The Internet of Things has attracted a lot of influences due to its huge market size, but the focus of many manufacturers is different. It is predicted that in 2020, the United States will become the largest single country market for smart homes, with a market size of 21 billion US dollars; the market size of Western Europe will reach nearly 10 billion US dollars. Next, Xiaobian took stock of the top ten smart home products for everyone. For the current smart home market, many industry insiders say that smart lighting will be the best entry. When it comes to smart bulbs, many people may think of the Philips Hub right away. Just connect Wi-Fi with the matching mobile app and make simple settings. You can control the Hue bulb installed in your home and change the color according to your mood. Last August, Philips introduced a new smart light bulb that does not require a Hub Control Center. The product consists of Hue Wireless Dimming bulbs and remote controls for $40 (about 255 RMB). This new product has a brightness of 800 lumens under 2700K soft lighting and a service life of approximately 25,000 hours. Although the Hue Wireless Dimming bulb can't adjust the color of the light, the brightness of the light can be adjusted by the remote control, which is convenient for home users. Its maximum remote control distance is 30 meters, which can meet the requirements of ordinary household users. It can control up to 10 Hue white light bulbs, and it can also be connected to multiple remote controllers by one light bulb. Compared with other bulbs, this Philips bulb can be turned on to achieve maximum brightness, while traditional energy-saving lamps need to be turned on for a while. The remote control is powered by a CR2450 battery, and Philips can at least 50,000 clicks. Let Nest be mentioned frequently because Google announced in January 2014 that it would acquire the entire assets of smart home company Nest Labs for $3.2 billion in cash. This incident is also considered to be a smart home boom, but it turns out that smart home is still a long way from us, but Nest has received much attention since it was acquired by Google. Nest released the third generation Nest thermostat in 2015. The new Nest thermostat features a new design with a larger screen and a slimmer body with several new features. Like the first-generation Nest thermostats released in 2011, the new products still rely on built-in sensors to determine the user's position, and then use intelligent algorithms to create a customized, automatically adjusted temperature control solution that cools the room temperature. Thermal control. Of course, the user can also use the Nest app to manually control the temperature in any place with Wi-Fi or network connection. However, these once revolutionary features seem to be nothing new today, and brands such as Ecobee and Honeywell have introduced similar devices to compete with Nest in the smart home market. Fortunately, the third-generation Nest thermostat was completely redesigned, and a far-field sensor was added to activate the screen at a certain distance to view the current time and temperature. The price of this product is 249 US dollars (about 1588 yuan), the same as the previous listing. With the release of the new product, the price of the second-generation Nest thermostat is now reduced to 199 US dollars (about 1270 yuan). On November 6, 2014, Amazon launched the smart speaker Echo, which installed the audio control assistant service Alexa. For the newly launched products, Amazon has not actively promoted the publicity, so that people remain excited and expect. Compared with the launch of the Fire phone that year, Amazon has a lot of low-key, it just said that Echo will be launched and will sell, but at the beginning only the invited Prime members can purchase. Soon, Echo won praise for himself. It has been found that the cylindrical Echo is really a new consumer electronics device. The concept of the product excites the user, and then the new experience that Amazon brings to the user also satisfies the user. The Amazon Echo can be used as a smart home control and a portable speaker that is 10 inches high and has a cylindrical design that can be placed anywhere in the home, including the kitchen. Echo supports Wi-Fi connectivity and can play music from online streaming services like SpoTIfy as a Bluetooth speaker. In addition, Echo can provide a variety of information and reminders, and rely on voice commands to activate. Because Echo uses echo beams and noise reduction technology, you can receive voice commands even when you are in another room or playing music. At this time, it was Alexa's turn to play. Alexa is a personal virtual assistant pre-installed in Amazon Echo that can receive and respond to voice commands. Alexa can be viewed as an Amazon version of the Siri voice assistant. When using Echo, just say "Alexa" and you can start asking questions, including news, creating task reminders, setting alarm time or playing music. At the same time, Alexa can interact with a variety of smart home devices to control the thermostat or mediate the lights, which looks cool. Alexa can handle any grammar, so users don't have to use a too blunt tone, which Alexa can recognize. For an efficient firing process, raw materials need to be optimally prepared.
