In this lab work, students are also required to implement a CoAP server-client and establish a connection among several components. The project is designed to:

(1) get the dummy sensor data (e.g., temperature and humidity),

(2) send the collected data to a time-series database,

(3) store the dummy data into the time-series database, and

(4) display them in a graph.

The entire project is split into four separate microservices:

• CoAP client -- is a CoAP client-side microservice that will be used to collect the dummy sensor data (temperature & humidity) and send them to the server.

• CoAP server -- is a CoAP server-side microservice that will be used to acquire the dummy data from the client and send it to the database to store those.

• influxdb -- is a time-series database and will be used to store the dummy data for future reference / use.

• grafana -- is a graph microservice and will be used to show the dummy data in a graph format.
