Problems solved by technology

Although, there are relevant laws and regulations or moral constraints, but the above risks always exist

(2) The system provides an open platform to access websites or applications, and because it stores a large amount of user information and information about the user's IoT system, it is easy to attract criminals to conduct various network security attacks on it

(3) Users want to expand the functions of the Internet of Things, and it is difficult to develop by themselves.

Among them, microelectrode temperature sensor temperature measurement and infrared radiation thermometer temperature measurement are mostly used as a means of measuring local temperature, and the spatial distribution information of temperature cannot be obtained.

Although the temperature measurement of temperature-sensitive fluorescent indicators, infrared radiation imaging temperature measurement, and thermochromic liquid crystal temperature measurement can obtain the spatial distribution information of temperature, these temperature measurement methods can only obtain the information of the plane temperature field, and if necessary, the measurement results Converted to electrical signals or digital signals, these temperature measurement methods tend to introduce more external interference and errors compared to the temperature measurement method of the microelectrode temperature sensor

Moreover, in most of the research and application in the fields of medicine, biology, chemistry, etc. that use temperature as an important parameter or variable, there are often characteristics such as long experimental periods and many experimental times.

At present, most of the methods are pre-set in the device, and remote parameter setting is not possible. After the setting is completed, it is necessary to wait for the device to run for a long time. During this process, the status of the chip cannot be monitored in real time or remotely. Real-time monitoring and alerting

In the whole process, due to the low degree of automation and intelligence, the efficiency of the whole system is not high, the waste of time and manpower is serious, and it is prone to misoperation, and the system cannot be alerted in time when the system fails.
