Rectifier circuit and filter circuit
In electronic circuits, most of them require a DC regulated power supply for driving. For example, in the amplifying circuit, on the one hand, the DC voltage regulator must establish a suitable static operating point for the circuit operation, and on the other hand, it must provide the required energy for the amplification of the signal.
Description of several common industrial control signals
In industrial automation control, various concepts such as switch quantity, digital quantity, analog quantity, discrete quantity, and pulse quantity are often encountered, and people are easily confused with these concepts in practical applications. The various concepts are listed as follows
Detailed explanation of LoRa wireless transceiver communication technology
LoRa is a LPWAN communication technology, which is widely used in ultra-long-distance wireless transmission scenarios based on spread spectrum technology.
The application prospect of Lora module in the field of intelligent meter reading and agricultural informatization
LoRa technology occupies an important position in the development of the Internet of Things. Because of its ease of construction and deployment, it has become a commonly used Internet of Things dedicated network communication technology. In recent years, due to the maturity of LoRa technology in the leading position, as well as the characteristics of long transmission distance, low power consumption and strong anti-interference, LoRa modules are widely used.
What is the reason that cloud computing is the cornerstone of IoT development
As the Internet of Things continues to mature and develop, cloud computing has gradually become an indispensable part of it. The Internet of Things collects a large amount of data that is difficult to calculate through a large number of sensors, and cloud computing can intelligently carry out these collected data. processing. Cloud computing is the cornerstone of the development of the Internet of Things, and the Internet of Things is the largest user of cloud computing.
