Definitely a useful application. I once built a system to monitor multiple walk-in freezers that would phone and email staff when the temperatures started to exceed limits. It saves a large expense every time it flags a door that is ajar.

Good idea.

One thing I have noticed about restaurants is that there are many times with a few seconds saved can be a big help.

Mark,

Sounds like a great project and a great starting point. I have friends who have considered very similar systems to deal with the temperature monitoring requirement. It seems to be a 'real life' problem in need of a real solution.

Good luck,

Gene

Interesting project!

Have you considered using a Type K thermocouple with a MAX31856 ADC? It'd be interesting to see how it compares to the DS18B20 sensors.

As [mention:8fb233e8974445138ef0af2b63b49f94:e9ed411860ed4f2ba0265705b8793d05] suggested, a door sensor seems to be a nice feature to have: if the door is left ajar, you'll have something to warn you before the temperatures start dropping and overload the compressor.

If you combine it with the NFC reader, you'll also know which employee left it open; though at this point the project will turn into a access- logging system.

It is a great solution to what has already been an issue.

The automation may still require checking to meet the state regulations, BUT you could add a button that the staff need to press after observing the temperatures.

This is then timestamped and sent (as well as logged) for proof of the check process happening.

Personally I'd be adding the door alarm warning, just to reduce the power bill if it does stick or get left open.

If someone wanted to expand on the button, you could use NFC reader and issue each staff member with their own tag to do the checking.... [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-8407086f-d312-478f-a952-62a7332c59f9/contentimage_5F00_930.png:16:16]

Hi Mark,

This sounds like a useful project. One of my friends installs similar commercial solutions as part of his business. Also congrats on being a sponsored project, its awesome to see another Aussie in the mix [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-8407086f-d312-478f-a952-62a7332c59f9/contentimage_5F00_1.png:16:16]
