Walmart is deploying millions of battery-free ambient IoT sensors across its U.S. supply chain by 2026, partnering with Wiliot for enhanced, real-time inventory visibility. This initiative utilizes ambient energy to power sensors tracking temperature, location, and humidity, feeding data into Walmart’s AI to optimize supply chain efficiency and ensure inventory accuracy. The rollout includes Supercenters, Neighborhood Markets, and distribution centers, aiming for improved decision-making, reduced manual labor, and enhanced customer experience through better product availability.
