DESIGNING AND PLANNING A SMART HOME PROJECT ANALYSIS What should I know before building a SmartHome? Planning is important step in installing sensors. - Gas sensors should be located near the floor for gases or vapors three or four times heavier than air. They should be installed near the ceiling or roof to detect lighter-than-air gases. - The best placement for a motion sensor is any corner that will detect human motion, as most of the motion sensors commonly used to automatically switch on/off the ights. Data cleaning process How should I clean the dirty data on Exlel? -Data cleaning involve different techniques based on the problem and the data type. Different methods can be applied with each has its own trade-offs. Overall, incorrect data is either removed, corrected, or imputed. -Duplicates are common problem when viewing a data file. Duplicates are data points that are repeated in your dataset. Excel provides function "Remove Dublicates" -Missing values, they can be calculated after filtering the data file. Ethical Concerns The greatest concern of Motion sensor tracking is the amount of information that can be deduced from the analysis of a person’s activity. Smart home data collected by someone or hacked, For example, who owns the information, who is allowed to access this information, who guarantees safety of data collected and ensure this being private. All these can be addressed as ethical concerns. Analisys and Conclusion First, I have analised the given tasks, what do I have to do? Create a poster, but I felt more comfortable to start from creating a Tinkercad design that is given in task objective looking at plan of the house, I felt it was very easy. All in all, I would advice you to start from easiest part of given task, or you will deep to one task untill you find a solution and spend more time than needed. For example, I could not figure out how it would be more comfortable to design a Tinkercad circuit and desided research Smart home based and used circuits all over the educational even constructional websites. Above we can see the diagram of Tinkercad circuit, which could be used in Smart Home that contains 4 motion sensors, temperature, light and gas sensors After finishing up my project, I am more experienced in creating any type of circuit in Tinkercad, and cleanin data files. I was not easy with focusing in tasks I have to accomplish in this project, as I think a poster should be focused on general topic that any reader could understand what is it about. Hence, I tried to include as much details as possible instead of pointing out which part refers to the particular task. WHAT IS A GAS SENSOR? Gas sensors (also known as gas detectors) are electronic devices that detect and identify different types of gasses. They are commonly used to detect toxic or explosive gasses and measure gas concentration. Gas sensors are employed in factories and manufacturing facilities to identify gas leaks, and to detect smoke and carbon monoxide in homes. The below circuit is a gas sensor with NeoPixel 12 ring, that changes colors from green, blue and red relying on gas. WHAT IS A MOTION SENSOR AND WHERE IS IT USED? A motion sensor (or motion detector) is an electronic device that is designed to detect and measure movement. Motion sensors are used primarily in home and business security systems, but they can also be found in phones, paper towel dispensers, game consoles, and virtual reality systems. Unlike many other types of sensors (which can be handheld and isolated), motion sensors are typically embedded systems with three major components: a sensor unit, an embedded computer, and hardware (or the mechanical component). A simple example of motion sensor with LED light that indicates if there was a motion. HOW SMART HOME SYSTEM WORKS? Conventionally, all smart home devices can be divided into several types: The controller is the “brain” of a smart home. This device controls the operation of the network and all devices included in it, stores complex scenarios (specific sets of actions) in its memory and provides a connection between the smart home system and your smartphone, tablet or computer. Various sensors that detect motion, smoke, leaks are the “senses” of a smart home. Thanks to them, the system continuously receives information about what is happening in the house. Executors - a group of devices that execute system commands based on data from sensors. For example, a ball valve instantly shuts off water if the sensor detects a leak. The relays turn the lights off and on, and the dimmers change the brightness. Control devices are devices for comfortable use of the smart home system. These are remote controls or, for example, batterypowered light switches that can be placed wherever you like. Other integrated equipment and web services - video cameras, equipment and services that have an open API (multimedia equipment, various modern technology, projectors, etc.) or controlled by IR(InfraRed) remote controls.
