Ten years ago or even five years ago, it was just a concept to do Nest smart home. Because sensors, processors, and storage are expensive, the cost is too high; there is no high-speed wireless network support, no concept of cloud computing, users do not have smart phones, and there is no mobile Internet.
Google's sky-high acquisition of Nest attracts attention, which also allows the industry to see the energy that smart homes are booming.
Smart home is not a new topic, why has it been hot again recently?
Smart homes and the Internet of Things have emerged to meet people's daily needs.
Whether it can become popular depends on the actual effect. In other words, whether the smart home provides a better experience than ordinary non-smart ones, and the increase in cost is within the acceptable range. Whether the Internet of Things has brought tangible efficiency improvements to the industry, the benefits are higher than the costs paid.
Smart homes and the Internet of Things have recently become popular because of recent technological advances, which has further reduced the cost of hardware and software and hardware of the smart homes and the Internet of Things, resulting in increased revenue, high cost performance and practicality, and initial market competitiveness.
Take the simplest face recognition access control as an example. Face recognition access control system, as early as 2004, there were intelligent home products displayed, but the price of the 1.3-megapixel camera was dozens of dollars at the time, and the recognition effect was also very poor. It was necessary for someone to post the face and recognize a few feature points. can. At that time, the embedded processor recognized by the user was tens of dollars or even hundreds of dollars, and the recognition speed was very slow, and the recognition rate was also problematic.
At that time, the intelligent access control had poor recognition effect, the price was extremely high, and there was a display but no market.
In 2014, the 8-megapixel back-illuminated camera cost only ten dollars, and there is no problem in accurately recognizing a human face from a meter. After 10 years of progress, the performance of the processor has increased by several tens of times, and the price is only a few dollars.
In 2014, the intelligent access control system has high recognition speed, high accuracy and low price, so it has practicality and competitiveness.
Similarly, the core of the Internet of Things is the GPS positioning chip and the networking chip. A few years ago, both the price and the power consumption were problems, but now it is not the problem.
Therefore, the smart home and the Internet of Things are not reheating, but the demand has always existed. Recently, because the technology has reached the threshold of practicality, the smart home and the Internet of Things are changing from concept to reality. Acquired the pioneer company Nest.
Nest's flagship product is a thermostat, which is characterized by a large number of sensors that monitor the temperature, humidity, light in the room, and the environmental changes around the thermostat, determine whether someone is moving in the room, and decide whether to turn on the temperature adjustment device.
It records user settings, daily work habits and temperature preferences, uses an algorithm to generate setting schemes, and also supports remote remote control via network.
Nest's monitoring functions come from temperature sensors, humidity sensors, light sensors ... These things have existed for a long time, but the cost has been reduced. The large-scale popularity is the development of smart phones in recent years. The sensors are implemented as smart phones integrated into the sleeve. In the past, high-power temperature sensors cost US $ 2, but now the power consumption is only US $ 1 for one-hundredth temperature sensor. Previously, single-axis acceleration sensors cost $ 5, but now three-axis acceleration sensors cost only $ 1.
Nest's processing and storage of collected information (judging whether there are people by light sensor, storing user's usage data, and using algorithm analysis) requires a microprocessor and memory. If complex algorithms are involved, they will be uploaded to the server for calculation and then returned.
Nest's local information storage and processing uses ARM A8 processor, 512M memory and 2G flash memory. High-performance, low-power, low-cost microprocessors and memories are also the result of the rapid progress of embedded processors in recent years. A low-frequency ARM 9 processor with 10 times weaker computing power was expensive. Uploading server computing returns has involved popular cloud computing applications in recent years, similar to Apple's Siri.
Nest's support for remote control has benefited from the development of mobile communications and smart phones in recent years. Mobile communication provides 3G and 4G high-speed low-latency wireless networks, and smart phones provide terminal devices that can be controlled.
Ten years ago or even five years ago, it was just a concept to do Nest smart home. Because sensors, processors, and storage are expensive, the cost is too high; without high-speed wireless network support, without the concept of cloud computing, complex computing cannot be handled; users do not have smartphones, no mobile Internet, and remote control cannot be achieved.
Now that technological progress has reached the threshold of practicality, Nest's smart thermostat provides a better experience, and the cost is within the acceptable range. The market is welcome and represents the future trend. Google is also willing to buy.
