If you are responsible for self-control and food safety in your kitchen, you can use ThermITs digital wireless electronic temperature logging system.
Suppose you have, e.g., two walk-in coldrooms, and four refrigerators in your kitchen. In that case, you will need two Digital wireless temperature sensors with a long antenna and three Digital wireless temperature sensors with shorter antennas and some holders.
To get the sensor signals up in the cloud to the servers so you can follow and see the temperatures, you also need a GSM Main Module (Gateway)
