Subject: Temp Measurement without PID
As a budget restrained do-it-myselfer, I want to watch the water
temperature in my Gaggia Espresso without resorting to PID. Is anyone
aware of a low cost (how about $20?) temperature sensor that I can
install to monitor the temperature rise in the boiler, which would
allow me to hit the brew button with some knowledge of water temp?

Thanks,

Matt

PS This group has been invaluable to me in my espresso journey. Thanks
for that too.

The one Craig mentioned is probably the best bet... depending on
exactly what you want to measure. if it is static temperature then it
will be fine. The problem with many of the economy digital temperature
meters is that their display update is done at long intervals. Check
before ordering if that matters.

Possibly this tucked into the insulation by the boiler?

If you need something with a fast response it's going to be quite a bit
over $20. On the downside if this doens't work you can always use
it with BBQ. :)

Had one of those for a while. Great value. Should work fine for
monitoring boiler temps.

Although the following data are based on only a single sample, you
might find it interesting:
