Multi in one weather sensor

The XHQX-3A series micro air quality station integrates meteorological and air quality monitoring, and is a professional small-scale instrument applied to environmental monitoring in a grid. It can monitor PM2.5, PM10, noise, and eight major air pollutants such as CO, CO2, NO, NO2, SO2, O3, H2S, H2, and volatile gas TVOC. In addition, it can also measure seven meteorological parameters including wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall, and light intensity.
The equipment adopts modular design, and various measurement parameters can be flexibly combined and configured according to the actual needs of customers. It has the advantages of small size and low cost, and is suitable for smart cities, smart street lights, urban environmental monitoring stations, campuses, research institutions and other venues.
