Electricity is an indispensable energy source. Without electricity, we will lose the vitality around us, and the earth will become a "black ocean." Today, IoT products are becoming more and more popular in our lives, and batteries are especially important, and a battery-free IoT sensor technology is revolutionary. At the Intelligent Lighting Sub-forum in the afternoon of the 3rd IoT Conference, e-fans invited Su Zijie, the marketing director of Einson, to give a live speech. He will tell us how the Principal does not need a battery on the IoT sensor.
Su Nengjie Marketing Director Su Zijie
Su said that in the past, the traditional sensor could not be separated from the battery. If a sensor is equipped with a battery and replaced over time, the consumption should not be underestimated. So in the future, energy harvesting applications on sensors are another trend in IoT. Now many manufacturers are pursuing low power consumption, trying to extend the life of the battery, but Ionsen is thinking about how to get rid of the battery.
According to General Manager Su, Powereng uses a unique energy harvesting method to convert other energy into electrical energy for use by sensors to get rid of the battery and achieve energy conservation and environmental protection.
So what energy harvesting methods can I replace the battery? Su is listed in three to four categories: the first is mechanical energy, which is the energy produced by the object in motion; the second is light energy, which is accurately indoor energy, mainly used on sensors, such as light perception, Passive infrared detection; the third is temperature difference energy, mainly used for heating in the north, the temperature difference will generate electricity, and it is frequently used on water vapor thermometers. General Su said proudly: "These technologies have been commercialized."
Someone asked, where is the core technology of the energy harvesting? Su said that "most people look at RF, hardware specifications, and consumption during transmission and reception. But the protocol itself is especially important. Hardware is a carrier, but software is the core, just like classical Chinese. The role of a small number of words. This is the importance of the agreement, but also the core of the power acquisition technology."
From the perspective of the agreement, the protocol of the device is very standardized from the physical layer to the application layer. Although the flexibility is not high, from another perspective, the network protocols of the various networks in the market cannot be interconnected. However, Isonsen realized this problem long ago, and now, users all over the world can use the Emerson products to achieve interoperability.
Speed ​​comparison of the power acquisition technology compared to other mainstream protocols
In Europe, the company's brand is familiar with the manufacturers of lighting control and building. Compared with the ZigBee protocol, the product usage rate of the company is higher, and it is more suitable for buildings with light control. Now, if you want to apply for energy-saving certification for commercial buildings in Europe, using Eonson products is one of the only standards that can get extra points in wireless protocols.
Mr. Su believes that in these buildings, the wireless way is still very difficult to replace the cable. Nowadays, most of the 20-story buildings still use wired combined lines. Therefore, the concept of the company is to use the cable in the main line and use it in the area management. wireless. Because it will be more stable.
For the control of intelligent lighting, Su always understands: Today, most smart lighting products usually need to open the phone first, then find the APP, and then control the lighting. But this is unreasonable in many application scenarios, it is very cumbersome, not everyone can be willing to accept APP control, so physical buttons are still necessary now, excellent intelligent lighting experience should be able to provide users with the convenience of work and life. And comfort, and Power can do just that.
Today, the company's products have been successfully used in more than 500,000 buildings. 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 by the world. Yi Nengsen always strives to make changes and make innovations to help people create safer, more energy-efficient and beautiful living environments and conditions.
