All the codings of the individual sensors is compiled in one program where the program enables data transmission to the cloud server. The WiFi Id and password is set up in the coding (on the highlighted part in the picture below) to successfully connect to the WiFi connection.

Each of the sensors used is designed with its specific variable in the coding to be called out to display the data on the dashboard by accessing the specific IP address. The data won't be display properly or it will display nothing at all if wrong variables is set on the node-red.
