Meanwhile dark room at night , people go to the dark lamp switch and it is particularly difficult, and may even be dangerous. With intelligent lamp, these problems will be solved. Intelligent lamp can do automatic light off, automatically adjust brightness. When the ambient light is dark to a certain extent , and the presence of people around when the lamp will automatically turn on and automatically adjust the LED luminous intensity depending on the environment , thus protecting the user39。s eyesight . When the user leaves , or when the ambient light is strong enough , lamp will automatically turn off to reduce power consumption and extend lamp life. The project uses intelligent lamp produced STC12C5A60S2 STC microcontroller as the core processing system, using RE200B pyroelectric infrared sensor bined with human BISS0001 pyroelectric infrared processing chip , constitute human infrared sensor module can react to body heat near infrared signals feedback signal to the microcontroller processing 。 photosensitive resistance as light sensors , the role is to collect ambient light signal, the feedback to the microcontroller different analog voltage value by STC12 series MCU internal builtin a / D conversion MCU judgment on the strength of the ambient light to further adjust the LED lightemitting diode control PWM duty cycle, adjusting lamp luminous intensity.
