ROI Calculation Logic

Assuming conventional sensor installation costs $2K/unit and annual maintenance $350/year (AI est.). This technology could reduce installation to $650/unit and maintenance to $150/year (AI est.) due to fewer components. For a company deploying 50 sensors annually, this translates to ($2K - $650) × 50 units + ($350 - $150) × 50 units = ~$67.5K + ~$10K = ~$77.5K in direct savings. Additionally, a 5% reduction in defect rates could avoid ~$25K (AI est.) in economic losses (based on $500K annual production), totaling ~$100K/year (AI est.) in cost reduction.
