Now you may wonder if the device is connected to the network, and likely to even have access to the Internet, so why not just connect to the database directly and insert data straight into documents? This is a potential strategy, but you would have to make sure that your database connectivity library was small enough and resource restrained enough to run on things like micro-controllers and that its connections didnвЂ™t assume the underlying network was reliable. All this is done with minimal overheads and small libraries available on many platforms at the client end. Topics mean that a client may publish information with a topic вЂњdemo/devices/mydevicenameвЂќ and another client which has subscribed to messages for вЂњdemo/devices/+вЂќ will get the first client's messages, along with any other publishing client using a matching topic. Devices publish their messages through an MQTT client library up to a broker which then passes them on to any other client which has subscribed to them. These messages are simply composed of a topic and a payload its up to the system designer to decide how the payload is formatted, but MQTT can handle everything from ethernet packet sized data to megabytes. This is a protocol thatвЂ™s been created to allow devices to publish-and-subscribe to messages being broadcast over an TCP/IP network. From device to server with MQTTДЇirst though, lets talk about that protocol вЂ“ MQTT. The Arduino is a great platform for experimenting with electronics, sensors and the various ways you can connect devices to the Internet and have the added bonus of being a lot of fun to work with.

DonвЂ™t worry if you havenвЂ™t got one though, as weвЂ™ll show you how to simulate one in software later on.

And weвЂ™ll show you how you can put this together yourself.ДЇor this, we are going to start with a single thing in our Internet of Things вЂ“ a temperature sensor running on an Arduino micro-controller board. More specifically weвЂ™re using a standard protocol, MQTT, for moving the data from an Arduino-based temperature sensor to a message broker and then use just over 32 lines of JavaScript to move that data into MongoDB.

In this article, we're going to build a simple data acquisition device, use a common IoT protocol to efficiently get its data to a server, and then weвЂ™ll show how to plug into that server and turn the acquired data into a time series document in a MongoDB collection.

With the Internet of Things (IoT) poised to start pouring data into your organization, we thought it would be a good time to show you how you can bring that data into MongoDB so you can start analyzing it.
