Abtsract: With increased involvement of technology in our interpersonal lives, home automation is a growing concept and a popular one. Nowadays, Internet is mixed with almost all our daily chores or at least that is the goal so why leave our homes behind? Our team has created an affordable and adaptable home automation system that is grounded by a smartphonecontrolled robot. The aim of this project is to use the Arduino board with a Bluetooth module to design a home automation system. The transmission of information between the smartphone and Arduino occurs via a wireless medium, with added security measures to prevent unauthorized access to the household appliances.By incorporating the latest technology, this home automation system provides convenience, security, and safety for households where time is limited. The main focus of this design is to allow the control of smart homes using smartphones, providing a security- focused solution for when residents are away. Our goal is to make home appliance control simple and user- friendly,with an econimic and simplistic engineering design using Bluetooth technology. This system can handle various devices automatically, including appliances like vacuums, light bulbs, and automatic doors.

“…Due to the advancements in IoT in the thermal regulation of buildings, many studies concentrate on implementing IoT in HVAC control. In Vosughi et al (2020), an occupant-centered control strategy, the Markov linear system, is developed in IoT enabled systems, only the model is not validated in real-time systems. Jeona et al (2018) discuss IoT-based occupancydetection in residential apartments based on changing patterns of dust concentration.…”

Occupancy-based strategies for the control of ventilation systems in buildings are effective for achieving energy savings and user comfort. Savings in energy consumption of more than 50% can be achieved by controlling heat, ventilation, and air conditioning (HVAC) systems with accurate sensory and occupancy information. In this study, the flow through the damper of the variable area valve (VAV) system and the speed of the blower’s variable frequency drive (VFD) are controlled in the HVAC system, on the basis of human occupancy and indoor parameters, namely, temperature and humidity, segment-wise in the building. In the proposed model, the flapper angle of the VAV is estimated using the indoor temperature, external temperature, and number of occupants. The occupancy data are fed to the controller proposed to regulate the flow through the ducts of the system, which is based on the flapper angle of the VAV, in order to maintain human comfort. The proposed scheme makes it possible to detect abnormalities in energy utilization and to trace maximum utilization in the building based on occupancy, with the control parameters of the HVAC adjusted for a comfortable indoor environment. Performance evaluation of the VAV system with its proposed control strategy, temperature, and flow distribution is simulated using Fluent software. A laboratory grade prototype incorporating the proposed control strategy is then developed, tested under three different conditions, and the results are reported. The experimental results show that an energy saving of 18% can be achieved.
