Abstract

The invention relates to an air quality monitoring node based on ZigBee wireless technology. The traditional equipment has high cost and limited monitoring range. The air quality monitoring node of the invention comprises a power management module, an air quality parameter acquiring module, a microprocessor module and a ZigBee wireless communication module, wherein the power management module supplies power for the air quality parameter acquiring module, the microprocessor module and the ZigBee wireless communication module; a plurality of transducers in the air quality parameter acquiring module output signals to the microprocessor module after being converted by an I / V switching circuit; and the ZigBee wireless communication module is connected with a serial peripheral interface of the microprocessor module. The invention has the advantages of strong real-time property, multiple data types, wide covering area, strong communication capacity and high transmission speed.

Description

technical field [0001] The invention belongs to the technical field of wireless communication and embedded systems, in particular to an air quality monitoring node based on ZigBee wireless technology. Background technique [0002] Air quality is an important symbol to evaluate the quality of urban environment, and air quality monitoring is an important means of air quality protection and pollution control. Through air quality monitoring, it is possible to understand and evaluate the ambient air quality and provide a basis for urban planning. The research and development of a networked and intelligent real-time air quality monitoring system has become a hot issue. [0003] Existing air quality monitoring methods can generally be divided into two types: 1) Portable air quality monitoring instruments are used, manual sampling, and laboratory analysis are used. This method is mostly used for indoor air quality monitoring. Although it is more convenient to move, it is not It is ...
