In this work, we demonstrated an open access Wi-Fi wireless digital platform for environmental gas monitoring based on different types of gas sensors with SPI digital output. The digital platform consist space for four sensors. Used for data exchange between drivers of gas sensors and wireless digital platform, the open data exchange protocol for digital intellectual sensors (DIS) gives possibility to work with any type of gas sensors (electrochemical, metal oxide, thermocatalytic, optical etc.). Developed system architecture of wireless digital platform has also an advantage “hot swap” (PnP) of gas sensors. Visualization of gas concentrations from the wireless digital platform is possible to be received on-line through any web application available on most mobile device (laptop, smart phone, etc.) using widely available free internet browsers (Opera, Google Chrome, etc.) without necessity of downloading any additional user or service software.

In this paper, we present development of digital intellectual sensors (DIS) for gas sensor applications based on open digital data exchange protocol using National Standard of Russian Federation for intelligent gas sensor modules. For demonstration possibilities of intellectual sensors in paper described electronic digital driver for oxygen electrochemical gas sensor. In this work a lot of attention gave to questions of standardization and unification for creation a commercially available system for gas analytical instruments industry.

We study the properties of luminescent diamond particles of different sizes (up to ∼1.5 μm) containing multiple NV-centers. We theoretically predict that the average liftetime in such particles is decreased by several times as compared to optically small subwavelength nanodiamonds. In our experiments, samples were obtained by milling the plasma-enhanced chemical vapor deposited diamond film, and characterized by Raman spectroscopy and darkfield spectroscopy methods. Time-resolved luminescence measurements of the excited state of NV-centers showed that their average lifetime varies from 10 to 17 ns in different samples. By comparing this data to the values of the lifetime of the NV-centers in optically small nanodiamonds, known from literature, we confirm a severalfold decrease of the lifetime in resonant particles.

The focus of this work is made on standardization and unification process during the design and production of a commercially available system for gas analytical instruments industry. The implementation of Wireless Sensor Network (WSN) platform for hazardous gases detection includes the development of software which relies on the digital data exchange protocol using National Standard of Russian Federation. The goal of software is to support hardware electronics for smart gas sensitive modules and Wi-Fi wireless digital platform. This idea allows the user to work with the web application available on most mobile device (tablet PC, smart phone, etc.) using widely available free internet browsers (Mozilla Firefox, Google Chrome, etc.) without necessity of downloading any additional service software.
