Raspberry Pi Thermal Probe

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!?

For the piTank/piGrow projects,  I started off by just using the script provide in the instructions above, modifying it slightly and using that to display the temperature value on the piTank web-page. Using some JavaScript you can make the box’s refresh every x seconds, running the probe read script and showing a new value without the need for a page reload.  I call this a ‘live’ reading.

Configure Client Network Time (NTP)

Information directly copied from : –

for quic ref…

 Windows 7

Windows 7 systems benefit from using the full set of NTP servers, but cannot be configured to obtain NTP server information from DHCP. Because the control panel does not allow setting multiple servers, settings on these systems must be verified and changed from a command prompt. Systems which are members of the SCS domain will receive NTP configuration via domain group policy and should not be reconfigured.

Li-ion battery overcharge

So one day I left a Voyo A1 mini tablet charging for a little too long, I thought, oh well – I will replace the battery at a later time and just leave it in a box for now.

Leaving an over charged Li-ion battery in a box for 7 months isn’t the best things to do ….


Sorting some things out some time later I found the unit and wondered why the box wouldn’t shut completely, a peak in side and I see the below! luckily the box wasn’t kept next to a heat source as i guess things could of been worse.
