Abstract: Utilizing the techniques disclosed herein, sensor data inaccuracies may be corrected such that calculated fill levels more accurately reflect the actual fill level of the item within an automatic replenishment device (ARD). For example, the ARD may include a sensor configured to collect the sensor data (e.g., a distance between the sensor and an item contained within the ARD). Sensor data associated with an item within the ARD may be received. A measurement offset value specific to the item may be identified. An estimated fill level of the item within the ARD may be calculated based at least in part on the distance measured between the sensor and the item and the measurement offset value specific to the item.
