I’ve recently purchased a few cheap DHT22 temperature sensors from Amazon.
They work great and use Python to display the data from the sensors.
I found I required a way to log the data, so I though why not make this a project!?
I have created a simple Web Interface to view logged data: https://github.com/ryanfitton/rpi-temperature-monitor-logging-interface.
This project is built using PHP, Python3 and Bootstrap for nice admin styling.
The project's GitHub page gives much more information on how to get-up-and-running.
Here are a few images:
