▷ 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 sens...

▷ Data visualization: of Temperature, Humidity, and CPU Temp.

For this post, two sensors have been deployed for real-time data collection, currently operational in the city of Guayaquil: one for humidity and another for temperature. Both sensors utilize LoRA technology to transmit collected information to a Gateway. This Gateway serves as a central connection point, receiving data from the sensors and forwarding it to the Google Cloud platform via LTE cellular connectivity. Leaflet viewer with OpenStreetMap Leaflet viewer with OpenStreetMap Once the data is stored on the Google Cloud platform, a customized web interface has been developed. This interface facilitates the visualization and analysis of the sensor-collected data, offering users a clear and easily accessible representation. In this post, we'll explore how to visualize real-time data from Google Cloud using JavaScript and the powerful charting library, Chart.js. The goal is to create an interactive environment that visually...

▷ The Importance of Soft Processors in #FPGAs for Customized Digital Circuits

➡️ #FPGA #VHDL #SoC # System-on-Chip #Processor #SoftProcessors #DigitalCircuits #DigitalSystems FPGAs (Field-Programmable Gate Arrays) are programmable electronic devices that allow for the creation of customized digital circuits. Unlike ASICs (Application-Specific Integrated Circuits), which are integrated circuits specifically designed for one application, FPGAs can be programmed and reprogrammed to perform different tasks. ➡️ One of the most important advantages of FPGAs is their ability to implement soft processors, which are processors that are implemented in the FPGA using a hardware description language (HDL). Soft processors allow designers of integrated systems to create more complex and flexible systems than would be possible with conventional integrated circuits. ➡️ The importance of using soft processors in FPGAs lies in the ability to create highly customized integrated systems, tailored to specific user needs. Soft processors can be optimized for a...

▷ 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, contribut...

▷ 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? MQTT...
