Background The COVID-19 pandemic which started in November 2019 and since then has led to multiple lockdowns aimed towards controlling the pandemic, these lockdowns contributed to major changes in individuals’ lifestyles including eating patterns and restriction of physical activity due to continues house confinement. Such changes have significantly contributed to weight change, with increasing rates of obesity in the UAE, COVID-19 have posed a major concern to the country’s obesity levels. Aim To measure the prevalence and investigate the views related to weight change among adults in the UAE during the COVID-19 pandemic. Methods A cross-sectional study was conducted through a self-administered online questionnaire distributed using social media platforms between February 15th and March 14th, 2021. The sample size was 439 adults in the UAE (18–59 years), collected by volunteer sampling. Analysis was done using SPSS with a significance of 5.0%. Exclusion criteria included pregnancy and bariatric surgeries history. Results 51.1% of participants gained weight, 36.2% lost weight and 12.7% maintained their weight. Meal consumption frequency and weight gain were correlated. Consuming fast food resulted in 65.7% of participants gaining weight. 66.2% of people who lost weight during the COVID-19 pandemic did exercise. Stress management and sleeping patterns were not contributing factors to the weight change. 64.4% of the participants who were not satisfied with their weight and believed that they need to make changes in their lifestyle received no guidance from professional personnel to reach their desired weight. Conclusion In this study, the majority of participants have witnessed an increase in weight. UAE health authorities must provide guidance and support to the population via structured nutritional programs and lifestyle awareness campaigns.

Fire alarm and detection systems play a significant role in preventing life and property damages from fire disasters. Many of the existing fire alarm systems could incur significant expense that is not moderate for low-income users. The main purpose of our project is to design and implement a fire detection and control system that can be produced at a low cost at effective and competitive usage with a main objective of saving life and property damages. The system will be able to detect the temperature of the environment, the presence of fire flame, the gas level and send SMS alert to a user through an inbuilt GSM number. The remote user responds to the received fire STATUS information by turning ON/OFF a fire extinguisher or protection equipment installed at the fire site. The system gets power from a 12 V control supply utilizing a step-down transformer; the Arduino Uno Microcontroller is the core part of the system and it is interfaced with the GSM SIM900 module, flame, temperature and smoke sensors and the fire extinguisher equipment.
