We touch doorbell, switch, keyboard and other micro electric objects every day, most of which need to be connected to electricity or use batteries, especially the doorbell. The built-in button/No. 7 battery generates electricity, and the wireless signal is transmitted by pressing the doorbell button with fingers. Therefore, the linbell G4 self generating wireless doorbell does not need that trouble. It can generate electricity by pressing the doorbell button, Transmitting wireless signals, doorbell transmitters no longer need batteries.

There are more or less problems with doorbells in the current market:

1. The doorbell on the burglar proof door sounds so low that it can only ring at the door, needless to say;

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 linbell G4 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. What about this product? Let's have a look.

Unpacking

On the front of the box is the product logo of LinkedIn Technology and the machine trial sticker of our trial platform

The English name and product name of LinkedIn Technology are on the side of the packaging box, which specially indicates the product feature "no battery, worry free and environmental protection".

On the back of the box are some functional parameters of the product

Unpack and see the transmitting end and receiving end equipment and some parts.

Take out the receiver and see that there are two buttons on the front, which are volume and music switching

On the back is the receiver plug and audio

The transmitting end is very simple. Apart from the logo, there is a groove, which seems to tell everyone to press it

Don't think it must be very thick without batteries. In fact, the thickest 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 and seems to have little content

After disassembling, I saw a lot of snap points. I was afraid that they were too violent, so I didn't disassemble them further. I saw that other testers had disassembled many circuit boards and simple coils.

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.

The last, of course, is our group photo

Principle analysis

Since there is no battery, how can Linbell G4 self generating wireless doorbell generate electricity?

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.

Hands on debugging

summary

1. The battery saving of linbell G4 self generating wireless doorbell not only saves the cost of the battery, but also brings many unexpected benefits, such as excellent 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. Unique one button mute, more intimate, install the volume button 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. Ringing tone+flash let you never 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 that are called ultra long distance;

8. Finally, 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.
