5           communicating protocol

5.1     Protocol parsing instructions

For TCP / MQTT and other push methods, users should provide the public network IP (or domain name) address and port number of the cloud server to receive the data.

Example of JSON format:

{"flag0.3":51707.00,"flag0.5":9214.00,"flag1":622.00,"flag2.5":56.00,"flag5":16.00,"flag10":0,"tmp":16.75,"humi":26.28,"dp":-2.78,"diff":-0.01,"ID": " 30204BR221TODE88 "}

Message analysis:

{

       

"Number of flag0.5":9214.00,//0.5um particles

"Flag 1": 622.00, / / 1um number of particles

"Flag 2.5": the number of 56.00,//2.5um particles

"Flag 5": 16.00, / / 5 number of um particles

"flag10": 0, / / 10um particles

"Tmp": 16.75, / / temperature value

"Humi": 26.28, / / humidity value

"dp": -2.78, / / dew point value

"Diff": -0.01, / / pressure difference value

       

}

 

5.2     Agreement customization

If you need to customize other communication protocols, you can contact the business personnel to communicate.

6           Platform docking

6.1     Default platform

The product is connected to our designated open industrial Internet of Things platform by default, and the platform interface is as follows:

 

Computer-side browser interface

 

Mobile terminal access interface

 

6.2     The user specifies the platform

Take the connection of Ali Cloud platform as an example. After users create products and add devices on the Ali Cloud Internet of Things platform, users need to provide a triad: {ProductKey, DeviceName, DeviceSecret} and MQTT theme to be released.

For example, the value of triples are:

ProductKey = b0FMK1Ga5cp

DeviceName = **************1

DeviceSecret = y7MTCG6Gk33Ux26bbWSpANl4OaI0bg5Q

 

7           matters need attention

This product is the default built-in Internet of Things SIM card, the traffic fee is about 20 yuan per year, including free technical support fees and lifetime maintenance costs. If you need to use the user's own SIM card, please inform you in advance.
