Use port 80 then enter the ESP-01’s IP address. Create a virtual server using the TCP protocol. Next, go to the Port Forwarding settings. After applying these, your router then reserves the 192.168.0.18 address to the ESP-01.Ĥ.

Also, enter the MAC address you got from the AT+CIFSR command. For our example server above, that would be “192.168.0.18”. Add the ESP-01’s IP Address to static so that it remains fixed.

Find out how to change the DHCP settings. For instance, my Hitron Technologies router uses “192.168.0.1”. Enter your router’s gateway IP address in your web browser. You can do this by searching Google for “what is my IP address”.Ģ.

Port forwarding is a network router feature that directs traffic from a particular port in your WAN to a device inside your LAN.

It should show this and should update every 5 seconds as indicated in this line from the code: client.println ("Refresh: 5").įinally, in order to make the server available outside your home network so that you can access it anywhere, we need to employ port forwarding.

Visit the static IP address (192.168.1.99) you set in the code in any web browser inside your network. Then using print(), we send the HTML commands to the client. In the loop function, we read the data from DHT sensor using readTemperature() and readHumidity(). Be sure to use an unused IP address or else you’ll encounter networking problems. If you want to use a different IP, just change the values from that variable. Next, we use IPAddress ip(192, 168, 1, 99) and EthernetServer server(80) to establish a web server at port 80 with a static IP address of “192.168.1.99”. If you’re not confident, check your shield for a sticker with your MAC address. So if you’re using the same as mine, leave them as is. The MAC address in the code is the default address for this type of shield. Next, we define the MAC address of the shield. Alternatively, you can go to Tools > Manage Libraries, and get the DHT library there. Additionally, we will use DHT.h to interface with the sensor.

Both are already available in the Arduino core library so no need to install. We will use SPI.h and Ethernet.h to communicate with the Ethernet shield.

If (character = '\n' & currentLineIsBlank)Ĭlient.println ("Content-Type: text/html") Ĭlient.print ("Arduino Ethernet Webserver ") Ĭlient.print ("Arduino Ethernet Shield Webserver ") įirst, we need to include the required libraries. Once you have connected all of the parts, upload this code to the Arduino: #include "DHT.h"ĮthernetClient client = server.available() The other end must be on your router that is connected to the internet. We teach Arduino programming and circuit building techniques that will prepare you to build any project.Īfter assembling the components, plug a LAN cable to the RJ45 connector. To learn more about the Arduino, check out our Ultimate Guide to the Arduino video course. To accomplish that, connect the following components, as shown in Figure 2: Building the Projectįor this project, we are going to display DHT22 temperature and humidity sensor data from an Arduino and an Ethernet shield paired to a web page you can access anywhere in the world. These are SPI pins, which the Arduino uses to communicate with the Ethernet shield. The pins you cannot use are pins 10 (SS), 11 (MOSI), 12 (MISO), and 13 (SCK). Simply line up the pins of the shield and Arduino and press them down until they’re in a comfortable fit. You can still interface with most of the Arduino’s pins using the female header pins of the Ethernet shield. The Arduino Ethernet shield has an integrated microSD card reader, which you can use to store files for your webpage. So if you’re looking for a wireless internet solution, you might want to look at an ESP8266 board instead. However, the shield only allows wired connection via the RJ45 connector. These chips have a network stack capable of both TCP and UDP. It is based on the Wiznet W5xxx line of Ethernet chips. The Arduino Ethernet shield is a circuit-printed board that allows an Arduino to connect to the internet. Unlike the Raspberry Pi, which is a fully-functioning computer, Arduino requires an Ethernet shield to connect to the internet. Just for the record, the Arduino alone cannot function as a web server.
