Introduction to iot sensors
Sensor is an important part of the sensing layer, one of the three major hierarchies of iot, and is the foundation and premise of iot implementation. With the construction of smart cities, the rapid development of big data, as well as the increasingly widespread application of the Internet of Things, sensors, the main source of data from the most front-end devices show a rapid development trend. Especially in these two years, the explosion of the much-anticipated artificial intelligence industry, with the continuous strengthening of the sensor industry support, the iot sensor industry has embarked on the fast track of development. In 2017, the global sensor scale of nearly 200 billion, according to the McKinsey report predicted that by 2025, the economic benefits of the Internet of Things will be between 2.7 trillion and 6.2 trillion dollars. Among them, the sensor as the entrance of data collection, the "heart" of the Internet of Things, will usher in a huge development space.
Sensor technology is one of the world's remarkable rapid development of high-tech, but also an important symbol of the development of contemporary science and technology, it and communications technology, computer technology constitutes one of the three pillars of the information industry. It is due to the universal attention and investment in the development of countries around the world, the sensor development is very rapid. At present, the world is engaged in the development and production of sensors has more than 6,500 units. The United States, Europe, Russia, each engaged in sensor research and manufacturers more than 1,000, Japan has more than 800. 2007, there are about 10 million sensors around the world to connect various types of human inventions to the Internet of Things. 2013, the data reached 3.5 billion, and by 2030 is expected to reach 100 trillion.
Industrial control, automotive electronics, and information and communication become the fastest growing typical application markets. In addition, innovative applications in medical, environmental monitoring, oil and gas pipelines, smart grid, and wearable devices will become new hots pots and are expected to create more market demand in the future.
Behind the smart wear is the sensor competition, compared to cell phones and PC, smart wear data acquisition and input is no longer through the keyboard, touch, mouse and other manual way, most of them are through the sensor and cell phone, get from the user's voice, action and various environmental factors. This can free the user's hands, so that they can more easily enjoy the services from the device.
