As the most attractive new generati

As the most attractive new generation light source in the world, LED is known as the most promising green light source in the 21st century because of its high brightness, low heat, long life, non-toxic, recyclable and other advantages. Therefore, in the face of the development of this new technology, we should pay more attention to the further development of this technology, so that led lights can truly enter every family, to achieve the reduction of resource and energy consumption. With the rapid development of electronic technology and electronic devices, more and more intelligent and humanized modules have been designed, produced and used, such as pyroelectric infrared sensor, photosensitive module, etc. And people are more and more adept at the application of PWM wave and PID control algorithm. The research and development of this system is to further improve the intelligent lighting system, and achieve the effect of integrating intelligence and green energy saving.
