It is a multi-element integrated meteorological sensor that can simultaneously measure major meteorological parameters such as atmospheric temperature, humidity, wind speed, wind direction, and air pressure. It also integrates a harmful gas detection module to monitor the concentration of typical pollutants such as CO, SO ₂, NO ₂, and O3 in the air in real time. This sensor has the characteristics of high measurement accuracy and fast response speed. It adopts serial output, which facilitates users to quickly obtain various environmental data through PC or external instruments. It is widely used in application scenarios such as smart cities, environmental monitoring, meteorological stations, and agricultural environmental monitoring.
