With the development and changes of the social economic structure, family population structure and information technology, and the improvement of human requirements for the safety, comfort and efficiency of the home environment, the demand for smart homes has greatly increased, while more and more families require Smart home products must not only meet some basic needs, but also require smart home systems to be simple, convenient, and safe in terms of function expansion, extension, and even service.
Introduction of technology used in smart home systems
The smart curtain system is an integral part of the smart home system, so its technology is also the same as the smart home system. Although the concept of smart home has been around for a long time and the market demand has always existed, the development of smart home has not been widely applied due to the breakthrough of related technologies for a long time. The smart home technologies currently in the market are introduced as follows:
1 ) Wired mode In this way, all the control signals must be connected by wire, and the signal lines on the controller side are scary, but it is also very difficult to troubleshoot problems. The shortcomings of the wired method are very prominent, complicated wiring, heavy workload, high cost, difficult maintenance, and difficult to network. These shortcomings ultimately lead to the wired smart home only staying in the concept and pilot stage, and cannot be promoted on a large scale.
2 ) The wireless system used in the smart home wireless system needs to meet several characteristics: low power consumption, stability, easy expansion and grid connection; as for the transmission speed, it is obviously not the focus of such applications. Several wireless methods currently available for smart homes
Bluetooth: It is a radio technology that supports short-range communication of devices (generally within 10m). This technical communication distance is too short, and it is also a point-to-point communication method, which is not suitable for the requirements of smart homes.
Wi-Fi : In fact, it is another name for IEEE 802.11b. Its biggest feature is that it is convenient for people to access the Internet anytime, anywhere. However, the disadvantages for smart home applications are obvious, with high power consumption and strong networking expertise. High power consumption is a very fatal flaw for deploying low-power sensors anytime, anywhere, so although Wi-Fi is very popular, it only plays a supplementary role in smart home applications.
Zigbee : The foundation of Zigbee is IEEE802.15. But IEEE only deals with low-level MAC layer and physical layer protocols, so the Zigbee Alliance expanded IEEE to standardize its network layer protocols and APIs. Zigbee is an emerging short-range, low-rate, low-power wireless network technology, mainly used for short-range wireless connections. It has the characteristics of low complexity, low power consumption, low speed, low cost, ad hoc network, high reliability, and over-the-horizon. It is mainly suitable for application in fields such as automatic control and remote control, and can be embedded in various devices. In short, Zigbee is a cheap, low-power, self-organizing short-range wireless communication technology, these characteristics conform to the requirements and trends of the Internet of Things development. At present, the application of the Internet of Things and Zigbee technology in smart homes, industrial monitoring and health care are highly integrated.
Sub-GHz ( 315M / 433M / 868M / 915M ): These wireless radio frequency technologies are widely used in vehicle monitoring, remote control, telemetry, small wireless networks, identification, non-contact RF and other places, but due to their weak anti-interference ability, networking Inconvenience, general reliability, the application effect in the smart home is very good.

·Basic precautions
Do not put expensive oil into low-quality cartridges to avoid wastage. Most pre-filled oil cartridges have the so-called 510 thread. The oil cartridge screws onto a rechargeable battery. Some of these batteries have buttons and some heat up automatically when you pump the oil. Some batteries have multiple temperature settings and some heat up to a preset temperature; these features need to be known in advance.
·Cleaning notes
Use a suitable cleaning tool to clean them, such as activated charcoal or dried tea leaves in a used pipe to absorb the oil. It is important not to use alcohol or other boiling water to clean the pipe, and to wait until it has cooled down completely before cleaning. Otherwise, the hot stem will come into contact with the watery liquid and cause the mouthpiece tenon to loosen, thus shortening the life of the 510 cartridges.
This is what you should be aware of when using 510 cartridges. At the same time, when using 510 cartridges, there are still some vaping tips, for example, when using them, be careful not to suck too hard, will not produce smoke. When you inhale too hard, the smoke is sucked directly into your mouth and not atomized by the atomizer, so gently inhaling is more powerful and gives you a better vaping experience.
