air quality transmitter (outdoor type)

summarize JCAQ-8 air quality transmitter (outdoor type) is an instrument developed to monitor six pollutant parameters, such as PM2.5, PM10, CO, SO2, NO2 and O3, as well as air temperature and relative humidity. The main function is to monitor the conventional pollution factors in the air continuously and online for 24 hours, and provide the analyzed data to the Environmental Protection Bureau as a reference for air quality and assist environmental protection decision-making. In addition, hydrogen sulfide, volatile organic pollutants, total suspended particulate matter and other meteorological sensors (wind speed, wind direction, atmospheric pressure, rainfall and sunshine radiation) can be selected. Field of application The air quality monitoring micro-station can be applied to urban grid environmental monitoring and control, smart street lamps, scenic environmental monitoring, factories or mines, construction sites (site dust monitoring), urban roads, expressways, public places and other places involved in air quality monitoring. Product features 1. monitor six parameters of PM2.5, PM10, NO2, SO2, O3, CO, temperature and humidity as standard, commonly known as "two dusts and four gases", RS485 communication; 2. High precision and reliable performance, suitable for outdoor and industrial environment fields; 3. Realize the collection of various parameters, optional our wireless data collector, realize the automatic uploading of data to the network platform, and the mobile phone client can view the data in real time; 4. Real-time monitoring of atmospheric environmental data, low cost, suitable for grid distribution; 5. Small size, modular design and flexible layout; 6. GPS positioning can be selected to realize equipment tracking function; 7. Data acquisition adopts 32-bit high-speed processing chip, which is stable and anti-interference.
