Generally a dimmer is controlled by a control unit that sends signal to it, thus a WiFi dimmer switch means the dimmer can be controlled by WiFi signal that sent out by mobile devices such as mobile phones and tablets and the WiFi signal is usually sent out by an lighting control APP.
The WiFi dimmer switch system shall consist of several parts, a dimmer with built-in radio frequency receiver, a WiFi to RF converter that is able to receive WiFi signal and convert it to RF signal and send to the dimmer, a router for home network and a mobile device with a lighting control APP installed. The converter shall have RJ45 port that can be connected to the router and added to the home network. And the mobile device shall be added to the home network through the router.
The APP shall be paired with the dimmer once all parts are connected well, and you should connect all these devices properly according to the user manuals. The APP sends out WiFi signal to the converter which will convert to RF signal and sends it out to the dimmer, then the dimmer will receive the RF signal and output PWM signal the connected lights. If the dimmer is DC version, you need a power supply. The WiFi to RF converter shall be connected with your router by a RJ45 cable, and a power supply is required for it depending on its input voltage. A good APP has easy and simple control interface and detailed operation instructions.
A WiFi LED dimmer enables full touch control and smooth dimming and switching functions. It is portable in your pocket and enables wireless remote control. It is smart control that enables you to control multiple zones (areas) separately or synchronously, for instance, sitting room, bedroom, bathroom, kitchen and so on, you can control them anywhere within your house. Thanks to the great PWM control of the receiver, the brightness can be adjustable smoothly without any flickering and switching on/off can be gradually instead of suddenly switching on/off that may hurt your eyes. One mobile device can control multiple receivers and each receiver maximally can be controlled by 8 remotes. Many other features like memory function that stored your preferred brightness, and operation return function are available.
It sounds a little bit difficult for a new user, but the user manual and operation instructions facilitate a lot. The final experience is great, a brand new smart home will present to you.
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.
