Development of a Smart Motion Detection Device for Home and Office Security Applications
The aim of this paper is to develop, implement and test an effective and practical working solution to a smart motion detector for LPWAN technologies using appropriate software and hardware platform. The smart motion detection system consists of a Raspberry Pi, an LCD display, PIR sensors, and wires. The hardware design collaborates with Python programming by being installed on a Raspberry Pi, and it is a key function to detect who is entering a room. The proposed smart motion detector wi...
Smart Digital Thermometer for Covid-19 Detection
During the COVID-19 epidemic, taking temperatures has been a major focus. The aim of this project is to implement a prototype of a cheap and high reliability digital temperature measurement device with the aid of Arduino Nano, Infrared temperature sensor (MXL90614), OLED 128 X 64 (0.96-inch screen size), IR sensor and buzzer. This thermometer uses an infrared sensor MXL90614 to detect the body temperature and then sends the reading to the microcontroller. If there is no human presence nea...
Implementation of an Intelligent Motion Detector
This project is intended to provide a solution to a company's problem of developing a smart motion detection device for home and office security applications. The company intends to deploy 100s of these motion detectors throughout the Greater London Area. As a result, each motion detector will require a low power wide area network (LPWAN) wireless interface. Unlike traditional motion detectors, which detect only motion, the proposed motion detector will be able to detect motion direction (...
Development of a Low Cost Automatic Internet of Things Extension System
The aim of this work is to develop a prototype of a low cost automatic internet of things extension system that looks like a regular extension system but can be operated automatically. The extension system is controlled and monitored with the use of a smartphone application. The node MCU, ESP8266, 9V 1A power adapter, breadboard power supply USB – 5V/3.3V, 5V 4-channel relay, and 1602 LCD with I2C are used in the design consideration and execution. The solution is low-cost, and it ...
HVAC VS HVDC Power System: Contemporary Development In HVAC And HVDC Power Transmission System
Abstract: The ability to transfer power in HVAC (High Voltage Alternating Current) system has undergone limitation by reactance when compared with the fact that systems of HVDC (High Voltage Direct Current) can be accumulated to thermal limitation of the conductor. The transfer of power capabilities in HVDC and HVAC systems are compared with reference to their performance in different situations. Technological analysis conversion of existing alternating current (AC) lines into direct curre...
Design and Implementation of Real Time Pricing System in Smart Grids
This paper focuses on incorporating a real time pricing in smart grids system. This scheme of real time pricing makes it possible to manage the load from the demand side or consumer side. This would provide several benefits to the domestic consumers too, apart from industrial consumers. In addition to conservation, real time pricing also comes along way in protecting and preserving the quality of equipment used by the power utility company. Real time distribution aims towards a unifo...
