PARADA PRIETO, Elmer Alejandro et al. Low cost home automation system: a support to the ecological electricity generation in Colombia. Tecnura [online]. 2016, vol.20, n.49, pp.120-132. ISSN 0123-921X.  https://doi.org/10.14483/udistrital.jour.tecnura.2016.3.a08.

Context/Objective: In Colombia, consumption of residential electricity accounts for about 40% of the national demand; therefore, alternatives to reduce this consumption are needed. The goal of this study was to develop a home automation prototype to control the illumination of a household and to foster the efficient use of energy. Method: The system consists of independent control modules and an information manager module; the control module regulates the luminaires using a microcontroller and a presence sensor, and exchanges data by means of a radio frequency transceiver; the manager module allows the access to the control modules from a Web interface. The prototype was implemented in a household located in the city of San José de Cúcuta, Colombia, during a 60 days period. Results: The operation of the system diminished the total electricity consumption by 3,75 %, with a z-score of -1,93 that was obtained from the statistical analysis. Conclusions: We concluded that the prototype is inexpensive in comparison to similar technologies available in the national and international markets, and it reduces the waste of electrical energy due to the consumption habits of the residents in the case study.
