Arduino based Automatic Power Factor Control
(ilhami COLAK (Nisantasi University), 2021-09) Rakib, Md. Abdullah Al; Nazmi, Sumaiya; Md. Hasan, Imam
When the inductive load is brought into the industry, it is known that the power factor will drop. The electricity cost will be greater if the power factor is decreased. When power factor drops in our system, the automated capacitor bank is activated, and power factor is restored to a predetermined level. The unique element of our project is that an IoT (Internet of Things) technology was used to complete it. It will be able to monitor and operate the project from any place on the Internet, in addition to monitoring from the project display. As a programming device, it has been utilized an Arduino Uno Microcontroller. The PF may be improved to increase current-carrying capacity, enhance voltage to equipment, minimize power losses, and cut electric costs. Reactive current generators are PF correction capacitors. We contribute to increasing the power factor by helping to balance the nonworking power used by inductive loads. In this article, the power factor of a load is measured using an Arduino Uno microcontroller, which then triggers the appropriate capacitors to correct for reactive power and bring the power factor closer to unity.

- When the inductive load is brought into the industry, it is known that the power factor will drop. The electricity cost will be greater if the power factor is decreased. When the power factor drops in our system, the automated capacitor sets are activated, and the factor of power is restored with a predetermined level. The unique element of our research work is that an IoT (Internet of Things) technology was used to complete it. It will be capable to monitor and operate the research work from any place on the Internet, in addition to monitoring from the research work display. As a programming device, it has been utilized an Arduino Uno Microcontroller. The PF may be improved to increase current-carrying capacity, enhance voltage to equipment, minimize power losses, and cut electric costs. Reactive current generators are PF correction capacitors. We contribute to increasing the power factor by helping to balance the nonworking power used by inductive loads. In this article, the power factor of a load is measured using an Arduino Uno microcontroller, in which the necessary capacitors are then triggered to compensate for reactive power and put the factor of power closer near unity.

Design and Simulation-Based Parametric Studies of a Compact Ultra-Wide Band Antenna for Wireless Capsule Endoscopy System at Inside Body Environment
(International Journal of Electrical and Electronic Engineering & Telecommunications, 2020) Al Rakib, Md. Abdullah; Ahmad, Shamim; Faruqi, Tareq Mohammad; Haque, Mainul; Rukaia1, Sharifa Akter; Nazmi, Sumaiya
This paper focuses to design a compact (110mm³) Ultra-Wide Band (UWB) (3.1GHz to 10.6GHz) antenna, which covers almost the whole 10dB impedance matching bandwidth of the UWB range. Two of the main specialties of this article over other related articles are its antenna’s wider bandwidth (approx. 7.3GHz) and antenna’s simulation environment. No other papers consider such a realistic model to simulate their antenna, before. Due to its wider bandwidth, this antenna can be employed in the Wireless Capsule Endoscopy (WCE) system, which mainly requires a high-speed real-time data transfer-capable antenna. The antenna was examined inside simplified human Gastrointestinal (GI) tract phantoms (Colon, Esophagus, Small Intestine and Stomach) as well as the human Voxel GI tract model by maintaining proper tissue properties for the sake of accurate parametric results. Biocompatible material polyimide was used to construct the capsule wall to fulfill the system’s biocompatibility. In the result analysis part, the proposed antenna’s SAR (Specific Absorption Rate) or electromagnetic energy amount, consumed by near-side body tissue was considered and found in the acceptable region, according to Federal Communication Commission (FCC)’s regulation. Also, other crucial antenna parameters such as VSWR, reflection coefficient, radiation characteristics, efficiencies, directivity and surface current density were adoptable compare to other related articles. The Finite Integration Technique (FIT) of CST Microwave Studio Suite 2020 was used to investigate the antenna parameters.
