New energy includes hydropower, wind energy, solar energy and so on. Although wind power or water power are cheaper, most home users are not likely to find suitable venues for erection and high erection costs. Solar energy is different. Any user who owns a home can only use a solar panel as an auxiliary energy source if he finds a window that is exposed to sunlight. A few hundred yuan investment can be set up.

Buzzer alarm circuit

The alarm circuit uses a buzzer to issue an alarm sound. Since the driving ability of the STC89C52 output pin is weak, the buzzer must be driven with a triode. During the real-time monitoring of the battery voltage, once the detected voltage value continuously exceeds the threshold range, it starts its own alarm circuit. That is, when the voltage exceeds the programmed maximum or minimum value, the P2.6 pin (beep) The end) outputs a low level and the transistor turns on, driving the buzzer to send an alarm signal.
