COMPACT, PORTABLE AMMONIA SENSORS FOR ANIMAL HEALTH AND WELL-BEING

Objective

The major goal is to develop and commercialize aerospace-caliber, portable absorption spectroscopy sensors for continuous ammonia measurements with accuracy of <1 ppm. The final commercial product sale price will be 10x - 50x less than current commercial sensors for wide adoption into poultry farms worldwide.To achieve this goal, the combined team will:1. Understand the Operating Environment: Gain a comprehensive understanding of the sensor systems' operating environment in poultry settings (e.g., dust environment, fluctuating environmental conditions, accessibility etc.)2. Optimize Sensor Design: Design low-cost compact TDLAS ammonia sensor system for building and delivering during the Phase-II research effort.3. Demonstration Measurements: Perform preliminary measurements of ammonia using laser absorption spectroscopy and validate its sensitivity and accuracy.4. Complete Design of Sensor Architectures for Phase II: Design and develop the full sensor architecture to be built in Phase II. Develop the necessary software packages to quickly and automatically post-process the absorption spectroscopic data into ammonia concentrations.
