Automatic notification of out-of-stock just by placing items - Inventory management IoT with weight sensor × ESP32.
We are developing our own product "sphere-weight," which automatically measures the remaining stock daily by simply placing the inventory container on a weight sensor platform and notifies stockouts via email or Web API. We will introduce the technology configuration of load cell × ESP32 and battery operation, the current status of the PoC, a roadmap for centralized management of inventory and orders including automatic ordering, dashboards, traceability, and demand forecasting, as well as plans for product commercialization through crowdfunding.
