ZigBee is a wireless communication protocol based on radio frequency. It is widely used for home automation and internet of things. It enables to control home devices including light switch, blind, door lock, smoke detector, thermostats and many more.
A ZigBee system shall consist of three parts: coordinators (gateway), routers and end devices. A coordinator or gateway is responsible for forming ZigBee network or bridging to other networks and adding routers and end devices to the network or remove them from the network. As well as running an application function, a router can act as an intermediate router, passing on data from other devices. A router can start operation only when it has establishes connection with coordinator. End device contains just enough functionality to talk to the parent node (either the coordinator or a router); it cannot relay data from other devices. This relationship allows the node to be asleep a significant amount of the time thereby giving long battery life.
ZigBee light switch is ZigBee Pro enabled end device which can be added to the network by coordinator or gateway from APP interface on smart phone or PC interface. Once added, the light dimmer switch can be controlled directly from gateway APP interface. ZigBee remotes are also end devices that can be added to the network and bind the light switch so from APP interface so that it can control the light switch. Each network can contain up to 65000 devices. ZigBee is a low cost wireless solution incorporates power saving mechanisms for all device classes, plus support for battery-less devices.
ZigBee gateway supports group control, which means you can add the dimmer switches to different groups and control them separately from APP interface or you can bind them with ZigBee Group control remotes and control separately. Lamps in different areas of your house can be added to different groups for flexible and smart control. ZigBee gateway also supports scene control which enables you to recall different light intensity levels for each area of your house.
A great feature of ZigBee is that it enables cloud control while the gateway is configured to connect to Ethernet. You can monitor and control your home lighting on internet even if you’re thousands of miles away from your home.
3D Moon Lamp for Creating Right Atmospheres
Lighting is a very important aspect for creating right atmospheres for dating, parties and holidays. Compared to traditional lighting design, 3D Moon Lamp is a more flexible and portable LED moon lamp that adopts LED light source and is powered by rechargeable battery.
FDM 3D Printer Widely Used for Prototyping and Concept Model Building
Fused Deposition Modeling builds concept models, functional prototypes and end-use parts in standard, engineering-grade and high-performance thermoplastics. It’s the only professional 3D printing technology that uses production-grade thermoplastics, so parts are unrivaled in mechanical, thermal and chemical strength.
DLP 3D Printer To Print High Precision Objects With Ultra Smooth Surface
DLP stands for digital light processing that is one of the popular technologies used for 3D printing. Unlike FDM technology, this technology uses light from projectors to turn liquid resin into a solid object, one layer at a time and accumulates layer by layer finally to form an object.
