The JW-SWS-AQ(LC36) Gas Detection Weather Station is an integrated environmental monitoring system designed to measure outdoor air pollutants, selected gases and meteorological conditions at the same monitoring location.
Unlike a conventional weather station that measures only wind, temperature, humidity, rainfall and atmospheric pressure, this system can combine meteorological sensors with configurable gas and air quality monitoring modules. The resulting data helps users evaluate not only the concentration of pollutants, but also the weather conditions that may influence their movement, dilution, accumulation and potential source direction.
The station is suitable for urban air quality monitoring, industrial perimeter monitoring, construction sites, environmental research, transportation infrastructure, ports, mining areas, waste treatment facilities and distributed environmental IoT projects.
What Is a Gas Detection Weather Station?
A gas detection weather station is an environmental monitoring system that combines gas or air pollutant sensors with meteorological instruments.
It can collect gas concentration data together with parameters such as:
Wind speed
Wind direction
Air temperature
Relative humidity
Atmospheric pressure
Rainfall
Solar radiation
This combined information is more useful than isolated gas measurements because outdoor pollutant concentrations are strongly affected by local weather conditions.
For example, an increase in gas concentration during a stable low-wind period may indicate pollutant accumulation. A concentration increase associated with a particular wind direction may help project operators investigate a possible emission source.
The JW-SWS-AQ(LC36) is designed to support this type of continuous environmental observation and data correlation.

Environmental Gas Monitoring Technologies
Outdoor gas monitoring systems may use different sensing principles depending on the target gas.
Electrochemical Gas Sensors
Electrochemical sensors are commonly used for gases such as CO, SO₂, NO₂, H₂S, NH₃ and O₃.
They can provide compact and relatively low-power monitoring, but their performance may be influenced by temperature, humidity, sensor aging and cross-sensitive gases.
Regular calibration and appropriate environmental compensation are important.
NDIR Gas Sensors
Non-dispersive infrared technology is commonly used for gases such as CO₂ and certain hydrocarbon measurements.
NDIR sensors can offer good selectivity for specific gases, but the selected measurement range and optical design must match the application.
Photoionization Detection
PID technology may be used for broad VOC monitoring.
A PID typically indicates the total response to ionizable volatile compounds rather than identifying every individual chemical. The response factor can vary between compounds.
Metal Oxide Gas Sensors
Metal oxide sensors may be used for trend monitoring and broad gas response applications.
They can be affected by humidity, temperature and multiple interfering gases, so they should not automatically be treated as reference-grade analytical instruments.
Particulate Matter Sensors
Optical particle sensors can estimate PM1.0, PM2.5 and PM10 concentrations by measuring light scattered by airborne particles.
Particle composition, humidity, fog and aerosol characteristics may affect the relationship between optical readings and reference mass concentration.
Typical Monitoring Architecture
A complete outdoor air pollution monitoring system may use the following architecture:
Gas Sensors + Air Quality Sensors + Weather Sensors → RS485 Modbus → Data Logger or RTU → 4G LTE or LoRaWAN → Cloud Platform
The station collects environmental data at the monitoring site. A data logger or RTU processes and stores the readings before transmitting them to a cloud platform or customer server.
Cities can deploy multiple stations across residential areas, roads, parks, schools and public facilities to observe local variations in weather and air quality.
A distributed network can provide more spatial information than a single central monitoring point.
The system can support broader Urban Environmental Monitoring System projects that combine air quality, weather, noise and other environmental indicators. JW-IoT describes its urban environmental solution as supporting the monitoring of air quality, noise, weather and other indicators for city management.
Industrial Perimeter Monitoring
Factories, chemical plants, refineries, power plants and industrial parks may install monitoring points around the facility boundary.
Wind direction and gas concentration data can help operators evaluate whether detected pollution may be associated with internal operations, surrounding sources or changing regional conditions.
The station can support:
Facility boundary monitoring
Process area observation
Environmental compliance support
Complaint investigation
Emission event review
Historical trend analysis
The system does not replace certified stack emission monitoring equipment or regulatory reference stations when those instruments are legally required.
Wastewater Treatment and Waste Facilities
Wastewater plants, landfills, composting sites and waste transfer facilities may generate odor-related or process-related gases.
Typical parameters may include:
Hydrogen sulfide
Ammonia
VOC
Wind speed
Wind direction
Temperature
Humidity
Monitoring gas and wind conditions together can support odor investigation and operational management.
Construction and Demolition Sites
Construction projects may monitor:
PM2.5
PM10
Wind speed
Wind direction
Noise
Temperature
Humidity
Wind information can help users understand whether increased particulate readings may be related to on-site activities or external dust transport.
Mining and Quarry Monitoring
Mines, quarries and material handling facilities can use distributed monitoring points for dust, weather and selected gas observation.
Applications may include:
Mine boundary monitoring
Haul road dust monitoring
Crushing and screening areas
Stockpile areas
Coal handling facilities
Port loading areas
Roadside and Transportation Monitoring
Roadside stations can combine traffic-related pollutants with meteorological conditions.
Possible monitoring parameters include:
CO
NO₂
O₃
PM2.5
PM10
Wind speed
Wind direction
Temperature
Humidity
The station may be installed near roads, logistics centers, tunnels, ports, airports and transportation hubs according to project requirements.
Ports and Coastal Industrial Areas
Ports may experience pollution from ships, cargo handling, vehicles, storage areas and nearby industrial operations.
Weather and wind data are particularly important in coastal areas because sea breezes and changing wind directions can alter pollutant transport patterns.
Campus and Research Projects
Universities and research institutions can use the system for:
Air quality research
Urban microclimate studies
Pollutant dispersion studies
Environmental education
Sensor comparison
Distributed sensing experiments
Raw data access, Modbus registers and API integration can be configured according to project requirements.
Environmental Monitoring vs Safety Gas Detection
The JW-SWS-AQ(LC36) is designed primarily for environmental monitoring, outdoor trend analysis and IoT data collection.
It should not automatically be treated as:
A personal gas detector
A confined-space alarm
A fire and gas safety system
An occupational exposure alarm
A life-safety instrument
An explosion protection device
A legally certified emergency warning system
Where personnel safety, explosion risk or legally mandated gas alarms are involved, the complete system must use appropriately certified sensors, alarm controllers, installation methods and safety procedures.
The environmental monitoring station must not be used as the sole life-safety or emergency alarm device unless the selected configuration and complete system have been specifically evaluated and certified for that purpose.

Installation Recommendations
Select a Representative Location
Install the station where the readings represent the intended monitoring area.
Avoid locations directly beside:
Exhaust outlets
Air-conditioning outlets
Walls
Large heat sources
Localized dust piles
Frequently opened doors
Obstructions that block airflow
An intentionally source-oriented monitoring point may be installed near a suspected source, but it should be identified as such in the monitoring plan.
Avoid Airflow Obstruction
Wind sensors should be installed in an open position with minimal interference from buildings, trees, poles and other instruments.
Incorrect wind sensor placement can make pollutant source analysis unreliable.
Use Appropriate Sampling Height
The sampling height should be selected according to:
Monitoring objective
Local standards
Pollutant source height
Human exposure requirements
Roadside or industrial conditions
Surrounding obstacles
There is no single mounting height suitable for every application.
Protect the Gas Inlet
The gas sampling inlet should be protected from direct rain, insects, debris and standing water without excessively restricting airflow.
Do not cover the inlet with an unapproved filter or enclosure.
Separate Heat Sources
Solar panels, communication cabinets and equipment that generate heat should not directly influence temperature or gas sensor measurements.
Provide Stable Power
Outdoor systems may use:
Grid power
DC power
Solar panel and battery
Hybrid power supply
Solar system sizing should consider sensor consumption, communication frequency, local solar radiation, battery reserve days and seasonal conditions.
Use Proper Grounding and Surge Protection
Long outdoor cables, metal poles and exposed installations may be vulnerable to lightning and electrical surges.
Grounding, surge protection and local electrical practices should be included in the project design.
Calibration and Maintenance
Gas sensors require more maintenance than standard meteorological sensors.
A maintenance plan may include:
Visual inspection
Inlet cleaning
Zero check
Span check
Calibration
Sensor replacement
