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
