Node-RED with IoT sensor

General
1

I would like to ask about how can we use Node-RED with IoT sensors. Node-RED use as translator and how?

Your question is very open, so the answer is yes.

Did you search the forum ?
Did you look at the documentation ?
How did you find Node-RED ?
What are you looking for specifically ?

Who told you that? If you don't understand what they mean perhaps it's best if you ask them to explain.

Have you succeded in reading sensor data into Node-red? What sensors are you using?
Have you managed to store the data in your database? What database are you using?
What is your Node-red application going to do?

Node-RED allows I to build a User Interface with buttons to control outputs and charts to display sensor readings.

Node-RED receives the sensor readings and can display them on the user interface.

On the other side, Node-RED can publish data on a specific topic to control outputs when I use the buttons on the interface. The other boards are also subscribed to that topic and control the outputs accordingly.

Could you be help me rather than make a lot of questions!

You will find lots of example flows at https://flows.nodered.org/ and at https://discourse.nodered.org/c/share-your-projects/6

Sorry, this question makes no sense to me. Perhaps our native languages differ.

What exactly do you mean by IoT sensors? How to use node-red with sensors depends on what sort of sensors, so it is difficult to help unless we know what sorts of sensors you mean.
