With the development of cities, people’s living standards are gradually improving, and most families are equipped with cars. But when it comes to parking, especially in big cities, we have to talk about the difficulty of parking. Because of the gradual fermentation of the parking problem, smart parking was born out of luck. The development potential of smart parking is … Continua a leggere
Whether the urban lighting project is well done or not, there are several key information, such as reflecting urban art,WiFi Wireless Module humanistic characteristics and so on. However, if each place blindly pursues independent characteristics, it will only make the city night scene more varied and unable to reflect humanistic feelings. The implementation of a city’s lighting project is closely … Continua a leggere
The integrated op amp is a multi-stage circuit with extremely complex interior. Usually, in circuit design, we only need to master the relevant characteristics of the integrated op amp. DC-DC isolation type The specific internal circuit does not need to be overly considered. To learn and understand the characteristics of the integrated op amp, we can pass Analysis of some … Continua a leggere
