Humidity & Temperature Monitoring Systems
August 11, 2015 6:36 AM Subscribe
I'm looking for a solution for humidity & temperature monitoring for ~20 rooms, and also for refrigerators & freezers. (Can be separate monitoring systems). Text & email alerts are needed when the rooms or equipment fall out of range. Also needed is the ability to pull historical reports for 30 day ranges. Any recommendations from the hive mind?
We haven't used them on the scale you're looking for, but Phidgets makes temperature and humidity sensors, and their interfaces are relatively easy to work with. If you're looking for a roll-yer-own sort of solution, they at least have the hardware side set.

Best answer: I've used IT watchdogs for years for computer server rooms. They have a good range of small boxes that you could use 1 per room or 2, or you could get one "big one" and try to connect up all the sensors to it. Depends on how much sensor wiring versus computer network wiring you'd prefer to deal with.

ThermoWorks focuses on the foodservice industry makes a line of logging devices for temperature, humidity, etc.
They have recording and storage addons for HACCP compliance among other things. Their software can be set up to do alerts.

Best answer: We've been using the Omega iTHX series for about a decade on a series of fridges and walk-ins in a lab setting. This is the humidity/temp version. They're reliable. We get calibrations checked annual by ThermoFisher and we've never seen significant drift on more than a dozen units.
Everything gets read by a central computer that runs data collection software. It can do alerts (pages, email).
Alternatively, you can do local storage, typically to an SD card. Omega sells those too, but you can get cheaper versions from other manufacturers.
Think about communications and data collection. SD cards are easy, but labour intensive. Wireless we found really unreliable in an environment with lots of electronic noise from small machines and engines. Putting ethernet drops near every fridge turned out to be cheap (~$100/drop), cheaper even than a custom wiring solution and long-term has proven really easy to manage. It's standard, so we have lots of equipment choices.

Response by poster: bonehead - is the data collection software provided by Omega or are you using something else?

What odinsdream said. We read the data directly into an excel sheet.
