At 7 AM, your smart wristband vibrates to wake you up; before leaving, the smart door lock automatically recognizes your fingerprint to unlock; during your commute, the in-car system reports real-time traffic conditions; at work, the smart coffee machine brews your hot drink—these everyday scenarios are powered by the same core engine: embedded technology. This … Read more
Wi-Fi HaLow Wi-Fi HaLow, with its long-range, low-power wireless communication technology, brings a revolution to ocean current monitoring. Wi-Fi HaLow supports buoy sensors, unmanned surface vehicles, and underwater detectors to continuously transmit real-time data on temperature, salinity, and fluid dynamics—even across vast ocean areas. In regions where traditional Wi-Fi or cellular networks cannot reach, HaLow … Read more
LoRa&IoT For Semtech, there is a seemingly “sweet” trouble. That is, the recognition of their product LoRa far exceeds that of their company name Semtech. However, the “awkward” part is not just this. As two of the most promising low-power wide-area network communication technologies in China, NB-IoT and LoRa have always been compared, with many … Read more
Author / Yuyou Caicai Word Count / 4200 Energy is everywhere around us. Light, heat, wind, waves, sound, electromagnetic radiation, and mechanical vibrations are all forms of energy. If IoT devices could free themselves from the limitations of power sources and batteries, relying entirely on harvesting energy from the environment for communication, true ubiquitous connectivity … Read more
Author: Zhao Xiaofei IoT Think Tank Original Introduction With the further development of environmental energy harvesting technology, passive IoT technology can not only provide energy sources for backscatter communication nodes that require only microwatt-level power consumption, but also support NB-IoT, LoRa, and other low-power wide-area network (LPWAN) terminals in certain scenarios, allowing previously battery-dependent nodes … Read more
