Selection of temperature sensors for refrigerators/freezers with data logging (or remote reading)

Hi.

I need to set up 12 temperature sensors in the shop.

Some will be in fridges, freezers.

Would you please advise what devices to choose for this, so as not to bankrupt.

The sensors in fridges/freezers would preferably have a probe released, so that the device is attached somewhere on the back and only the soda is let inside.

I need each sensor to take a reading, say every 30 minutes and save in a common database (some "ordinary" under which I will be able to connect to some tool for reporting and monitoring, to send an alert in case of something) or to allow remote reading (then I will write an automat to read the temperature and save in the database)


Thank you in advance .

What is your budget? Have you looked at Simex and their SimCorder Soft app.

Budget unspecified, as I don't know how much you need to spend (what order of magnitude it is anyway).

I haven't looked, but I'll look right away - thank you.
