Smart lighting devices without batteries Is it the law of energy conservation

Electricity is an indispensable energy source. Without electricity, the "life" around us will be lost, and the earth will become a "black ocean". Nowadays, IoT products are becoming more and more popular in our lives, and batteries are becoming more and more important, and a battery-free IoT sensor technology is revolutionary.

In the past, traditional sensors cannot be separated from the battery. If a sensor is equipped with a battery and needs to be replaced over time, the consumption cannot be underestimated. So in the future, the application of energy harvesting to sensors is another trend of IoT. Now many manufacturers are pursuing low power consumption and trying to extend the life of the battery, but DFM is thinking about how to get rid of the shackles of the battery.

DFM adopts a unique energy collection method. Through collecting other energies, it converts them into electrical energy for use by sensors, thereby getting rid of batteries and achieving energy saving and environmental protection. So what energy harvesting methods does DFM have that can replace batteries? We have listed three to four types: the first is mechanical energy, which is the energy generated by objects in motion; the second is light energy, to be precise, indoor light energy, which is mainly used in sensors, such as light-sensing, passive Infrared detection; the third is temperature difference energy, which is mainly used for heating in the north, and the temperature difference will generate electricity, which is frequently used in water vapor heat meters.

Someone asked, where is the technical core of DFM energy harvesting? We know that "the first thing most people look at is radio frequency, hardware specifications, and consumption during transmission and reception. But the protocol itself is also very important. Hardware is a carrier, but software is the core, just like classical Chinese, which plays a role in reducing words." The role of multiple meanings. This is the importance of the protocol and the core of the DFM acquisition technology.” Compared with the ZigBee protocol, DFM products have a higher usage rate and are more suitable for buildings with light control. Especially now that commercial buildings in Europe need to apply for energy-saving certification, the use of DFM products is one of the only standards that can get extra points in the wireless protocol.

We think that in some buildings, it will take a long time for the wireless method to replace the cable. Nowadays, most buildings with more than 20 floors still use a combination of wired and wired lines. Therefore, the concept of DFM is to use wired for the main line. Managed to use wireless. Because it will be more stable.

As for the control method of smart lighting, we understand it as follows: most of the smart lighting products nowadays usually need to turn on the mobile phone first, then find the APP, and then control the lamps. But this is unreasonable and cumbersome in many application scenarios. Not everyone is willing to accept APP control, so physical buttons are still necessary nowadays. Excellent smart lighting experience should be able to provide convenience for users' work and life And comfort, and DFM can do just that.

Today, DFM products have been successfully used in many families. In the future, the application of wireless technology based on energy harvesting has unlimited potential, which is in line with the low-carbon concept advocated globally. DFM always strives to make changes and make innovations to help people create a safer, energy-saving and beautiful living environment and conditions.
