In recent years, more and more people buy smart devices.
I don’t know if the machine friend has encountered something like ZigBee smart sockets, do you know what ZigBee is?
First of all, ZigBee is not a smart home brand.
ZigBee, also known as purple bee.
It is not a kind of bee … but a wireless network protocol with low speed and short distance transmission.
ZigBee is based on the IEEE802.15.4 protocol, and each ZigBee network number pass module can communicate with each other.
You can treat it as a special “Bluetooth”, which is not very different.
The transmission range is only 10 ~ 75m, and the frequency is only 250kbit/s, 20kbit/s and 40kbit/s … super slow.
But it is these characteristics that it can achieve low power consumption
(Two quarters 5 batteries can be used for 6 to 24 months)
, Low cost and low complexity.
Because of these characteristics, it is used on a large number of smart devices.
ZigBee also has many different standards.
ZigBee Home Automation is a global standard for smart home.
ZigBee Input Device is a global standard for consumer electronics and mouse and keyboard touchpads.
ZigBee Light Link is the standard for lighting products.
ZigBee 3.0 is the IEEE 802.15.4 standard launched for the Asian market, based on 2.4GHz network.
This string of English on your socket is so complicated …
Unexpectedly!
