Arduino – Datalogger with Temperature Sensor and Photoresistor

Picture of Arduino – Datalogger with Temperature Sensor and Photoresistor
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

Picture of 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

Step 2: Schematics

I have one question:

I attach SD card on ethernet shield, and i tested it, and card read/write propertly, but i no view SD card on "My computer", and i want to acess to file on "My computer".

its on fat16 filesystem, everything its ok, but i can't see SD card on "My computer"

How to solve that?

Thanks,
