IDC predicts that worldwide Internet of Things (IoT) spending will reach $805.7 billion in 2023, an increase of 10.6% over 2022. Investments in the IoT ecosystem are expected to exceed USD 1 trillion by 2026, at a compound annual growth rate (CAGR) of 10.4% during the forecast period 2023-2027.
IoT services will be the largest spending area by 2023 and account for nearly 40% of global IoT spending by the end of the forecast. Hardware spending was the second largest technology category, dominated by module/sensor purchases. Software will be the fastest-growing technology category with a five-year CAGR of 11.0%, with a focus on application and analytics software purchases.
Western Europe, the US, and China will account for more than half of all IoT spending throughout the forecast period. Despite the similar current spending levels in Western Europe and the U.S., Western Europe will extend its lead at a CAGR of 11.0% during the forecast period 2023-2027, compared with 8.0% in the U.S. China is projected to overtake the US in IoT spending by the end of the forecast, with a CAGR of 13.2%.
With the widespread adoption of IoT devices in consumer electronics, standardization and interoperability through IoT communication protocols is critical. These improve user experience and enable smooth data sharing and communication between devices. The use of IoT has recently increased significantly across the world. There are approximately 8.6 billion IoT devices in the world in 2019. With the accelerated adoption of IoT devices worldwide, the total number of IoT devices is expected to reach 12.14 billion by 2022. By 2030, it is expected that there will be approximately 23.14 billion IoT devices on the planet. Furthermore, as more and more IoT devices are used across the globe, the demand for IoT communication protocols is expected to increase throughout the assessment period.
Bluetooth low energy plays an important role in the smart home to reduce wiring. Moreover, Bluetooth Low Energy can collect data in the room and monitor the function in real time to realize the connection of wireless smart home, security and other Internet of Things applications.
Bluetooth low power consumption is very common in our daily life, and has a wide range of applications. Household items in people's lives, such as intelligent control lighting technology, this technology is not only the control of light switches in the traditional sense, but also with scientific With the development of technology, people's requirements for lighting control are not only on the switch, but also include the change control of lighting color and type. Such as the light show on the Beijing Olympic Games.
Therefore, in today's life, the application of low-power bluetooth smart lighting control technology meets people's needs to a large extent, and can also meet people's needs. Smart home technology has a wide range of applications in people's lives. The places are different, and the smart homes of related companies divide them into the following aspects.
1. The control application of the living room
The application in the living room is similar to the control in the bedroom. It can control the lighting scene and entertainment facilities in the room, such as the control of audio equipment through lighting. Realize the control of curtains, air conditioners and other equipment through music equipment. It is also possible to control the electrical appliances in the home through the use of communication equipment.
2. Application of corridor control
The smart home control system not only realizes the control of lights, but also realizes the switch adjustment of lights according to the brightness of natural light. Specifically, it can be highlighted that when the natural light is bright, the brightness of the lights in the corridor will be dimmed. When the natural light intensity is low or there is no natural light, the brightness of the lamp will be automatically adjusted. In addition, it can also help people to carry out regular reminders, so that the lights can be turned on and off at regular intervals.
3. Indoor applications
Specifically for the lighting control system in the room, it can realize the switching and control of different scenes; it can also intelligently control electrical equipment such as curtains and air conditioners. In addition, it is also possible to control the electrical appliances and lamps in the entire room through mobile devices. Smart home control system is widely used in people's life. It not only enhances the safety of people's life, but also provides convenience and speed of people's life, making people have a happy mood in the process of life, so it is widely favored by people.
ST17H66 Bluetooth BLE5.2 chip is the latest 16-pin Bluetooth BLE chip launched by Lenze Technology. It has 256KB Flash + (96KB ROM) + 64KB SRAM. The Bluetooth protocol stack is solidified and no longer occupies Flash space. 64KB of SRAM, used in partitions, can save more user data during standby, and can set a large-capacity buffer to support more complex functions. Ad hoc network applications that comply with SIG specifications. Including multi-node control, and simultaneous work of 2 masters and 4 slaves.
ST17H66 has 10 x GPIO, -103dBm @BLE 125Kbps. Single-ended antenna output, no matching circuit is possible. Support antenna matrix switching, support external LNA signal amplification.
The biggest advantage is reduced power consumption. The previous generation of products Bluetooth receiving peak current > 13mA; MCU power consumption 0.5mA/MHz; average current > 40uA in low power mode. The Bluetooth receiving peak current of the new product is 8.6mA, and the power consumption of the MCU is <90uA/MHz. The average current can be reduced to 20uA 30uA in low power consumption mode. The broadcast packet of BLE5 is more flexible and can contain up to 200Byte data, while BLE4 only has 32Byte. The transmission rate is faster, BLE5 can reach 20 30KB/s; BLE4 is generally 4 5KB/s.
Application scenario:
Applications that have strict requirements on power consumption control, such as high-end anti-lost devices, electronic tags, etc.
Customers who have certain requirements for data transmission, such as the transparent transmission module used for gimbal selfies, and customers who want more reliable Bluetooth OTA.
Convenient and flexible electronic label application. Such as commodity labeling, asset anti-theft, biological tracking.
