In one example, when the user is seated, the user presses down on the weight of the signal feedback chair 100 to turn the signal back on the switch of the chair 100. However, in another example, when the user is seated, the switch of the chair 100 can be additionally returned by manually turning on the signal (not shown). After the switch of the signal feedback chair 1 is turned on, the pressure sensor 120 can sense the first pressure value when the user is seated. Generally, the first pressure value is similar to the user's weight, and the user presses down. After the weight-on signal is fed back to the switch of the chair 1 ,, the pressure sensor 12 〇 and the control circuit board 130 are in a conductive state, and the piezoelectric element 131 of the control circuit board 13 测量 is measured after the first pressure value is measured. The first electronic signal is used, and the comparison circuit 133 also sets the first electronic signal to a preset value. When the user is seated, the control circuit board 130 and the warning device 14 are in a state of power failure 200940000, but in another example, when the user is away from the seat, the pressure device no senses the second when the user is away from the seat. After the pressure value, the piezoelectric read 131 of the control circuit board 130 converts the measured second pressure value into the second electronic signal ', and the comparison switch 133 of the control circuit board 13G performs the second electronic signal with the preset value. Comparison. When the second electronic signal is different from the preset material, the control circuit board 130 activates the warning device 14 and causes it to generate an intermittent or continuous warning signal, such as a sound, a flash, a vibration, or any group thereof (4) (4) 'to the user The status of the seat is notified to the user or other person: © The description of the difference between the second electronic signal and the preset value means that the second electronic signal is compared with the first electronic signal, and the difference between the two exceeds the control circuit. The preset difference range of the board 130 may exceed the difference range set by the user or others. In other words, the user or other person can use the input device (not shown) to set a separate type or a combination of various warning conditions according to the actual needs of the user, so as to obtain a personalized better warning state. For example, the user or other person can set the weight change to be outside the -fix range (for example, if the weight change is more than 丄 kg to 8 kg 〇 〇 or more, it is considered to be changed. Or, the user or other person can also If the number of times of weight change under the fixed time exceeds m square (for example, the weight change exceeds 2 times within 5 seconds), the control circuit board 13 starts the warning device to generate a warning (4). In addition, the user or other The person can further set the warning signal to be intermittent or continuous for a period of time (for example, buzzer for 5 seconds) until the user is seated again, so that the pressure sensor 120 re-sensing the first pressure value. After that, the signal feedback device 100 is restarted to restart the pressure sensor 12 and the control circuit board to return to the conductive state 'and stop the warning signal. However, it is necessary to declare that the above example 11 200940000 kinds of warning conditions ( For example, the range in which the weight change is exceeded, the number of times the weight is changed within a certain period of time, and the duration of the warning signal are merely illustrative of the application of the present invention, and are not intended to limit the present invention.
