I have a shell script that monitors hardware stuff - it needs to run

In the end  setting a passwordless sudo for the www-data user for that script only, worked and was the first method to do so, so I stopped there.

Things are going to be a bit more complicated if you're in chroot.
A small C utility that wraps exec and provides suid should be ok.
 

I have done that in the past.

Another way is to call the script form cron and place the output
in some location where apache can get it.
 

I want very fast up to date response when I am on the web site and dont care when I am not, so that inclines towards a real time script.
