Sensor and sensor network market demand analysis

Introduction: With the rapid development of the Internet of Things, the market demand for sensors and sensor networks is increasing, and the market prospects are considerable. This article simply analyzes the current market demand for sensors and sensor networks. If you have any objections, welcome to discuss them.

Public needs and personal needs

From the perspective of the application requirements of the Internet of Things, the IoT sensor and sensor network are mainly applied in the three major areas of public management, industry, and personal (mass) market. Among them, urban emergency (accidental disasters, natural disasters), social security, resource and environment management, smart city management, intelligent transportation, and public health are the key market segments in the field of public management in the near term; industrial control, intelligent buildings, and modern precision facility agriculture. Smart logistics and food traceability applications, smart grids (power saving) are the key market segments for recent industry applications, and the recent major market segments for personal (mass) applications mainly include smart communities and home applications.

The city emergency warning IoT system is an information processing system that connects all emergency information collection points in the city (including security systems, traffic systems, weather systems, and public security systems), and forecasts warnings based on the expert knowledge base, real-time through the network. Inform the city's emergency department to unify the public security, armed police, transportation and hospital departments to coordinate their actions. The sensor is mainly used in this field: harmful gas detection, image and identification, weather monitoring, and hazard monitoring.

Technical development needs

Technology promotion and demand traction jointly determine the development trend of the future sensor technology, mainly including four aspects: First, the miniaturization, micro- and even nano-level micro-devices, while bringing about the reduction of power consumption; Second, the integration, namely The integrated manufacturing technology of sensors and ICs and the integrated manufacturing technology of multi-parameter sensors; the third is intelligence, that is, further development on the basis of integration, which makes signal detection have certain intelligence; Fourth, it is networked.

Sensor network is an autonomous information system composed of many intelligent sensor nodes distributed in space. The nodes in the network use cooperative sensing and processing to monitor physical or environmental conditions (such as temperature, humidity, light intensity, sound, vibration, pressure, and movement) in different locations. Currently, the vendors that promote the development of the sensor network industry can be divided into three camps: ZigBee, Z-Wave, and Insteon. The largest industry camp is ZigBeeAlliance. Its ZigBee technology is mainly based on the IEEE802.15.4 technical specification. It has developed open and comprehensive products for various protocols such as link layer, network layer and application layer.

Since ZigBee technology maintains open standards, individual vendors' products only need to comply with the Zigbee communication protocol standard defined by ZigBee Alliance, and can quickly complete interoperability testing, facilitating manufacturers to develop multi-purpose applications, meeting residential, office buildings, and regional environments. In the area of ​​automation, control, and monitoring functions, WSN industry vendors rely on ZigBee technology vendors. In the future, these three major wireless sensor technologies will remain the dominant standards for the sensor network industry for a period of time.

Sensor requirements in other areas

Social security: National large-scale events, events, etc. have special requirements for safety. Through the combination of RFID identification technology and Internet of Things technology, it provides security for the real-time control of the personnel's movements and activities.

Resource and Environment Management: Internationally developed countries have formulated corresponding environmental protection laws and regulations and strengthened control and monitoring of the environment. China is no exception. In the future, environmental protection sensors will focus on areas such as water quality monitoring, air pollution, and industrial emission monitoring.

Smart City Management: The application of sensors in this field is mainly through embedding in roads, bridges, railways, public facilities, and sensing, analysis and management of urban environments, facilities, utilities, urban services, citizens, and local industries. .

Intelligent Transportation: The main applications of sensors in intelligent transportation include urban traffic guidance, urban traffic information collection, intelligent monitoring and recording of highway vehicles (bayonet), automatic recording of red lights, fixed high-speed speed monitoring, and integrated control of traffic commands. Electronic charging, traffic safety and automatic driving, parking management, traffic information collection and processing systems are the main scenes of recent sensor technology applications.

Public Health: Sensors in the public health sector focus on biological and chemical sensors for diagnosis and treatment of various diseases, food fermentation and enzyme sensors.

In such a good market demand environment, all major related companies want to profit, it is imperative to increase the development of new products and ensure the quality of after-sales service.
