Comfortable environment providing apparatus

1. A comfortable environment providing apparatus that controls at least one comfortable environment creation device to provide a user with a comfortable environment, the comfortable environment providing apparatus comprising:

a monitor main unit having first and second connection structures and attached to a user wearable band;

a plurality of sensor units attached to the user wearable band, each monitoring a condition related to the user and outputting detection data representing the monitored condition of the user to the monitor main unit when carried by the user, at least one of the plurality of sensor units monitoring a physical state of the user as the condition related to the user, wherein each sensor unit includes first and second connectors electrically connectable to the monitor main unit or another one of the sensor units, the first connectors of the plurality of sensor units having the same structure, the second connectors of the plurality of sensor units and the first and second connection structures of the monitor main unit having the same structure, and wherein the plurality of sensor units and the monitor main unit that are attached to the same user wearable band are connected in series along the user wearable band; and

a control circuit for executing control of the at least one comfortable environment creation device so that the detection data approaches comfortable environment reference data quantitatively or numerically indicating a comfortable environment.

2. The comfortable environment providing apparatus according to claim 1 , further comprising a storage device storing the comfortable environment reference data, wherein:

the comfortable environment reference data includes data corresponding to a condition that does not have to be improved; and

the control circuit determines from the detection data of at least one of the sensor units whether or not the monitored condition should be improved and executes the control of the at least one comfortable environment creation device so that the detection data approaches the comfortable environment reference data.

3. The comfortable environment providing apparatus according to claim 2 , wherein after starting to execute control of at least one comfortable environment creation device and when determining from updated detection data of a most recent detection of at least one of the sensor units that a most recently monitored condition no longer has to be improved, the control circuit ends execution of the control and executes a new control of the at least one comfortable environment creation device so as to maintain the comfortable environment.

4. The comfortable environment providing apparatus according to claim 1 , further comprising:

a storage device for storing condition data indicating a specific condition predicted beforehand in association with control content data indicating content of the control executed on the at least one comfortable environment creation device to create a comfortable environment in accordance with the specific condition;

wherein the control circuit executes control of the at least one comfortable environment creation device in accordance with the control content data when the detection data matches the condition data.

5. The comfortable environment providing apparatus according to claim 1 , further comprising:

an informing device for informing the user of the content of the control executed on the at least one comfortable environment creation device by the control circuit.

6. The comfortable environment providing apparatus according to claim 5 , wherein:

the informing device announces the content of the control to the user before starting execution of the control of the at least on comfortable environment creation device; and

the control circuit starts execution of the control of the at least one comfortable creation device after the announcement.

7. The comfortable environment providing apparatus according to claim 5 , wherein:

the informing device outputs a message describing at least one of the monitored conditions and announces the content of the control before starting execution of the control of the at least one comfortable environment creation device; and

the control circuit starts execution of the control of the at least one comfortable environment creation device after the output of the message describing the at least one of the monitored conditions and the announcement of the content of the control.

8. The comfortable environment providing apparatus according to claim 5 , wherein:

the informing device outputs a confirmation message confirming whether or not to execute the control of the at least one comfortable environment creation device in accordance with the content of the control; and

the control circuit starts execution of the control of the at least one comfortable environment creation device when receiving an affirmative response to the confirmation message.

9. The comfortable environment providing apparatus according to claim 1 , further comprising:

a storage device for storing a first comfort level for at least one of the monitored conditions and a second comfort level that is higher than the first comfort level in association with the first comfort level;

wherein when determining that the most recent detection data of the sensor unit monitoring the monitored condition reaches the first comfort level, the control circuit executes control of the at least one comfortable environment creation device so that subsequently detection data of the sensor unit approaches the second comfort level.

10. The comfortable environment providing apparatus according to claim 1 , wherein the control circuit generates a control signal for decreasing the difference between the comfortable environment reference data and the detection data and provides the control signal to the at least one comfortable environment creation device.
