Storing sensor data in DB

I have a solar monitor device that emits 10 parameters per minute, in Json format. What is the right way to store the data in DB:

• shall all minute entry be a separate document,
• or to keep all data from one device in one document,
• or to have multiple time-limited (daily, monthly) documents for one device?
• shall have separate collection for each device?
  What is a reasonable number of collections and documents to deal with?

Single vs multiple documents per data point is up to you depending on how you'll be using the data.

I typically create a collection per data type and void having multiple collections with the same schema

A collection should be able to handle billions of documents. Under the hood, a collection is a mariadb table so refer to the limitations there: https://stackoverflow.com/questions/56474252/max-number-of-records-can-mariadb-support
