Wi-Fi Wireless Digital Sensor Matrix for Environmental Gas Monitoring

Abstract

In this work, we demonstrated an open access Wi-Fi wireless system for environmental gas monitoring based on different types of gas sensors with SPI digital output. Digital sensors matrix consist of four sensors with especially developed data exchange protocol for digital intellectual sensors (DIS) giving possibility to work with any type of sensors. System architecture has also an advantage “hot swap” of sensors. Visualization of gas concentrations received from the matrix is possible through any web application available on any mobile device (laptop, smart phone, etc.).
