Let’s create a temperature and humidity monitoring and logging system with Arduino Nano ESP32 that can be consulted via the web.

The system allows us to acquire temperature and humidity, store them in a database, and consult them in real time from the web with a responsive interface.

It is possible to see the data in real time or consult the history directly on the video graph. It is possible to set a temperature alarm threshold, which if reached or exceeded sends an email. We can also export the data in Excel format.

The project is completely free, editable and does not use Arduino Cloud.
