Notification when data arrives in Firebase

Question

I want to know how to send a notification to a user when new data arrives in Firebase. Since I am running an IoT project, so the sensors will send a text file to the Firebase repository. Upon receipt of the file, Firebase will send a notification to the user. How can I do it?

You can create firebase cloud functions that run when data changes in the firebase database to send firebase cloud messages.

Here is a complete example that shows how to use cloud functions to process database events in real time.
