Data-logging with Arduino

[@SahaAditta]

Hello sir I have a question if I don't open the serial monitor then save the data in the sd card? I use a different power supply then the ket is working

[@Aghil-pw4bu]

ello... I want to create a table in Excel and save it in the sd card which contains three columns.. The first column is longitude and the second column is latitude and the third column is a number between 0 and 10... then We receive GPS input, and if the longitude and latitude were equal to each of the numbers we wrote in the first column and the second column, it will display one of the numbers (0 to 10) on the serial monitor... Your help is very important to me.

Great simple application for datalogging. You should see how many weather sensors I'm datalogging (hint i need a Mega) but one very basic and simple thing you can do is put a csv header in the void setup function that denotes variable type and units. Again this is more useful if your data string is long but good practice regardless.

Michael Padovani you are correct, thanks

Question: i want to datalog some much faster data (1MHz rate) with my due. Will the sd card be able to cope... 40% of available memory sounds like it is going to slow my programme down...

As I disect the code, I cant seem to find any information on the "File myFile;". "File" seems to be a function in the File class according to the Arduino IDE. But I cant find it anywhere in the Arduino libraries to learn more about it. I cant even find it in a Google search. Any info would be great! Also, thanks for the video, very nice!

Is the DHT22 an improved DHT11? Have you noticed any difference?

[@learnelectronics]

The DHT22 is supposed to be more precise, but I haven't noticed anything substantial.

Thank you for an excellent Chanel, its a fantastic resource. I mean no disrespect and I say this purely tongue in cheek, because I'm sure your aware of the irony of, Freedom units.

[@learnelectronics]

Im just joking. As an engineer, it was all metric system all the time. Base 10 just makes things easier.

Hello There! Great tutorial, I will use this for my University project. I have a question, what if I have more than 1 sensors? What do we change in the code? Thanks for the reply in advance. I know this an old video, but I still wanted to try my luck.

[@randomstudiosinc.8106]

Try askimg on stack flow

[@ikaranmali]

How can we add RTC module with this setup and sync time with temperature

[@homoevolutus]

sorry, how do you add more sensors? I have 4 sensors I have attached to log temps in a reptile incubator but what code should I repeat? thx!!

[@McKennaRobert]

It is saying my sd card isn't present when its inserted... any ideas?

[@mmulisha1022]

Can you data logg faster. I would like every half or 1/4 second. Obviously for a somewhat short time

[@vivekvenkatsubramaniam437]

How are you so prolific with your uploads? Great job! One question, though. Is data logging possible with a wifi module as well?

[@learnelectronics]

Vivek Venkat Subramaniam I have no social life lol. yes you can datalog over WiFi, you just need something (an application, or web server) to capture the data

[@Greenstonemovies]

It would be nice if you always put a link to the reviewed product, e.g. the sd shield in the description :)

[@learnelectronics]

It was in yesterday's video

[@Greenstonemovies]

Oh ok, thanks, i havent watched that one yet ;)

[@wilmersoemo]

Hi thank you for sharing this video!, may i enquire if it is also possible to do this with Analog signals?

[@ICStation2013]

Thanks for your wonderful project~~Grateful

[@learnelectronics]

Ics ICStation welcome

[@javierpallalorden]

Nice video, thanks!

[@fredlllll]

does icstation provide affiliate links? you could use those to get a little extra when someone buys a product with your link (at least banggood has these)

[@learnelectronics]

fredlllll no, they just send me stuff

[@fredlllll]

:O i also want to get stuff sent to me X3

[@javierpallalorden]

Could you please upload the code, thanks a bunch!

[@learnelectronics]

It's uploaded now, sorry about that. "Arduino Datalogging"

[@MuhammadAli-pe5ef]

schematic is not given

[@Thesportynerd16]

Great vid thanks man

[@learnelectronics]

+Jake DeBoer welcome

[@carlosthompsonlenz]

thank you for share, could you make more videos on the wemos boards d1 and mini, please. regards from cancun.

[@learnelectronics]

Carlos Alberto Thompson Lenz yes I will. thanks for the suggestion

[@AmericansByChoice]

Can you make a tutorial about graphing the data? Can you use the data logging to make a simple X.Y graphic to visualize the data? Thank you for all your videos.
