Wireless doorbell transmission circuit design
Abstract
Along with the rapid development of radio work technology, as
well as people's living standards greatly improved the safety of the living environment to facilitate the proposed requirements, especially in the intelligent residence, a safe and reliable, use convenient wait for an advantage in one of the intelligent products are ing more and more popular, so the design of the system be wireless door bell in recent years the trend of research.
This paper mainly introduces a new wireless door bell, it not only simple structure, easy installation, concise and practical, and cost-effective. This kind of the bell has low power consumption, low the characteristics of the planning, design and low cost, the global financial crisis situation, the development of wireless the doorbell while we should research and innovate, continues to intelligent products, digital and information development direction.
The wireless the doorbell circuit with advanced pulse modulation launch and vibration frequency stability, linb03 technology, performance stability, circuit is simple, reliable, strong anti-interference, transfer of distance, circuit the advantages of small size, meet different needs of life, and has a broad development prospects.
With microelectronics technology, wireless technology development by starting a cable the bell to now wireless the doorbell, and have to intelligent digital the doorbell, visible interphone the doorbell transition, the speed of development c
