This sensor module is a professional small-scale instrument that integrates meteorological and air quality monitoring. It is a grid based application
Product details
1、 Product Introduction:
Micro air quality sensor integrates meteorological and air quality monitoring, and is a professional small-scale instrument applied in grid for environmental monitoring. It can monitorPM2.5，PM10Noise and eight major air pollutants, such asCO，CO2，NO，NO2，SO2，O3，H2S，H2And volatile gasesTVOCIn addition, seven meteorological parameters including wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall, and light intensity can be measured.
2、 Product advantages and applicable scenarios:
Adopting modular design, various measurement parameters can be flexibly combined and configured according to the actual needs of customers, with the advantages of small size and low cost, suitable for smart cities, smart street lights, urban environmental monitoring stations, campuses, research institutions and other venues.
