The Internet of Things is a complex application technology, which covers a wide range. It not only covers microwave technology and electromagnetic theory, but also involves the principle of infinite communication and semiconductor integrated circuit technology. It is a multidisciplinary integration. Emerging application technologies. In the application of wireless communication principles, there is a crystal oscillator that is more important, that is, a 3.2*2.5 size 24Mhz quartz crystal resonator, whose main function is to transmit and receive frequency signals. Therefore, it is the first opportunity for quartz crystal oscillators. With the development of the Internet of Things, quartz crystal oscillators have also become popular products.
