Do you know what the most popular IOT sensor is

Do you know what the IOT sensor is close to life

sensor is a kind of physical device or biological organ, which can detect and collect information about the surrounding environment and transmit the detected information to other devices or organs. These sensor devices can be the net profits attributable to the parent company of 75.1230 million yuan, 78.6602 million yuan and 56.4331 million yuan respectively. Electrical, mechanical, magnetic, electromechanical, electromagnetic, optical or chemical sensors are placed near the place of use or network, and there are various sizes according to different applications. They can be separate components or integrated into other products, such as installing in the engine, intelligent temperature controller Smart watch, smart; The data collected by the sensor is sent back to the central network for storage and processing

nowadays, only IOT sensors have entered our lives. However, if you want to install them, you need to consider the following matters:

what application is it? Depending on the purpose, the sensor can be installed in a limited space (such as room, building) or at a far distance (such as in the construction site of restoring cell elasticity). The specific purpose determines what type of sensor to use, what data to collect, how to send data, and the location of the sensor

what data need to be collected? For key tasks or time sensitive data, sensitive location data or the collection of some geospatial related data, precision data requires higher precision sensors. Combined with specific applications, determine which secondary data sensors need to collect in addition to the main data, and clarify the accuracy of the collected data

how often is data collected? It can be collected continuously at preset intervals, or trigger events to start data collection, or basically collect plastic line data as needed. In continuous manufacturing applications, such as chemical processes, sensors need to continuously record data, but not all applications need to collect data so frequently

under what environment does the sensor operate? When the sensor works in harsh environment (pressure, temperature, vibration, radiation, etc.), it needs to be protected to ensure its stability and sustainability

how much data should be collected? Some sensors collect only a few bytes of data, while others (such as cameras) collect megabytes of data. The more data collected, the larger the storage capacity, and the higher the requirements for the data transmission process

frequency of data transmission back to the central network? Applications with mission critical or time sensitive data need to send data and process it immediately after data collection. Other applications, such as autonomous vehicles, need to transmit sensor data to the local computer center for processing, rather than to the central network. From the perspective of energy, the higher the frequency of data transmission, the greater the power it consumes

How can data be sent back to the network center? The data collected by the sensor can be transmitted by cable or sent wirelessly. The specific application will determine the transmission mode

how to power the sensor? IOT sensors can be powered by batteries, solar energy or cables. The sensors installed in remote areas or difficult to reach locations can be used to complete different experiments, such as battery power supply or solar power supply. However, it is also an arduous and unrealistic project to replace the batteries of thousands of sensors in remote areas. In these applications, sensors should be low-energy and efficient, so as to make the battery life longer. The higher the data transmission frequency is, the greater the data transmission volume is, and the more power is consumed. In this case, the power technology and energy supply mode of the sensor need to be considered

what are the safety requirements? Sensitive or confidential data needs to be encrypted before transmission, and the sensor needs to be authenticated before data processing in the central network

data format requirements? Different applications have different data formats. When data is sent back to the central network, the platform must be able to integrate all data in different formats

what is the total cost? The total cost includes the cost of purchasing the sensor and all costs incurred in the whole process of installation, integration, operation, maintenance, replacement and final disassembly. Compared with the sensor network made of a large number of cheap sensors, the cost of a small sensor network composed of a small number of expensive sensors is lower

what specific technology is required for the installation of IOT sensors? Some sensors are part of the IOT ecosystem and are easy to configure. They can be deployed with limited programming, while others may require special programming and integration
