带定时关闭功能的自动夜灯Automatic Evening Light With Cut-Off Timer
➀ 该项目利用LM358运算放大器和光敏电阻设计电路，实现黄昏自动开灯并在2-6小时后关闭，减少能源浪费；
➁ 通过超级电容实现定时功能，电位器可调节光照灵敏度与关闭时间，模拟人员活动以增强安防效果；
➂ 提供PCB布局方案与校准教程，支持无人值守运行，适用于家庭户外照明或长期空置场所。
➀ A DIY circuit using an LM358 op-amp and light-dependent resistor (LDR) automatically switches on lights at dusk and turns them off after 2–6 hours, reducing energy waste.
➁ The system employs a super capacitor for timing control, adjustable via potentiometers to set light sensitivity and shut-off duration, mimicking human presence for security.
➂ Includes PCB design guidelines, calibration steps, and operates independently without manual reset, ideal for unattended homes or outdoor lighting.
