Intelligent inventory monitoring system with internet of things sensor devices, predictive analytics, and automated replenishment

A method of automated inventory monitoring, the method comprising:

• configuring operational network connectivity for a sensor device using a first communication mechanism;
• periodically generating, by a sensor of the sensor device, a fill-state signal indicative of an amount of product remaining in a container;
• transmitting telemetry including the fill-state signal to a network-accessible data processing service;
• computing an inventory level based at least in part on the fill-state signal and container configuration data;
• storing the inventory level with a timestamp;
• generating a notification when the inventory level satisfies a user-configurable threshold;
• and
• optionally associating the sensor device with a user account using a secure adoption token.

A sensor device for automated inventory monitoring, the sensor device comprising:

• a housing configured for integration with a container lid or for retrofit attachment to a third-party container;
• a processor;
• a power system;
• at least one non-contact distance ranging sensor configured to generate a fill-state signal indicative of an amount of product remaining;
• a short-range wireless interface configured for provisioning;
• and
• an operational wireless interface configured to transmit telemetry including the fill-state signal to a remote service;
• wherein the processor is configured to manage power states including a low-power sleep state and to transmit telemetry according to a scheduled interval or an event-triggered interval.
