IoT circuit board and application for smart home systems

A network of hardware, communication and electrical interfaces, defined as home automation, connects ordinary devices through wired connections or wireless devices using the Internet. Thanks to this automation, whether you are at home or thousands of kilometers away, you can control any device from your smartphone or tablet with sensors and internet connection. In this study, the application will be focused on the application of home appliance control over the wired and wireless system with the proposed model. The main idea behind the project design is to provide user flexibility, energy efficiency, ease of access and comfort. In the concept of smart home, which is defined as smart living spaces, these controls can be easily done by using Arduino and WiFi module to control the light, fan or any other electrical item in any room. In this thesis, circuit board design is planned for smart applications of smart home systems, the usage of which is increasing day by day. By programming the processor used in the designed circuit board, various controls were provided with relays such as water (on-off), electricity (on-off), gas (on-off). Light, temperature, fan, motors, inverters etc. Environment data were obtained by using sensors depending on modern techniques such as Wifi, and in the circuit designed using these data, control units for those techniques or communication with GSM module were provided. Proteus program was used to simulate the designed circuit board. Simulation tests of the designed circuit board were first performed with the Proteus program and after optimum results were obtained, the physical printed circuit board was created using the Ares program. Three-dimensional images of the printed circuit board created in the Ares drawing were created to provide a better understanding of the circuit board. The circuit was run on the simulation with the code written in C++ for the processor determined by the number of inputs and outputs. Arduino IoT Cloud Remote App has been created and commissioned to show the actual status of the device when the (ON/OFF) command is given to the device from the user wired module or telephone.
