Air quality monitoring for intensive farming
Intensive livestock farming can create variable environmental conditions linked to animal housing, ventilation, manure handling and storage, feed operations and vehicle movements. Aernode provides continuous monitoring across relevant farm areas and site boundaries, helping operators follow changes in ammonia, particulate matter and other environmental parameters, review reported odour episodes and relate observed conditions to farm activity and meteorology.
Continuous insight for proactive environmental management
Environmental conditions around intensive livestock facilities can change with animal housing, ventilation patterns, manure handling and storage, feed operations, vehicle movements and meteorological conditions. Continuous monitoring provides a persistent record of parameters such as ammonia and particulate matter, helping operators identify recurring patterns and review how conditions vary across different areas and periods of activity.
Monitoring nodes can be positioned around livestock buildings, manure or storage areas, site boundaries and nearby receptors. Measurements can then be reviewed alongside farm activities and local meteorology to provide additional context for changing conditions and reported odour episodes. The resulting data supports operational review, mitigation planning and structured communication with authorities, neighbouring communities and other stakeholders.
Operational value of continuous intensive farming monitoring
Continuous environmental data helps operators review changing conditions, understand recurring patterns and support day-to-day environmental management around intensive livestock facilities.
Continuous environmental oversight
A distributed network provides an ongoing record of selected parameters across livestock buildings, manure handling and storage areas, site boundaries and other relevant locations, revealing variations that periodic measurements may not capture.
Better context for odour-related events
Measurements of ammonia and other relevant environmental parameters can be reviewed alongside manure handling, ventilation, farm activities and meteorological conditions to provide additional context when odour episodes are reported.
Active monitoring with configurable alerts
Configurable thresholds can highlight changes in monitored parameters, giving operators an additional signal to review farm activities, ventilation conditions, manure management or meteorological factors during relevant periods.
Evaluate operational and mitigation measures
Comparing measurements across locations and operating periods can help assess how environmental conditions change following ventilation adjustments, manure-management practices or other measures intended to reduce local impacts.
Structured data for reporting and communication
Consistent time-series records support internal environmental reviews, documented follow-up of reported events and evidence-based communication with authorities, neighbouring communities and other stakeholders.
A monitoring network designed around farm activities and receptors
Each deployment is configured around livestock buildings, ventilation outlets, manure handling and storage areas, site boundaries, prevailing winds and nearby receptors, so measurements provide useful context for day-to-day environmental management and the review of changing conditions.
Define the monitoring objectives
Identify the farm areas, site boundaries and nearby receptors most relevant to the monitoring programme, and define the parameters and environmental conditions the network should help operators review.
Configure and position the network
Select the relevant environmental parameters and position monitoring nodes around livestock buildings, ventilation outlets, manure handling or storage areas and site boundaries, taking prevailing winds and nearby receptors into account.
Establish the operational workflow
Connect measurements with dashboards, configurable alerts, meteorological data and reporting outputs so operators can compare locations, review changing conditions and reported episodes, and maintain a structured environmental record over time.
Parameters commonly monitored around intensive livestock farms
| Parameter | Why it matters in intensive farming environments |
|---|---|
|
NH₃
Ammonia
|
Ammonia is a key environmental parameter around intensive livestock farming and can vary with animal housing, ventilation, manure handling, storage and other farm activities. Continuous monitoring helps operators review concentration patterns across relevant areas and different operating conditions. |
|
PM₂.₅ / PM₁₀
Particulate matter
|
Particulate matter can be influenced by feed and bedding materials, ventilation exhaust, animal activity, vehicle movements and surrounding agricultural operations. Distributed monitoring helps compare dust conditions across farm areas, boundaries and nearby locations. |
|
H₂S
Hydrogen sulphide
|
Hydrogen sulphide may be relevant around manure and slurry handling or storage areas where anaerobic conditions can occur. Monitoring can provide additional information on concentration variations and context when changing or odour-related conditions are being reviewed. |
|
VOCs
Volatile organic compounds
|
Volatile compounds can vary with manure management, organic material, feed-related activities and other processes around livestock facilities. VOC indicators can provide additional context for changing environmental conditions and the review of reported odour episodes. |
|
Wind
Speed and direction
|
Wind speed and direction provide essential context for interpreting measurements around livestock buildings, manure areas, site boundaries and nearby receptors, particularly when reviewing spatial patterns or reported environmental episodes. |
Monitoring configurations are project-specific; NH₃, particulate matter, H₂S, VOC indicators and meteorological parameters are selected according to livestock activities, site characteristics and monitoring objectives.

Frequently asked
questions
Practical answers on ammonia monitoring, particulate matter, odour-related conditions, network design and environmental monitoring around intensive livestock facilities.
What types of livestock facilities can benefit from continuous air quality monitoring?
Continuous ambient monitoring is most relevant where concentrated livestock activity can create changing conditions around animal housing, ventilation outlets, manure handling or storage areas and site boundaries.
Typical applications include intensive poultry farms — such as broiler and laying-hen operations — pig or swine facilities and, depending on the project, dairy or cattle operations with concentrated housing and manure-management systems.
Aernode monitoring networks are configured around the actual farm layout, emission sources, surrounding receptors and environmental objectives rather than applying one standard layout to every livestock facility.
Which pollutants and environmental parameters are most relevant around intensive livestock farms?
Ammonia (NH₃) is usually the primary gaseous parameter, while particulate matter PM₁₀ and PM₂.₅ can be relevant around animal houses, feed and bedding activities and ventilation exhausts.
Hydrogen sulphide (H₂S) and VOC indicators may also be useful where manure or slurry management and odour-related conditions are important.
Temperature, relative humidity and especially wind speed and direction provide essential context for interpreting outdoor measurements. Aernode Sensor Kits allow pollutant combinations to be selected for the specific livestock activity, while Accessories can support meteorological measurements and deployment.
PM measurements characterise particle levels but do not by themselves identify or quantify biological bioaerosols.
Why is ammonia such an important parameter around intensive livestock facilities?
Ammonia is closely linked to nitrogen excreted in manure and urine and can be released from animal housing, manure handling and storage.
Concentrations and emissions can vary with livestock type, ventilation, temperature, manure-management practices and other operating conditions.
Continuous ambient NH₃ monitoring can therefore help operators observe temporal and spatial patterns around the farm and compare changing conditions with activities and meteorology.
It should not, however, be interpreted as a direct measurement of total farm ammonia emissions.
Where should air quality monitors be positioned around a livestock facility?
Monitoring points should be chosen according to the questions the network needs to answer.
Relevant locations can include areas near animal houses and ventilation outlets, manure or slurry storage, feed-handling areas, the farm boundary and locations toward nearby sensitive receptors.
Upwind or background measurements and downwind locations can improve interpretation, particularly when wind direction changes. For this reason, meteorological data should normally be considered as part of network design rather than placing nodes at equal distances around the farm.
Aernode Accessories include meteorological and deployment options that can support distributed farm monitoring networks.
Can continuous monitoring help investigate odour complaints from a livestock farm?
Yes. Time-resolved measurements can be compared with wind direction, manure handling, ventilation conditions, animal-house activity and complaint timestamps to provide additional context when an odour episode is reported.
Ammonia, H₂S and VOC indicators can support an investigation, but odour is a complex mixture and these measurements do not directly measure odour concentration or prove the source of a complaint.
Aernode Cloud and Reporting Tools can help maintain the historical record needed for event review, recurring-pattern analysis and documented follow-up.
Can continuous monitoring help evaluate ventilation, manure-management or other mitigation measures?
Yes. Consistent monitoring can support before-and-after comparisons when operators change ventilation settings, manure-removal practices, storage arrangements, feed or bedding management, air-treatment systems or other measures intended to reduce local impacts.
Interpretation should account for meteorology, livestock numbers, production cycle and other operating changes that can influence measured concentrations.
The resulting dataset is useful for operational review and trend analysis, but it does not by itself certify the regulatory performance of a mitigation technique.
Aernode Reporting Tools can support historical comparisons and structured reporting across different operating periods.
Can Aernode monitoring replace regulatory ammonia assessments or permit monitoring?
No. Aernode is intended for continuous indicative and supplementary ambient monitoring.
Regulatory assessments for intensive livestock installations may require emission factors, standardised measurements, dispersion modelling, specific BAT monitoring or other methods defined by the competent authority.
A distributed Aernode network adds a different layer of information: continuous local concentration data around relevant farm areas, boundaries and receptors.
It can complement formal assessments by providing operational context and a persistent environmental record, but it should not be presented as a substitute for permit requirements.
Is outdoor farm air quality monitoring the same as monitoring air inside animal houses?
No. The Aernode use case on this page is primarily outdoor environmental monitoring around livestock buildings, ventilation outlets, manure areas, farm boundaries and nearby receptors.
Indoor barn or animal-house monitoring has different objectives, including animal welfare and worker exposure, and may require dedicated instruments, sampling locations and assessment criteria.
An outdoor Aernode station can be positioned near relevant building exhausts, but it should not be presented as a replacement for dedicated indoor monitoring.
