project is a good starting point to learn how to write the output data of a sensor on a SD card. This is useful if you want to make a logging device that you want to put somewhere in a remote location or want to log data without having the Arduino connected to a computer. The possibilities are endless. You can add more sensors, format the data written on the card, change the logging interval, etc.

No matter how simple or "obvious" the structure of your program may be, for many beginner programmers it helps a lot to lay the foundations and logic that we can use in our programs. I greatly appreciate that you made this video because thanks to it I was able to finish my final project :)!
I am glad to hear that my video helped you with your project!
Amazing video, really helpful for begginer like me. I was figuring out how the sd card works. Now, I've got the insight about it. Thank you!
Thank you, I really appreciate your feedback, and I am glad that you understand now better how SD cards work!
Thank youuuu so much brother
I guess you read the description after your first comment.... :)
For arduino nano, which pins to connect to with the SD Card Adapter
I don't know by heart, but since it is an SPI device, just look up the SPI pins of the Nano.
Thanks for the video man, could you give me insight on how to introduce code it shows date of the data read. Cheers from Chile.
If you want date, you'll need an RTC module. Then you just read the RTC. I have a project on my channel where I introduced an RTC-based watering system. You can use that as a starting point.
Hi bro, good video! im just wondering, how if the data was stored in SD Card transfer to phone with bluetooth (maybe with ESP32). really appreciate if you make this one
Thanks!
Hey, I'm trying this with a load cell and amp. When I ran the code, everything looked like it was going smoothly, but nothing was recorded when I tried to look at it on the SD card, nothing was recorded and there wasn't a file to look at. How do you start and stop a recording?
Hi! Probably, you modified something in the code that hinders saving the data. Or you didn't format the card in the correct file system. It is hard to say anything without seeing the code.
@@CuriousScientist I was really confused because everything looked good and it was verified by the serial monitor. It turns out it was on a "boot" whatever that means. Thanks for the code and reply!
@@CuriousScientist however only records when the Arduino is plugged into the computer. Any thoughts?
That can not be right. I have a similar logger that runs standalone without the computer without any issues. Have you made any changes to the code? How do you try to power the Arduino?
@@CuriousScientist I've been trying to fix it, right now I'm using the port, but I've commented out all Serial communication, and it hasn't worked.
hi Sir, amazing video, what's name software on 14:45 . Thanks pro
Hi and thanks!
The software is called qtiPlot and I strongly recommend it.
hi sir when i executing this code iam getting that could not initialization SD card sir plz help me sir
Hi! I would guess that the code is looking for an SD card but there isn't any. Have you inserted the SD card? Is it formatted properly?
thanks, you just saved my rocket.
I am glad to help! Cheers!
@@CuriousScientist please provide the link for the code
@@Starman5771 watch the video and read the description maybe???
@@CuriousScientist Thank You for replying so immediately I was not expecting this🙏🙏
I hope that the provided resources will help you!
Hi man
Can you learn me how to save reading sensor fsr to sd pleas
Hi! Just watch the video carefully. Everything is explained thoroughly.
@@CuriousScientist thx but becaus iam iraqi (arabic) so i not understand way to save other sense
I cannot see how else I can explain this thing. I think it is relatively easy to follow my tutorials. I explain the code line by line and also you can download the code and experiment with it.
