With increase in global warming and ever changing temperature the rate of water in dam and temperature affects millions of people and damages the economy if any incident were supposed to happen due to human error so with the help of our automated dam system we have very efficiently solved it with the help of temperature sensor and advanced Ultrasonic sensor we have automated the dam gate opening process so that the gate of dam is automatically opened when there are chances of dam being overflowed or damaged. Using ultrasonic sensor and a temperature system to simultaneously support the decision of dam door functionality helped in overcoming accidental and falsetriggered data. Using these two in co-relation makes system less prone to error and increases the efficiency by multiple times.

Room Lighting

The use of air conditioners (AC) and lighting that do not suit the needs and excessive results in a lack of comfort and high use of electrical energy. Ultrasonic Sensor of SRF-04 functions to find out the number of people in the room, temperature sensor of DHT 22 functions to calculate the temperature and humidity inside and outside the room, Light Intensity sensor of GY-302 functions to read the level of light intensity in the room and micro controller of Arduino Mega 2560 functions to process all input sensors become the command for operating the AC units and lights. The AC and lighting control system working well and can determine the time and number of AC and light that is needed. Those are based by Indonesian room comfort standards so that it can increase the comfort of the room in terms of cooling systems and room lighting with a temperature of 22oC to 25 oC and light intensity of 300 lux.

The rate at which the novel virus Covid-19 spread across the world in an alarming rate with high rate of death of the infected persons is quite disturbing, hence the need to checkmate its spread by quickly identifying persons with the symptoms of this viral infection. This paper discusses the development of an automated low-cost non-contact temperature scanner and sanitizer. The system automatically detects a human being, scans for temperature, and sanitizes the person with no interference required. The circuit for the system comprises an Arduino microcontroller, LCD display, relays, ultrasonic sensors, temperature sensor, 12v DC pump motion sensor and a high pressure 12v DC pump. The temperature sensor (MLX90614) senses the temperature, certifies that the value is within the specified range as controlled by its ultrasonic sensor and displays the temperature on the LCD. Thereafter, an ultrasonic sensor activates the 12V DC pump to dispense the sanitizer. At the disinfectant chamber, the motion sensor will trigger the high-pressured DC pump when it senses movement, it dispenses the body sanitizer through the nozzles. C++ was used to program the Arduino in Arduino user interface. The entire process takes 60seconds and it helps to maintain personal preventive measures as well as detecting a possible symptomatic person as fever with high temperature which is one of the major symptoms of Covid-19. The device has been tested and works effectively, and it will be very useful for any organization with one or more buildings. It can be positioned at the entrance of buildings to sanitize and scan all staff and visitors against Covid-19. Keywords: Arduino, Covid-19, Hand sanitizer, Ultrasonic sensor, Temperature Scanner

This study aims to build an aquaponics automation tool to simplify the control of fish and vegetable cultivation. The objects that were taken in this study were nile tilapia and choy sum. In this study, testing was carried out in an aquarium and hydroponic pipe to control nutrition, water turbidity, light, pH, feed, and temperature. The main tools used to build this automation include Arduino ESP-32, GY-302 Ambient Light Intensity Sensor, DFRobot Gravity Analog pH Sensor, DS18B20 temperature sensor, 3-6V DC R140 DC motor, Relay Module6 Chanel 12V, RTC Module. DS130 and SR04 Ultrasonic Sensor. After the system testing process, it can be concluded that this tool can support the process of cultivating nile tilapia and choy sum properly and make it easier for farmers to monitor aquaponics.

The World

Automation is nowadays a new trend of Electronics. This automation has been implemented by the help of microcontrollers. If a microcontroller is programmed efficiently then it is capable to work efficiently as human. This era of automation has reduced so much human efforts. In this century some changes has taken place in the field of technology. The most important of those is the use of digital circuits in everywhere. The world of digitization has made things easier than before or we can say it has reduced human error in most of the areas. In our research we have made a digital thermometer by using AT89C51 microcontroller. The other components we have used are LM35 temperature sensor, Analog to Digital converter IC (ADC0804), MAX-232 IC chip for serial communication with the microcontroller and LCD display to display the temperature. We hope that this research paper will be helpful to scientific improvement in the field of making Digital thermometers to a great extent.

According to the current pandemic situation body hygiene maintenance is the top most priority. An automatic hand sanitizer dispenser is automated and alcohol based the most important criteria is that it is touch-less machine, which will be used in hospitals, schools, work places and much more. Concentration of 70% alcohol can kill corona-virus in hand, it is scientifically proven. Here an ultrasonic sensor detects the human hand whenever placed near the machine and it will also check the distance between hand and the machine dispenser. Contactless temperature sensor is here to check the body temperature of a person and the result is pump running to pump out the hand sanitizer. This machine serves the main purpose of creating a touch-less mechanism, which maintains proper hygiene methods.

Abstract We are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor. In a warming climate, individual organisms may be able to shift their thermal optima through phenotypic plasticity. However, such plasticity is unlikely to be sufficient over the coming centuries. Resilience to warming will also depend on how fast the distribution of traits that define a species can adapt through other methods, in particular through redistribution of the abundance of variants within the population and through genetic evolution. In this paper, we use a simple theoretical ‘trait diffusion’ model to explore how the resilience of a given species to climate change depends on the initial trait diversity (biodiversity), the trait diffusion rate (mutation rate), and the lifetime of the organism. We estimate theoretical dangerous rates of continuous global warming that would exceed the ability of a species to adapt through trait diffusion, and therefore lead to a collapse in the overall productivity of the species. As the rate of adaptation through intraspecies competition and genetic evolution decreases with species lifetime, we find critical rates of change that also depend fundamentally on lifetime. Dangerous rates of warming vary from 1°C per lifetime (at low trait diffusion rate) to 8°C per lifetime (at high trait diffusion rate). We conclude that rapid climate change is liable to favour short-lived organisms (e.g. microbes) rather than longer-lived organisms (e.g. trees).
