DIY Smart Home Projects

The housing culture has been changing along to the smart home technology with development of IoT. Users are familiar with monitoring inside the house using webcam and controlling devices in the house remotely.

In addition, makers share their smart home projects on the Internet under the influence of open source hardware such as Arduino and Raspberry Pi.

This posting will show introduce the makers smart home projects.

Aquarium

Arduino Fish Tank Controller

This project shows how to implement web server using Arduino and Ethernet Shield for controlling the lighting device and feeding device used in aquariums. The author implements the device to monitor the temperature inside the aquarium and the outside temperature using temperature sensor.

Feeder

CatFeeder

The author developed this device to feed cats automatically.
There is a button attached to the device that can feed cats remotely. Users can also feed cats using smartphones because the Ethernet device is connected to the feeder.

Twitter Controlled Pet Feeder

This author implemented a device that can control pet feeder via Twitter Messages. Using the popular social network tool, Twitter, to control the pet feeder is the main feature of this project.

Garden

SmartGarden

This author built a system that can measure the temperature & humidity of the flowerpot and water them remotely. The cloud service called Paraimpu was used, enabling users to turn on and off the automatic watering system with a control signal from Twitter after sending the measured temperature value to Tweeter using Paraimpu.

CloudCooker

The author aimed to make a smart grill that can measure and control the temperature of the grill and food. This project can provide the function of controlling and printing out data in different forms at the Front-end using Azure cloud service created by Microsoft.

IoT Cloud Service

network-782707_960_720

There seems to be a lot of excitement about IoT these days. Gartner forecasts IoT devices would increase to 25 billion pieces in 2020 from 4.9 billion pieces in 2015. The industry will increase at least 5 times during the next 5 years. Although negative evaluation such as exaggerative advertisement of IoT exists, the fact is that the number of IoT device is sharply increasing at a fast phase. And if the number of IoT device increse, related service also increases. These related servicees will collect huge amounts of data and share the data with users after analysis. The capacity of server that handles IoT service should be in a state of flux depending on the amount of data collected if we consider the number of IoT device increased sharply. IoT service will also rapidly change since it is at an early stage. Then, the server program should be very flexible and IoT services require all levels of IT from “embedded” to “server”. Do you think this will require high technology? It does not. Cloud service meets all requirements; it can change capacity depending on the amount of data and its pricing and server programs are very flexible. Another advantage of cloud service is that users can drive its server by simply drawing a diagram instead of programming it.

So which companies lead the cloud service? Global companies provide cloud service such as Google cloud platform from Google, aws from Amazon, and azure from Microsoft. Besides that, there are endless companies providing cloud service.

This post will introduce a few of IoT cloud services from the WIZnet Museum.

1. IC2Cloud: www.ic2cloud.com

http://wiznetmuseum.com/portfolio-items/www-ic2cloud-com/

IC2Cloud is one of the easiest cloud service I experienced. The most powerful advantage of IC2Cloud is programming the server by using drag-amd-drop ICON such as App inventor. It is also specialized for IoT projects; there are 8 examples of Arduino uploaded on WIZnet Museum.

3. Dweet.io: Send data to dweet.io and freeboard.io

http://wiznetmuseum.com/portfolio-items/send-data-to-dweet-io/

This project used cloud platforms such as Dweet.io and Freeboard.io . It collects data through Dweet.io and shows the form that users want using Freeboard.io. Arduino and Ethernet Shield were used to implement this IoT device.

4. Cloud MQTT: How to implement embedded Mqtt Client using W5500 IC

http://wiznetmuseum.com/portfolio-items/how-to-implement-embedded-mqtt-client-using-w5500-ic/

This project  explained how to implement MQTT Client in W5500 custom board. For explanation, an exclusive cloud platform for MQTT called Cloud MQTT was introduced; it is made by using AWS cloud service and there is no need to implement MQTT Broker.

Even though the usage of clouds for IoT these days is already widely used, more IoT cloud platforms will become available because of its usefulness.

If you are planning a business that provides IoT service, I suggest you wisely choose the right cloud server, service, or platform for your application.

Online Data Analysis with Arduino and Plotly

plotly-arduino-data-graph

Project Description

The service, ‘plotly’ visualizes your data in graphs or charts. The author introduces how you can use this service by using Arduino board.

Introduction
It’s 2014 and the Internet-of-Things is flying along at a rapid rate with all sorts of services and devices that share data and allow control via the Internet. In the spirit of this we look a new service called plotly.
This is a “collaborative data analysis and graphing tool” which allows you to upload your own data to be analysed in many ways, and then graph the results using all sorts of plot types.
With plotly you can run your own mathematical functions over your data, run intense statistical analysis and use or edit one of the many APIs (Python, MATLAB, R, Julia, REST, Arduino, or Perl) to increase the level of customisation. Plotly works in conjunction with Google Drive to store your data, however this can be exported and imported without any issues. Futhermore plotly works best in Google Chrome.
For our review we’ll look at using plotly to quickly display and analyse data received from an Internet-connected Arduino – our EtherTen, or you can use almost any Arduino and Ethernet shield. The system isn’t completely documented however by revieiwng our example sketch and some experimenting with the interface plotly is very much usable, even in its current beta format.
