IoT Service Oriented Based On Raspy- Huawei Cloud

IoT Service Oriented Based On Raspy- Huawei Cloud Is an IoT design based on service oriented for each device/node of an embedded system

The system generally consists of 3 major parts:

1.  Frontend
2.  Backend
3.  Microservice

Frontend is the system that will consume the API provided by the Backend Gateway. The frontend can be a website or mobile phone.

Backend is a system that provides services or endpoints that will later be used or accessed by the Frontend. The backend receives sensor data from each node or device. Delivery data from each node will be stored in the Gateway database. all data that has been collected in the MySql database will be created as an endpoint for consumption by the Frontend. The backend system was built using the Python language using the FLASK framework. The following is an example of an endpoint for posting sensor data to a server which will later be used by the Node/Device as a data delivery medium. The backend uses Ubuntu OS and uses Cloud services from Huawei. for the endpoint it is set on port 5021

Microservices in IoT are usually known as nodes or devices. The node will send data in real time every 1 minute which is arranged using the croneJob Scheduler on deviceIoT. deviceIoT uses a Raspberry Pi Microprocessor and 3 sensors connected directly to the GPIO. each sensor output will be sent using the http protocol with a RESTFull API-based API architecture
 

The data frequency will be sent using the CronJob Schedule on the Rasberry Pi. In this case, it is set to send data once every minute to the server. the following configuration:
 

The following are the results of sending sensor data to the MySQL database on the Gateway
