Abstract— This work aims to achieve a functional system in terms of software and hardware to measure humidity with temperature and raining fall. Also, this system allows monitoring the date and time. We used Arduino Nano with the interfacing of the DHT22 sensor and a raindrop sensor placed in the local environment to measure the mentioned data. After designing the system that depends on the microcontroller Embedded on the Arduino board, we will display the data on a screen of the PC by the Arduino window (serial monitor) and display it on the LCD screen. This paper describes a simple portable design for humidity, temperature, and rain or no rain. The portable design can be made with a low cost of electronic components. It is efficiently and locally available so that it can be used to monitor weather conditions at any place. The test results showed that this system's component is small and can be packaged in a small plastic box. Besides, through the programming, we recorded the data on the Excel program, and at the same time. The data were recorded in a memory added to the manufactured system. The data obtained every five seconds are the (date, time, temperature, humidity, weather if rainy or not rainy). The system consists of two parts; the first part is inside the indoor, and it can be placed outdoor as needed and the second part is a rain sensor that can be placed outdoor. In case of rain, the buzzer and LED can be turned on to indicate the condition of rain.

Abstract This work intends to design and implement of a mobile system for gas detector and measuring the data of (relative humidity H%, temperature in Celsius &Fahrenheit) which can be used in homes or in the workplace such as laboratories. Specifically, this paper aims to answer how to design a prototype (software and hardware) for gas detection and its performance in terms of detecting both liquefied petroleum gas (LPG) and smoke, through the use of the MQ2 sensor, as well as measuring the humidity and temperature in ( oC, oF) by using the DHT11, through the connecting them with the Arduino UNO. The results of this work were display through serial monitor by Arduino window & at the same time it is displayed on the LCD screen, meaning the presence of a gas is detected or no gas is detected “Its alarm system by buzzer and red led”, in addition to displaying the value of temperature and humidity (oC, oF, H%). Also, through the programming process, the results of this work are displayed and stored on the Excel program which are (date, time, oC, oF, H%, ratio of gas detecting ppm), and on same time recorded data on a memory card which added portable device. The executing cost is ($17) which is very cheap.

In all facets of mechanical design, stress concentration is a crucial factor. It produces from common geometric defects in the structure. This study uses two different materials as the plate has a central cutout subjected to a stress of uniform load (1000 N): Aluminum alloy & Titanium alloy were analyzed. Then, for four cases of thickness, the finding of each one are compared using the following methods: Graphical, Analytical and ANSYS software. Where the (maximum, nominal) Stress, Stress Concentration Factor (SCF). Moreover, the total deformation is measured by measuring the percentage error. The results of the SCF are very close, and the highest error rate for both matters was at (10mm) thickness, which is for aluminum (4.063%) & titanium (3.839%). In addition, FEA can be stated to be a particularly efficient tool for quickly determining the stress created by various materials

The FEM is a computational method for solving a wide range of electric and mechanical engineering issues, including structural, heat transfer, thermal and fluid flow. The matter used in the present work is stainless steel with fixed dimensions(l=200,w=100, t=2)mm for a rectangular plate with central circular hole for five cases of diameter hole(10,15,20,25,30) mm. In the current paper resulted, may be conclusion a max. of stress happens on the holes angles for the five cases of (d/w) for the matter under study. Three method are used to analysis (FEA, Analytical and Graphical), it is observed that, if the ratio of (d/w) increases, the max. stress will be increased with decrease of SCF value for all the five cases for three type of calculation. The P.E.% was calculated in the current work and very close values were obtained, which was the lowest value(0.38%) and the highest is (4.03%) which is very little. It is a small value, which indicates the accuracy of the measurements for the three methods, we can say FEM is a powerful method for determining stresses in a variety of materials

The phenomena of resistance random access memory (RRAM) depending on the altering of resistance between at least two values has been found in materials such as transition metal oxides, some semiconductors or insulators materials, named as resistive switching. The developments on RRAM have been started due to its low power consumption, simple structure, high-density, high – speed resistive switching, impressive retention with small feature size. Regardless of the wide-ranging research, basic switching conduction mechanisms of the resistive memory structures are basically depending on the certain special materials. To improve the current structure performance, the Cellulose Acetate as a polymer was added to the active layer (cadmium selenide CdSe). The polymer material was used to form the second active coating to construct the Au/CdSe/polymer/Au as new structure. This material may enhance the cell performance by increasing the charges traps. This procedure leads to increasing resistance ratio (Rratio) and decreasing the working voltages of structure. A spin coating apparatus was used to coating the polymer layer on CdSe. The glass was used as a substrate and the first active layer deposited under vacuum by thermal evaporating system. The cell was sandwiched between the two electrodes in the same materials (Au) which deposited also under the same system. Bipolar resistive switch, in this memory structure, is observed in its switching operation. The zone of the upper electrode (Au) has a significant affect upon the resistive performance. This influence is became further in the big upper electrode zone (TEL=13.5mm2) where the high-resistance (HRS) are inversely related to the upper electrode zone (A). This occurs inducing more traps in case TEL (hanging sentence). Finally, the (Rratio) is directly proportional with the electrode zone (A). The compliance current (Icc=30mA) are used for protecting the structure from the damage. The current structure has many properties, such as Vset = 3.9V, VReset = -1.9V and Rratio about 176 in case of TEL. We conclude from this research that the embedment of a thin layer of a polymer which have been used in this research are improving the high density, enhancing high speed with low cost as well

This paper presents the design and executes a Dual Axis light tracking system. The system is designed to track the light in order to get maximum intensity from the light intensity sensor (LIS) GY-30 as they follow the direction light incident on it by using two servo motors, the motors can be rotate from (0o-180o) in four directions. This system consist of (LIS) and four LDRs where as it has been designed as shape like a cross and we fixed the (LIS) and LDRs then putted on a stand which fixed on plastic box that contain all work requirements. The LDRs have been employed to sense direction of the light which is directly connected to microcontroller (MCU) embedded in Arduino Mega. The MCU therefore commands any one of two Servo motor to re-orient the (LIS) either vertically or horizontally in order to stay straight to the light. The data of lux is display in the same time on LCD and on the PC by serial monitor or recorded on the Database for Excel, moreover the executing cost is ($20) which is relatively cheap. The system is programmed with Arduino IDE. Based on the results, the three cases proved efficiency, accuracy, reliability, and durability for our not expensive, and easy to maintain the system
