Smell machine -- Innovative city odor grid monitoring system based on MEMS sensing technology

Xiaodong Zhu, Fengmin Huang, Yi Zhou

Abstract


As one of the important indicators of urban environmental quality, city odor has an important impact on residents’ quality of
life and city image. Traditional odor monitoring methods have problems such as sampling diffi culty, time delay and low spatial resolution,
which can not meet the needs of accurate and real-time monitoring of urban odor. Based on microelectromechanical system (MEMS) sensing
technology, this paper proposes an innovative city odor grid monitoring system, the sniffi ng machine. The system uses the array of micro
gas sensors, and arranges the sensors in diff erent areas of the city to form a grid layout, so as to realize the comprehensive monitoring of city
odor. It provides a new idea and method for urban environmental management and improvement, and helps to promote the improvement of
urban environmental quality and the improvement of residents’ quality of life.
