We touch doorbell, switch, keyboard and other micro electric objects every day. Most of them need to be connected to electricity or use batteries. In particular, the doorbell has a built-in button/No. 7 battery for power generation, which transmits wireless signals by pressing the doorbell button with fingers. Therefore, the linbellG4 self generating wireless doorbell does not need that trouble. It can generate power by pressing the doorbell button, Transmitting wireless signals, doorbell transmitters no longer need batteries. At present, there are more or less problems with doorbells in the market: 1. The doorbell on the anti-theft door sounds too low, which can only be heard at the door; 2. The ordinary wireless doorbell needs to change the battery frequently; 3. The wiring is complex and requires half a day of groping (such doorbells gradually disappear in the market); 4. The battery decays in wet weather, and the doorbell is damaged; 5. The host heats, causing equipment failure; 6. Crosstalk with neighbors leads to strange sounds. When we saw the new generation of self generating wireless doorbell linbellG4 developed and produced by LinkedIn Technology, the doorbell transmitter does not need batteries. Only through LinkedIn's core kinetic energy generation technology, the energy of each doorbell button press can be converted into electricity and send wireless signals. We were surprised. Let's have a look at this product. On the front of the unpacking box is the product logo of LinkedIn Technology and on the side of the trial sticker of our trial platform is the English name and product name of LinkedIn Technology, specifically indicating the product feature "no battery, worry free and environmental protection". On the back of the packaging box, some functional parameters of the product are unpacked, and the transmitting end and receiving end equipment and some parts are seen. Take out the receiver and see that there are two buttons on the front. They are volume and music switching. The back is the receiver plug and the audio transmitter. It is very simple. In addition to the logo, it is just a groove. It seems to tell you that pressing it doesn't mean that you don't need batteries. In fact, the thicker part of the transmitter is only 15mm, and the frame is even as low as 7.8mm. It is small and exquisite. The back is simpler. It seems that there is no content. After disassembling it, I saw a lot of snap points. I was afraid that it was too violent, so I didn't disassemble it further. I saw that other testers had disassembled it. There were many circuit boards and simple coils around. LinkedIn carefully matched 2 screws in the packing box for easy installation. At the same time, 3M double-sided adhesive tape was carefully prepared. A user guide is included with the package. Novices are not afraid to install it. Later, of course, it is our big group photo principle analysis. Since there is no battery, how can linbellG4 self generating wireless doorbell generate power? Officially, LinkedIn kinetic energy generator and Faraday's new law of electromagnetic induction are used to generate electricity by plane motion. Ultra small energy collection module perfectly replaces the battery. The internal power generation module collects the energy when pressing the doorbell and converts it into electric energy for sending wireless signals to the internal wireless module. Summary of hands-on debugging 1. The battery saving of linbellG4 self generated wireless doorbell not only saves the cost of the battery, but also brings many unexpected benefits, such as waterproof ability. Since there is no battery, no matter how much water enters, the internal circuit will not be damaged. No longer need to worry about the leakage and corrosion of batteries caused by wet weather; 2. Officially, it is easy to press repeatedly for 200000 times, and it can be easily used for 20 to 30 years without pressure; 3. The unique one button mute is more considerate. The volume button can be installed for 3s to keep one button mute. 4. The host has ultra-low standby power, which is safer and more environmentally friendly; 5. 25 kinds of polyphonic ringing tones, with unique sound and light coordination, suitable for all kinds of people; 6. The ring is flashing, so that you will not miss the guests' visit. The receiver button and the luminous body are integrated, and the sense of technology is full; 7. The signal penetration is strong, and it can easily penetrate several walls at a long distance, which is no less than those ordinary doorbells on the market called ultra long distance; 8. Later, I have to mention the battery. The ultra small energy collection module perfectly replaces the battery, which is environmentally friendly and pollution-free. If you are in the process of decoration, you can consider the self generating wireless doorbell of LinkedIn Technology. Although the price is higher than other doorbells on the market, you don't need to worry about removing and replacing the battery in the middle of the process. Of course, if your home is relatively large, you don't need to buy multiple doorbells. The receiver has the relay and forwarding function. You only need to buy a transmitter to expand the wireless signal and extend the transmission distance through the relay function. You no longer need to worry about the embarrassment of not hearing the doorbell in the bedroom.

The doorbell is a product that we often use in our daily life, which brings us a lot of convenience in our home life. Most doorbell products on the market are integrated in the anti-theft door, so there is no need to buy and install them separately. However, the doorbell on the anti-theft door is of average quality. It is inconvenient to replace the battery, and the sound is low. It has basically become a decoration. In order to solve one of the embarrassments, today's small editor brings us a self generating wireless doorbell product - LinkedIn LinbellG4 self generating wireless doorbell. First of all, thanks to the trial opportunity of LinkedIn LinbellG4 wireless doorbell provided by Yizhi Mushroom trial platform. In terms of packaging, LinkedIn LinbellG4 self generating wireless doorbell is packaged in kraft paper, with product name LOGO and appearance sketch printed on the front of the package, and relevant functional features and product parameter information printed on the back of the package. After removing the drawer type waist seal, you can see the inner packing box. After opening it, you can see that the transmitter and receiver of LinkedIn LinbellG4 self generating wireless doorbell are inserted inside, effectively avoiding damage during transportation. LinkedIn LinbellG4 self generating wireless doorbell package contains transmitter, receiver, instructions, two expansion screws and a piece of 3M double-sided adhesive tape. The placement of accessories brings a lot of convenience to the installation, which is comprehensive. LinkedIn LinbellG4 self generating wireless doorbell transmitter and receiver adopt white shell, which is small and beautiful. The external dimension of the transmitter is 83mm * 46mm * 20mm. The top of the front is printed with the product appearance logo, and the lower pressing position has a round highlight concave point, which is very simple. It can be seen from the side that the transmitter is very thin, and the pressing cover has a certain slope, which is well integrated with the base. The transmitter adopts the self generating mode, which eliminates the tedious battery replacement. It can cover a large area of 80 meters outdoors and 30 meters indoors, and has a good wall penetration ability, which is practical and convenient. There is a removable cover plate on the back of the transmitter for fixing when installing with screws. Due to the signal strength, it is not recommended to stick the transmitter directly to the metal surface. In daily life, our doorbell is not firmly installed on the wall by direct sticking, so it is better to use screws to fix it on the gray wall. When used on the ceramic tile wall or glass, the transmitter is very convenient to install, and can be directly pasted on the surface, which is convenient and firm. The receiver adopts two plug DC power supply mode, with standby power of 0.25W and flexible placement. However, it needs to occupy a socket, which is not convenient in actual use. There is a horn below the plug, and the sound of the horn is very clear. The volume of LinkedIn LinbellG4 self generating wireless doorbell is adjustable in 5 levels, and can be muted to avoid disturbance. In terms of music, LinkedIn LinbellG4 self generating wireless doorbell provides 16 kinds of music, which makes up for the shortage of traditional doorbell, which is more personalized. The more important thing is that it can realize the setting of "one for two". It is very ingenious to distinguish visitors at different doors through different ringing tones. To sum up, as a small product, LinkedIn pays great attention to the pain points of traditional doorbells, and has made great improvements in product appearance design and functions, making a small product more distinctive. A small change brings infinite creativity to life, makes life full of more fun, and expects LinkedIn to have more improvements. Netizen comments
