## Abstract

This cover 10 is mounted in a body having a heating unit that heats a base material containing an aerosol source, the cover comprising: an external sensor 31 that detects external information, which is separate from internal information related to the state of the body and internal information related to the state of the cover; a display unit 80 that displays information; and a display control unit 62 that causes the display unit 80 to display the external information detected by the external sensor 31 and/or information acquired from an external device other than the cover 10.

## Claims

### Claim 1

A cover attachable to a body including a heater that heats a substrate containing an aerosol source, the cover comprising:
a sensor that detects external information other than internal information related to a state of the body and internal information related to a state of the cover;
a display that displays information; and
a display controller that causes the display to display at least the external information detected by the sensor or information acquired from an external device other than the cover.

### Claim 2 (depends on 1)

The cover according to claim 1, further comprising:
a plurality of connectors connectable to the body,
wherein the display is provided between the plurality of connectors, and
wherein the sensor is provided at one of ends in a centerline direction of a column-shaped holder formed in the body to accommodate a portion of the substrate.

### Claim 3 (depends on 2)

The cover according to claim 2, wherein the sensor is closer to an opening of the holder than the plurality of connectors in the centerline direction.

### Claim 4 (depends on 1)

The cover according to claim 1, further comprising:
a memory that stores a control sequence specifying a temporal change in a target temperature of the heater during heating of the heater,
wherein the display controller causes the display to display information related to the control sequence stored in the memory.

### Claim 5 (depends on 4)

The cover according to claim 4, wherein the memory stores a plurality of control sequences, and
wherein one control sequence is selectable from the plurality of control sequences displayed by the display.

### Claim 6 (depends on 1)

The cover according to claim 1, wherein the sensor detects a temperature or a humidity, and
wherein the display controller causes the display to display a notification that a temperature or a humidity is suitable for storage of the substrate based on at least the temperature or the humidity detected by the sensor, or a temperature or a humidity acquired from the external device.

### Claim 7 (depends on 1)

The cover according to claim 1, wherein the sensor detects a heart rate or a pulse rate, and
wherein the display controller causes the display to display a warning when the heart rate or the pulse rate detected by the sensor is outside a predetermined range.

### Claim 8 (depends on 1)

An aerosol generation device comprising:
a body including a heater that heats a substrate containing an aerosol source; and
the cover according to claim 1 attached to the body.
