In some embodiments, the pressure sensor can also be provided at the electronic tag, and the pressure signal is generated by pressing the pressure sensor.

[0026] In another embodiment of the present invention, the trigger data also includes a gesture trigger signal; the medicine storage area is provided with a gesture recognition area, and a gesture trigger signal is generated by performing a preset trigger gesture in the gesture recognition area; the preset trigger condition includes the generation of a gesture trigger signal. In this embodiment, a plurality of infrared sensing sensors are provided in the gesture recognition area, and the user completes the preset trigger gesture by passing his hands through the plurality of infrared sensing sensors along a preset path, and a gesture trigger signal is generated after completing the trigger gesture. In some embodiments, the gesture recognition area includes two infrared sensing sensors, and the two infrared sensing sensors are provided on both sides of the electronic tag. The two sides of the electronic tag include the left and right sides of the electronic tag and the upper and lower sides of the electronic tag.

When the medicines are placed or taken out of the storage area, the weight data stabilizes to another constant value after a period of continuous change. The part of the weight change curve where the weight data stabilizes after continuous change is marked as a weight fluctuation event. The difference between the two constant values ​​before and after the weight fluctuation event is the weight difference. The different weight differences before and after each fluctuation time indicate that the amount of medicines taken by the user each time is different.
