Nest Protect for Prusa I3 (Web enabled Smoke Detector)

Hello

After having seen here and there that there was a fire risk to let a printer work alone (which I do very often), I looked for a solution that could warn me even if I'm far from the laboratory.

It suffices that the process stops for an unknown reason and that the head continually heats the block of printed material, worse if because of a bug if the feeder continuously provides filament under the hot head.

Not to mention the possible remote hack Prusaprint print server, a malicious person can take remote control of your machine to achieve this. Always change the default password of your Prusaprint server with a strong password. I read that bots are constantly scanning the net to find these servers.

So I bought a well-connected and well-connected stormwater sensor, Nest Protect.

It was then necessary to make him a support to fix it in an efficient way to the frame of the printer.
Just above the power supply seemed a good place.

You need a Nest Protect 2 generation
