This study proposes an ARM based air quality module placed to public transport vehicles for analyzing the effect of PM2.5 and PM10 particles in cities real-time using Internet Things. The STM32 microcontroller is used obtaining data from PM, humidity, temperature sensors. collected sensors are sent i.MX6UL microprocessor RS-485 connected internet portal with Ethernet module. sends Microsoft Azu...

The offset as the average value of a variable plays an important role in signal processing and system design. Offset boosting can be realized by non-bifurcation parameter or initial condition. In this work, symmetric coexisting attractors with opposite polarity 2D hyperchaotic map multiple modes are proposed, where controlled both condition parameter, result, alternatives competition show up. C...

Precision agriculture is the trend of modern agriculture, and it is also one of the important ways to realize the sustainable development of agriculture. In order to meet the production requirements of precision agriculture-efficient use of agricultural resources, and improving the crop yields and quality-some necessary field information in crop growth environment needs to be collected and moni...

Abstract In this study, the STM32 microcontroller is used to drive a passive matrix (PM) Micro-LED through two-wire serial transmission and row-column integration. exhibits superior properties, including simple-to-operate, cost-friendly, flexible programming. Moreover, it has lower cost more straightforward implementation for testing quality of device realizing graphics. design, connection betw...

The baseband signal of the 406 MHz COSPAS-SARSAT emergency beacon is a 144-bit or 112-bit data with 0 and 1 code, including information bits error correcting check bits. In order to improve coding efficiency for transmitter in STM32 micro-controller, this paper proposes calculation method first BCH code (BCH-1) second (BCH-2) COSPAS-SARAST transmitter. First, conduct process by 64-bit integral ...

Whether in the monitoring of critically ill patients such as shock, respiratory failure, brain injury, or major anesthesia surgeries, it is necessary to evaluate patient’s pO2 and pH. An optical fiber sensor presented capable presence oxygen partial pressure (pO2) pH real-time. The based on fluorescence sensing polymer immobilized oxygen/pH-sensitive membranes covalently attached probe. design ...

Abstract The traditional electric window opener has the problems of low efficiency and single control mode. In view above shortcomings, an intelligent system based on multi-sensor fusion is designed. uses data acquisition, processing, wireless communication, remote control, other technologies to realize real-time monitoring environmental status through temperature, light intensity, smoke, rain,...

35 S, and 28 S RNA of tumors is characterized by a lower adenylic acid content and a higher cytidylic acid content than that of nontumor tissues (3). In addition, it was found that the isotope content of the dinucleotides GC and GU of hepatomas was significantly higher than that of normal liver (18). For determination of whether these differences represented isotope effects or seg mentai differ...
