设计原理：Design principle:
本电路采用微波感应原理实现，任何波都有反射的特性，当一定频率的波碰到阻挡物的时候，就会有一部分的波被反射回来，如果阻挡物是静止的，反射波的波长就是恒定的，如果阻挡物是向波源运动，反射波的波长就比波源的波长来得短，如果阻挡物是向远离波源的方向运动，反射波的波长就比波源的波长来的长，波长的变化，就意味着频率的变化，微波感应正是通过反射波的变化知道有运动物体逼近或远离的。This circuit is realized by the principle of microwave induction. Any wave has the characteristic of reflection. When a wave of a certain frequency hits an obstacle, part of the wave will be reflected back. If the obstacle is stationary, the wavelength of the reflected wave is Constant, if the barrier is moving towards the wave source, the wavelength of the reflected wave is shorter than the wavelength of the wave source, if the barrier is moving away from the wave source, the wavelength of the reflected wave is longer than the wavelength of the wave source, the change of wavelength , which means the change of the frequency, the microwave induction knows that there is a moving object approaching or moving away through the change of the reflected wave.

电源通电后由Q4，Z1组成的稳压电路提供5V电源供高频三极管Q1及S型天线板工作，由其组成的天线发射电路向空间发射恒定的微波信号(频率约2.4G)，当有人或物体靠近时恒定的波形受到反射波形改变，集成电路U2将此信号通过放大比较后从其2脚输出一个5V的高电平，5V高电平驱动开关三极管Q3，Q3导通后由U1恒流IC及T1高频变压器输出的恒流电流从Q3CE极流出LED灯亮，U2有信号延时功能信号受到触发后的一个周期内(如无重复触发)5V高电平输出20秒，如果一个周期内只触发了一次则芯片延时20秒后自动关断2脚的输出高电平信号，从而切断流过Q3的电流LED灯灭，如波形受到重复触发则延时时间累积，至到没信号时延时结束灯灭。After the power supply is powered on, the voltage stabilizing circuit composed of Q4 and Z1 provides 5V power supply for the high-frequency triode Q1 and the S-shaped antenna board to work. The antenna transmitting circuit composed of it transmits a constant microwave signal (frequency about 2.4G) to the space. When someone Or when the object approaches, the constant waveform is changed by the reflected waveform. The integrated circuit U2 outputs a 5V high level from its pin 2 after amplifying and comparing this signal. The 5V high level drives the switching transistor Q3. The constant current output by IC and T1 high-frequency transformer flows out from the Q3CE pole, and the LED light is on. U2 has a signal delay function. Within one cycle after the signal is triggered (if there is no repeated trigger), 5V high-level output is 20 seconds. If a cycle If it is only triggered once, the chip will automatically turn off the output high-level signal of pin 2 after a delay of 20 seconds, thereby cutting off the current flowing through Q3 and the LED light will be off. If the waveform is triggered repeatedly, the delay time will accumulate until there is no signal The light goes off when the time delay is over.
