Smart farm monitors methane (CH₄) and other greenhouse gases emitted by farm animals (e.g. cattle and sheep) through laser gas sensing technology to quantify the environmental impact of farming and provide a scientific basis for optimizing feed formulations and emission reduction measures. In addition, the technology can monitor air quality in pastures to ensure animal health and productivity.

1. Farm Methane Emission Monitoring: Laser gas sensors are arranged in the farms to continuously record methane emissions, and analyze them comprehensively in combination with the number of animals and the type of feed.

2. Air Quality Monitoring: Detecting changes in ammonia concentration in the pasture, identifying the risk of environmental deterioration and linking ventilation equipment for control.

3. Individual Monitoring: Portable laser sensing devices are used to assess the methane concentration in the breath of individual animals, helping to optimize feed formulation to reduce emissions.

Traditional Methods: Manual sampling combined with chemical analysis is inefficient and does not reflect the dynamics of emissions.

Laser Sensing Advantages:

• Real-Time Monitoring and High Accuracy: Dynamically captures changes in methane and ammonia concentrations

• Wide Area Coverage: Can monitor a wide range of pasture areas and support intelligent management

• Data Analysis Support: Combining feed optimization and emission reduction measures to improve production efficiency
