Click the blue text above: IoT Inn to follow us. In previous sections, we used the LED light, buzzer, and relay components, driven by the GPIO output function of STM32. In this section, we will learn about the GPIO input function. When an external button is pressed, the microcontroller can detect it in real-time. Buttons … Read more
Click the blue text above: IoT Inn In the previous section, we learned about the independent key operation of the microcontroller. In fact, we used a polling method, which consumes MCU resources as it constantly checks for key presses. In this section, we will use interrupts to implement key operations. 01 Basic Knowledge 1Introduction to … Read more
Author: Peng Zhao (Founder of Zhiciph, Co-founder and Partner of Yunhe Capital) IoT Think Tank Original This is my 324th column article. The integration of large AI models with hardware is in full swing, but it seems to be facing resistance on the B2C consumer side. According to The Information, former Apple design chief Jony … Read more
The Internet of Things (IoT) is creating a new world, a world that is quantifiable and measurable. In this world, people can better manage their lives, cities can better manage their infrastructure, and companies can better manage their businesses. This new intelligent interconnected world will fundamentally change society and consumers, leading to profound transformations across … Read more
Introduction: As more and more IoT devices connect, they generate massive amounts of data. However, sending all this data to the cloud for processing may be counterproductive. Edge computing pushes data processing closer to the source (sensor devices) instead of sending it to a centralized cloud located thousands of miles away. In recent years, low-cost … Read more
He Qin, Xie Yinggang, Zhao Minglang (Beijing Information Science and Technology University, School of Information and Communication Engineering, Beijing 100101) Abstract: In response to vehicle pollution emissions and real-time vehicle monitoring issues, a vehicle information self-inspection monitoring system based on Internet of Things (IoT) technology is designed. The system uses an OBD simulator to replace … Read more
Internet of Things & Big Data Cloud Computing & Artificial Intelligence Is there a connection between the Internet of Things, Big Data, Cloud Computing, and Artificial Intelligence? How are they combined and applied in real-world scenarios? To illustrate, consider the human body: our organs perceive everything in the world (Big Data), which is aggregated through … Read more
Overview With the development of the Internet of Things (IoT), more and more devices need to connect to the cloud. These devices include various instruments, industrial equipment, collection devices, and sensors, most of which use serial ports (RS232, RS485). Therefore, IoT gateways such as serial-to-TCP and serial-to-WiFi can be used to transmit data to the … Read more
The commonly used wireless transmission methods for medical IoT include 5G technology, WiFi technology, and Bluetooth communication technology. From a technical perspective, 5G and WiFi have advantages such as high bandwidth and fast transmission speeds, primarily used for communication between computers, smartphones, etc. Bluetooth communication technology has the benefits of low power consumption and fast … Read more
In the communications field, technological pursuits are constantly advancing. When it comes to the Internet of Things (IoT), various communication manufacturers have already begun to tantalize us. There are many wireless communication technology standards for IoT, which can be divided into two categories based on transmission distance: one category includes Bluetooth/BLE, WiFi, Zigbee, and Z-Wave, … Read more
