Raspberry RPI3 - monitor temperatura

Sorry I thought I was in an Italian thread If someone manages to translate with google, otherwise I will soon translate Thankyou Roby

I have some notes (in English!) here:

if they help at all.

Have a look at:

Thanks for the answer I'm trying to accomplish the temperature monitoring with two DS18B20 probes The probes work well and I can see the temperature with cat / sys / bus / w1 / devices / 28-123456ffffff / w1_slave

I have been following this project (in English):

OK, Roby, sorry I couldn't help further.

I have used rrdtools to graph the temperature exterior and interrior. Andre

I based my temperature logging and graphing on this:-

I've got mine set up to log my 4 Raspberry Pi's internal temperatures on one graph, and another has the 4 sensors from my Oregon Scientific Bluetooth weather station, augmented with another two temperature and humidity sensors on the Raspberry Pi's. Instructions on that are here:-

A third graph logs a T/H sensor and 5x DS18B20 probes every minute (the others are every 15 minutes) which is useful for things such as balancing the radiators or getting the correct temperatures in the fridges and freezer.

Very interesting.... thanks. I read carefully this project. I have installed MySQL with sudo apt-get install mysql-mysql php5-mysql-client server MySQL and sqlite3 are two different things ? I guess so ...

Definitely. On a RPi and for simple applications, I think you'd be much better off using lighttpd + sqlite instead of apache + mysql. Sqlite is not a separate database, it's just a library that provides a SQL way of storing/retrieving data. It's built into PHP, no need for extra servers or installs. (Sqlite3 actually, previous versions no longer supported in php5+.)

However, there are many more examples of mysql interaction, and sqlite requires working with classes in PHP which may not be up your alley. See

Very much so, MySQL is a traditional style SQL server with a variety of backends (some really rather good) for table storage while sqlite3 is a library that implements a SQL interface good for simple applications with minimal concurrency.

sqlite3 can easily be used from python. I'm using uwsgi to allow nginx to run python scripts in cgi-bin.

Right, can be used in lots of languages. I meant: *if* you're using PHP then, etc.
