### Overview

This project shows you how to measure Temperature and Humidity and record data on an SD-Card with an Arduino Uno and an Ethernet Shield. The first step is to assemble your Arduino Uno and the Ethernet Shield and build the following circuit with your components as shown below. And insert a SD-card on the Ethernet shield. ![](https://wiznetmuseum.com/wp/wp-content/uploads/2016/12/v6LCqEYvXJiduMGRc2Sr.jpg) You can now upload the code on Arduino and the sensor will start measuring the temperature and humidity.
