The indicator LED4 does not emit light; the lack of alarm resets one end of the switch SW2 to the system ground, the other end is connected to the +5V system power supply, and the other is connected to the 3 pin of the MCU microprocessor U7. This embodiment uses the method of setting the time to achieve this. If the water in the basin is set to exceed 15 days, it is considered to be lack of nutrition. The 18-pin output of the MCU microprocessor U7 outputs a low-level signal, and the lack of alarm indicator LED4 emits light, indicating the lack of alarm information, and the same MCU microprocessor U7 The 11, 12-pin output is low, and the music module U3 drives the speaker SP to sound an alarm.

[39] After receiving the alarm message, the user presses the lack of alarm to reset the switch SW2 and supplement the nutrition. In the absence of the alarm, the reset switch SW2 is pressed, the MCU microprocessor U7 detects that the 3 pin I has a low-level pulse input 吋, cancels the alarm message, resets the meter, and starts the next counting cycle, the system recovers. normal. When the power is off, the day is automatically held in the day memory U6, and the data is not lost.
