With the development of society, the measurement and control of temperature becomes more and more important. Temperature is a common and important physical parameter in the production process and scientific experiments. In the industrial production process in order to efficiently carry out production, the main parameters of the production process, such as temperature, pressure, flow, speed, etc. must be effectively controlled. Among them, the control of temperature occupies a considerable proportion in the production process. Accurate measurement and effective control of temperature is an important condition for high quality, high yield, low consumption and safe production. In industrial development and production, in order to ensure the stable operation of the production process and improve the control accuracy, the use of microelectronics technology is an important way. Its role is mainly to improve labor conditions, energy saving, prevent production and equipment accidents, in order to obtain good technical indicators and economic benefits.

Third, the experimental steps
1, register new users on the OneNET platform
2, add products
3, add equipment
4, temperature and humidity monitoring terminal device access
Write the terminal software to collect data, burned into the development board, through the NB-LOT network access to the OneNET platform. And upload data to OneNET
5, master the temperature and humidity detection system device access logic diagram
6, NB-LOT device access OneNET flow chart
Create products, create devices, B-LOT device connection, device subscription, device information view, data reporting, resource list view, object instance operation
7. M5310 device-side access
Device deactivation, resource configuration, network configuration
8. Access to NB-LOT network
The NB-LOT network access process is a necessary step before the module can carry out normal data communication services. In the initialization, the module is about to complete the process of network searching, residing in the network, attaching, etc.
9. AT Command
Setting Command AT+<cmd>=p1[,p2][,p3[....]]]]
The test command AT+<cmd>=?
Execute command AT+<cmd>
Read command AT+<cmd>?
10. ACCESS ONENET
1) Set the device registration code in the module
AT+MIPLCONF=<size>,<config>,<index>,<flag>
2) Add to the module the Object resource
AT+MIPLADDOBJ=<ref>,<objectid>,<instancecount>
3) Subscribing to Resource resource to the module
AT+MIPLNOTIFY=<. ref>,<objectid>,<resourcied>,<valuetype>,<value>,<flag>[,<ackid>]
4) Initiating a registration request to OneNET
AT+MIPLOPEN=<ref>,<lifetime>[,timeout>]
After the server receives the login request data, it will return the result of this login according to the content of the data
