Abstract
The advancements in technology in the world tend to make life for humans better. As time progresses, new technologies as well as improvement of existing technologies consistently given birth to a better, comfortable, safe and more secured way of living. One of these technologies which fosters better living in recent times is the smart home technology. This enables house owners to interact with their home. It brings about stress-free and risk-free means of controlling household system. This paper presents the utilisation of cheap and open-source materials in the development of a Short Messaging Service (SMS-based) smart home system. These materials include the Arduino microcontroller, SIM800l GSM module, electric relay, and some basic electronic components. Object-oriented system analysis and design (OOAD) was adopted as the development methodology for the research. Upon testing, the system was able to receive commands via SMS in order to turn on and off of Alternating Current (AC) appliances at home. Also, the system sends acknowledgement message to the sender to confirm if the command was carried out or not. It could check if the command it received was sent from the house owner’s phone or not. If command was from the house owner’s phone, the command is honored but if not, it is discarded. This is a feature that enables the home appliances not to be controlled by unauthorized persons.
Highlights
The world’s advancement being accompanied by the evolution of technology has always tend to make life easier for people in their home, offices shops, even on the road as well as in their cars
Having considered how speed of execution of commands as well as security of the system is important the system, these factors constituted the key parameter indices (KPIs) upon which the developed prototype system was tested. Speed in this context referred to the responsiveness of the Alternating Current (AC) appliances in executing commands received from the user mobile device, while security referred to the sensitivity of the system to intrusion into the home
For the purpose of testing, it is important to note that three AC devices were tested thrice, and results obtained presented in Table 1, and analyzed graphically in Fig. 8 below
Summary
The world’s advancement being accompanied by the evolution of technology has always tend to make life easier for people in their home, offices shops, even on the road as well as in their cars. One of the technologies which the evolution of technology in this advancing world has brought is the smart ability of operation of gadgets, which a major is the smart operation of household appliances. The smart home technology attempts to make the home as safe as possible as well easy to operate electrical appliances in the home [1],[2]. The intention of making the home a risk-free environment with an easier method of control for all ages is what gave birth to the smart home technology. The manual dummy operations of home appliances have been faced with a major risk of electrocution which has cost the lives of several and has left many injured. The partial to total exposure to high voltage AC has in several cases led to death, in other to remedy this issue the SMS control of home appliances which isolates the user or operator from getting close to the AC voltage is proposed
