Wireless digital platform for environmental gas monitoring

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.
