This also helps in minimizing costs and environmental impacts while maximizing system reliability, resilience, and stability. A network of physical objects contains embedded technology to communicate and sense or interact with their internal states or the external environment. In general, “smart city”...
• OFF-state diagnosis for the analog current sense option (‘E’ types) Introduction5 VIPowerTM Zero series ST’s VIPowerTM Zero series offers innovative and high-performance protected switches for driving high power applications. This series covers today’s growing demand for intelligent powe...
This is done mainly for two purposes: no external sensor is needed for this system, and the sensing photovoltaic cell will sense the same conditions as the rest of the solar panel (dust, illumination). Energy storage is achieved by a charger chip and a battery. In order to achieve ...
Valve’s class-based shooter, Team Fortress 2, has achieved legendary status thanks to its varied game modes, impeccable sense of fun, and being home to more hats than the world’s millinery stores combined. The whole game is free-to-play these days, from the standard shoot-everything-that...
(OFDMA), which assigns slices of the frequency spectrum to different users, avoiding interference among the users and increasing the spectral efficiency of the system. WiMAX is an attractive solution in the sense that its structure is much less sophisticated compared to rival cellular standards such...

In ref. [16], a sensor unit system was designed as a standalone wireless sensor to sense temperature and humidity. Their data can be sent over a low-energy Bluetooth transmitter and be received by the receiver node. The recorded data can be seen using portable monitoring devices, such as ...
The proposed wireless sensor node comprises four units; an air-quality sensor, a processor, a wireless transceiver, and a battery charger, as shown inFigure 2. The CO2air-quality sensor is used to sense indoor CO2concentration. The main component is a microcontroller to be used for data acqui...
The system was built using a ThunderBoard Sense 2 wireless sensor board with a built-in CO2 sensor Appl. Sci. 2022, 12, 10784 3 of 23 and other sensors such as TVOC, ultraviolet index, temperature, relative humidity, air pressure, ambient light, and noise level. The sensor node ...
The 𝑚𝑎𝑐𝑀𝑖𝑛𝐵𝐸macMinBE corresponds to the minimum value of the Backoff Exponent (BE) configured in the device. Next, the device performs the CCA process to sense for activity in the channel and decide if it is assed busy or free. If the channel is detected busy, ...
