Source: InternetPublisher:蓝猫淘气 Keywords: 555 circuit mosquito repellent Updated: 2020/09/27
As shown in the figure is a field mosquito repellent circuit diagram with an oscillation frequency of about 22KHz. The oscillation frequency synthesized by the 555 on the left is about 22KHz, and then the 555 monostable circuit on the right generates a 50Hz square wave with a duty cycle of 50% and is input to the 555 on the left. 5 feet, synthesize a kind of noise, used to repel mosquitoes.
