Abstract
An inventory management device to measure usage of sheets in a roll has been described. The inventory management device includes a resistive sensor in physical communication with a sheet in the roll that measures a resistance value between the resistive sensor and the sheet. The inventory management device includes a vibration sensor in electronic communication with the resistive sensor to generate a vibration signal that corresponds to a vibration of the roll. The inventory management device includes a storage unit in electronic communication with the resistive sensor to store the resistance value. The inventory management also includes a controller in electronic communication with the resistive sensor and storage unit to measure a change in the resistance value.

An inventory management device to measure usage of number of sheets in a roll, the inventory management device comprising:
- a resistive sensor in physical communication with a sheet in the roll that measures a resistance value between the resistive sensor and the sheet;
- a vibration sensor in electronic communication with the resistive sensor to generate a vibration signal that corresponds to vibration of the roll;
- a storage unit in electronic communication with the resistive sensor to store the resistance value;
- a controller in electronic communication with the resistive sensor and storage unit to measure a change in the resistance value;
- a transmitter in electronic communication with the controller to autonomously transmit an output signal when the controller measures the change in the resistance value;
- and
