Development of a decision tool to evaluate NH3 concentration in pig houses

Ammonia concentration must remain below 20 ppm for both animal welfare and the quality of farmers’ working conditions.
Portable sensors exist and are widely used in industry to alert operators when critical thresholds are exceeded. These sensors are affordable and easy to use. However, their use in livestock buildings shows certain limitations, particularly due to high particle concentrations combined with elevated humidity. Regular and therefore costly calibration is required. To address this challenge, a decision support tool called Sim’Ammo has been developed.
