▷ The Importance of Energy Consumption Prediction in Data Centers

➡️  #EnergyConsumption #EnergyPrediction #DataCenter In the digital age, data centers are a key piece of the technological infrastructure that drives the global economy. From managing large databases to cloud services, these centers consume large amounts of energy, making it crucial to have a good energy consumption prediction. Here we will explain why it is important to have a good energy consumption prediction in data centers. ➡️ Reducing Costs Energy consumption in data centers can be a significant cost for companies. Therefore, it is important to have a good energy consumption prediction to be able to plan and control costs efficiently. A good energy consumption prediction will allow companies to allocate budgets and plan appropriately, which will help reduce long-term costs. ➡️ Reducing Environmental Impact In addition to costs, data centers also have a significant impact on the environment. Generating energy for data centers often involves burning fossil fuels, contributing to gr

▷ The Social Cognitive Theory #SCT applied to reduce sedentarism in citizens

➡️  #SCT #SocialCognitiveTheory #Sedentarism Sedentarism is a growing concern in today's society due to its negative effects on health and well-being. However, the Social Cognitive Theory offers a solution to reduce it through a series of strategies based on human behavior. ➡️ According to this theory, human behavior is influenced by social perception, that is, how we perceive others and how they perceive us. In the case of sedentarism, one way to reduce it is through the creation of a social culture that values and promotes physical activity. ➡️ One way to achieve this is through education and awareness about sedentarism, physical activity, nutrition, quality of life, among other health-related aspects. Creating awareness campaigns about the importance of maintaining an active lifestyle can help influence social perception and motivate people to change their sedentary behavior. ➡️ Another strategy is the creation of programs and physical activities that are accessible and attracti

▷ What is the MQTT protocol?

➡️  #MQTT #IoT #SensorNetwork The  #MQTT  (Message Queuing Telemetry Transport) protocol is a lightweight communication protocol designed to facilitate communication between IoT (Internet of Things) devices. It was developed in 1999 by Andy Stanford-Clark and Arlen Nipper and has become one of the most widely used protocols in the IoT world. ➡️ How does MQTT work? MQTT works with a publish/subscribe model, in which devices connect to a centralized broker or server and send and receive messages. The protocol uses an asynchronous communication model, which means that devices can send messages at any time, without needing an immediate response. In addition, MQTT uses a "topics" model, which allows devices to publish and subscribe to messages related to a specific topic. For example, a device could publish messages related to the "temperature" topic, while another device could subscribe to that same topic to receive the messages. ➡️ What are the advantages of MQTT?

▷ Gesture Recognition Touch Sensor

  ➡️  #GestureRecognition #TouchSensor #DFRobot About this item This sensor module integrates gesture recognition and touch detects functions in one piece, and provides an adjustable detection range within 0~30cm. When connected to your microcontroller, it can detect 5-way touch signal and 7 kinds of gestures: move left, move right, move forward, move backward, pull up, pull down, pull and remove. The sensor is equipped with the function of auto-sleep and wake up. The module comes with the gesture recognition algorithm and provides simple and reliable data output. Use the sensor to directly communicate with upper computer or micro-controllers like Arduino and Raspberry Pi via serial port. The onboard 5-way touch pad on the sensor can be directly used to detect touch, or you can extend the touch pad with wires to make it perfectly fit in your application. The outer shield for the sensor retains the advantages of Gravity series as well as makes the sensor more durable. This sensor can be

▷ Indoor Hydroponics Growing System
