In this project I’m going to create a simple Datalogger with my Arduino and an Ethernet shield.

I’ll be using a photoresistor and a temperature sensor and all the information will be stored in a micro SD card.
The idea is that you can apply this to any sensor you desire!

Watch the Video below:

Step 1: Parts Required

  • 1x Arduino Uno
  • 1x Ethernet Shield
  • 1x Micro SD Card
  • 1x Temperature Sensor (I’m using the LM335Z)
  • 1x Photoresistor
  • 1x 1k ohm Resistor
  • 1x 4700 ohm Resistor
  • 1x Breadboard (or two)
  • Jumper Cables
<p>Hello. How many sensors can be connected to the Arduino Ethernet shield simultaneously? How many sensors can log data simultaneously on the SD card? Thank You.</p>
<p>Is there any Non volatile memory on the arduino itself that could be used for minimal storage? without the ehternet shield</p>
<p>Yes. There is a small amount of on-chip flash memory available on the Arduino. Be advised that there are limitations. Check out Arduino Playground - Memory tutorial. Best Wishes. </p>
<p>Since I'm using this for a science project, I'm just wondering what code language it's written in?</p>
<p>hi, i have question/need help with something... i am exactly at this same step on the arduino road... now i can read/write logs on the microsd, but... i was wondering on how can i append datetime to the log... i do not hace an RTC module, so i was thinking on some different way... apreciate your help and guidance....<br></p>
<p>I have one question:</p><p>I attach SD card on ethernet shield, and i tested it, and card read/write propertly, but i no view SD card on &quot;My computer&quot;, and i want to acess to file on &quot;My computer&quot;.</p><p>its on fat16 filesystem, everything its ok, but i can't see SD card on &quot;My computer&quot;</p><p>How to solve that?</p><p>Thanks,</p>
<p>Did you fix it?</p>
