How to read a temperature probe, save the value to a MySQL database and then show the value on a webpage or just show the value with no database.
See this link for how to setup a DS18B20+ thermal probe with a Raspberry Pi, these instructions are the best that i have come across for this and will cover the bullet points below :
- Enabling the 1 wire features in the Raspbian OS
- Physically connecting the probe via a resistor to the RPi
- Instructions on how to read the probe and a script example
Once you have followed the above steps you should have a working temperature probe, that’s great.. but what can you do with it now!?
