Abstract
The number of appliances at home is increasing continuously, mainly because they make our lives easier. Currently, technology is integrated in all objects of our daily life. TCP/IP let us monitor our home in real time and check ubiquitously if something is happening at home. Bearing in mind this idea, we have developed a low-cost system, which can be used in any type of electrical household appliance that takes information from the appliance and posts the information to the Twitter Social network. Several sensors placed in the household appliances gather the sensed data and send them wired or wirelessly, depending on the case, using small and cheap devices to a gateway located in the home. This gateway takes decisions, based on the received data, and sends notifications to Twitter. We have developed a software application that takes the values and decides when to issue an alarm to the registered users (Twitter friends of our smart home). The performance of our system has been measured taking into account the home network (using IEEE 802.3u and IEEE 802.11g) and the data publishing in Twitter. As a result, we have generated an original product and service for any electrical household appliance, regardless of the model and manufacturer, that helps home users improve their quality of life. The paper also shows that there is no system with the same innovative features like the ones presented in this paper.
Highlights
Domotics systems traditionally have allowed the adoption of Information and Communication technologies at home
It consists of a series of electrical household appliances that have connected a Local Sensor Host (LSH) which at the same time are connected to the Local Area Network (LAN) wired or wirelessly
In this paper we have presented a low-cost smart system that is able to gather data in a home network from electrical household appliances and posts on the Twitter Social Network the appropriate messages according to the parameters sensed from the electrical household appliances
Summary
Domotics systems traditionally have allowed the adoption of Information and Communication technologies at home. The increase of computational capacity and the inclusion of networking technologies in electrical household appliances are revolutionizing the way we interact with our homes. Fieldbus systems to Internet gateways are used to access data from the home They present an example that uses a web-server, which publishes energy measurements on kitchen devices. Like the ones presented in [5], use the existing home infrastructure based on open industry standards This system tries to integrate the home network with external networks to manage home devices, both locally and remotely. Some current solutions are being already sold in the market; an example is Samsung Snowing, RF4289 and Side by Side RSG309 models with capabilities such as time control of stored food for notice prior to its expiration date, or the ability to play music online [9] In all these systems a controller is responsible of requesting information from each appliance.
