Figure 1: Network Connection Modules for Arduino.Ī simple solution for having an Arduino connected to a WiFi network, and thus to the Internet, is to use an ESP8266 module. However, such modules do not use the standard WiFi protocols, therefore you can't use them for directly connecting your Arduino to the Internet by simply using your WiFi router or repeater. Other custom solutions are also available, such as for example RF modules that communicate in the 315MHz-2.4GHz frequency range. It would also be nice to if we could watch what's going on at the monitored site even when we are not around, by going to a website that provides access to the (current and historical) sensor data.Īn Arduino can be connected to a network, and thus to the Internet, by using various networking modules, e.g., standard WiFi, wired Ethernet or Bluetooth, see Figure 1.

In case you are using the USB connector from your PC to power the Arduino board, be aware that short-circuits which may occur on the Arduino board may also have a negative impact on your PC!Ĭredits: some of the images from this tutorial are created by using Fritzing, a nice electronics modeling tool for beginners.ĭownload the Source Code for this project Arduino + ESP8266 = "I'm online, Mum!"Īfter we've managed to read data from the environment using sensors, we want to store the data for later use, such as statistical analysis or visualization. We cannot be held responsible for any caused damage! Do it at your own risk and/or ask help from an electronics engineer.

However, the low voltage may be obtained from a mains connected power brick, and therefore we highly recommend you to take safety precautions and to use a trustful brand for the power supply. For this project we'll use 5V, which is safe for the human body under any environment conditions. This tutorial is part of our learning materials on the Web of Things published on .ĭisclaimer: working with electricity is dangerous.

Part 2: Connecting to the Real World via Sensors.

You may first want tor read the previous parts of this tutorial series: As a newbie, it is helpful if you already have some familiarity with C/C++ programming and Web technologies, such as HTML and JavaScript. Using standard Web technologies, such as HTTP and Web Sockets, we can then access the data or provide commands to the WoT nodes.

In the following parts of this tutorial, which will appear every 1-3 weeks, we discuss how to control actuators and connect them all together in a Web of Things (WoT) app.

This third part shows how to set up a connection between an Arduino and the Internet via a WiFi network and use HTTP(S) to send data to a free cloud service like ThingSpeak. I mean I guess if you'd get a 3 port network switch with PoE support for every sensor, you could get away with running dedicated cables, but that would be very expensive.In this multi-part tutorial we show how to develop Arduino-based apps for the Web of Things (WoT).

You'll have to run one cable for each Arduino though. This PoE splitter for instance would allow allow you to easily extract 5V form the cable: IEEE 802.3af Micro USB Active PoE Splitter Power over Ethernet 48V to 5V 2.4A for tablet Dropcam or Raspberry Pi|Transmission & Cables| - AliExpressĪnd I guess this could be used to send and receive data: ENC28J60 Ethernet LAN Network Mini 51/AVR/ARM/PIC Code For Arduino SPI Port Module|mini mini|arduino minimini enc28j60 - AliExpress Or you could try to figure out a cheaper way.

PoE injectors that could take an input of 12V or 24V from your car are really cheap: POE Adapter cable RJ45 Injector Splitter Kit Tape Screened Passive Power Over Ethernet12 48v Synthesizer Separator Combiner|Transmission & Cables| - AliExpressĪnd then you could try to use a bunch of Arduinos with a shield supporting PoE like this one: Ethernet Shield W5100 R3 Support PoE For Arduino for UNO Mega 2560 Nano Free Shipping|ethernet shield|poe poepoe ethernet - AliExpress Maybe it would be a good idea to simply use PoE. I think instead of soldering to the wires directly I'd just buy a rj45 jack and solder to that: 10Pcs/set RJ45 Network Ethernet 8P 8C Female Socket Connectors 8Pin PCB Mount RJ45 8P8C Single Network Port|connector 8pin|mount connectorconnector rj45 - AliExpress I think that's why PoE operates at around 48V. Take into consideration that you may have to deal with massive voltage drops.
