Smart Agro-Livestock Infrastructure: Full-Scenario Gas Monitoring Solutions

As modern agriculture transitions from traditional methods to regionalized, large-scale, and intelligent operations, environmental control has become a key factor in determining the quality and economic value of plant and animal growth. In large-scale livestock farms or off-season vegetable and fruit greenhouses, even minor fluctuations in air composition can trigger chain reactions—from respiratory diseases in livestock to reduced crop yield.

As a global leader in gas sensing technology, Nexisense brings industrial-grade precision detection technology to the agricultural sector. Through real-time online monitoring, temperature and humidity compensation, and automated linkage logic, we create an “invisible safety barrier” for the growth of plants and animals.

Animal Farms: From Environmental Monitoring to Increasing "Livestock Yield"

In intensive pig, poultry, or cattle farms, enclosed or semi-enclosed spaces easily accumulate harmful gases, primarily from anaerobic fermentation of waste and livestock respiration.

1. The Lethal Threat of Ammonia (NH3) and Hydrogen Sulfide (H2S)

Animal waste releases large amounts of pungent gases during decomposition. Ammonia damages eye and respiratory mucosa, lowering immunity; hydrogen sulfide, being highly toxic, can cause livestock death and threaten personnel safety.

• Solution: Deploy SGA-500 series online ammonia/H2S detectors for 24-hour monitoring, automatically activating exhaust fans when concentrations exceed thresholds.

2. Carbon Dioxide (CO2) and Oxygen (O2) Balance

High-density livestock environments can cause CO2 accumulation and relative oxygen deficiency. Livestock in long-term hypoxia exhibit poor appetite and slow growth.

• Advantage: Nexisense uses NDIR-based CO2 sensors, unaffected by humidity, providing stable and reliable data.

3. Coordinated Temperature and Humidity Control

Gas concentrations often fluctuate with temperature and humidity. Nexisense monitoring systems support three-in-one (gas+temperature+humidity) integration, providing complete data support for smart farms.

Plant Farming & Greenhouses: Precise Growth Control

Plant growth, development, ripening, and preservation require precise air composition control. Accurate gas management is key to increasing agricultural value.

1. Carbon Dioxide: Plant “Nutrition”

CO2 is essential for photosynthesis. In sunlight greenhouses, CO2 may be low in the morning; adding CO2 can significantly increase yield.

• Monitoring Logic: Use SGA-100/700 series smart modules integrated into greenhouse control systems for precise CO2 supplementation and monitoring.

2. Ethylene (C2H4): The Art of Precision Ripening

In off-season fruit ripening rooms (e.g., bananas, mangoes, tomatoes), ethylene concentration determines taste and maturity. Excess causes over-ripening; deficiency prevents desired ripeness.

• Application: SGA-500 online ethylene detectors monitor ripening room concentrations in real time, paired with automated gas valves for “one-button ripening.”

3. Hypoxia Prevention in Mushroom & Germination Experiments

In high-respiration enclosed environments like mushroom cultivation, CO2 can rise rapidly. Nexisense monitoring ensures oxygen safety for researchers entering experimental rooms.

• Comprehensive patrol: Technicians can use portable detectors to randomly inspect greenhouse blind spots and sewage outlets, ensuring no hidden risks.

Linkage Logic: Automated Smart Agriculture Loop

1. Automatic Ventilation: Ammonia > 25ppm or H2S > 10ppm triggers relay to start forced ventilation.

2. CO2 Supplementation: If CO2 is below optimal plant growth levels (e.g., 400ppm), system activates CO2 cylinder or generator for supplementation.

3. Environmental Alerts: Oxygen below 19.5% Vol triggers local audible/visual alarms and app notifications to restrict personnel entry.

FAQ

Q1: Ammonia is highly corrosive. How long can Nexisense devices last?
A1: SGA-500 series sensors feature stainless steel 316 probes and triple-protection coated PCBs. With regular cleaning, electrochemical ammonia sensors typically last 2-3 years.

Q2: Why choose NDIR sensors over electrochemical for CO2 monitoring?
A2: Greenhouses often have humidity above 90% RH. Electrochemical sensors degrade; NDIR uses optical absorption, lasts 5-10 years, and is interference-resistant.

Q3: How to position ethylene detectors in ripening rooms?
A3: Install at ~1.5 m height in the room center. For large rooms, add points near intake valves and center for uniform concentration.

Q4: Do farm detectors need a controller?
A4: Small barns can use SGA-500 relay to control fans. Medium/large farms should use SGA-800 controller for centralized data and alarm logic.

Q5: Readings do not return to zero after installation. What to do?
A5: One-button zero calibration can be performed in clean air or with nitrogen flow to ensure accurate baselines.

Q6: If a sensor fails, do we return the device to the manufacturer?
A6: No. SGA-700 modular design allows onsite sensor module replacement without rewiring or returning to factory.

Q7: How to monitor farm data remotely?
A7: Devices support RS485 (Modbus RTU). Connecting via 4G/5G data acquisition allows real-time concentration, temperature, and humidity monitoring on the Nexisense cloud platform via app or PC.

Q8: Optimal CO2 concentration for greenhouses?
A8: Typically 800-1200ppm for most vegetables. Online detectors allow high/low alarms to automate supplementation and maintain closed-loop control.

Summary

Gas monitoring is now a core infrastructure for digital transformation in modern plant and animal farming. Nexisense’s precise, corrosion-resistant, intelligent monitoring products provide scientific support for livestock health, plant yield, and agricultural safety.
