Cold Storage Monitoring

Read how to improve food safety and automate compliance reporting with continuous refrigerator/freezer temperature monitoring, real time alerts and digital logs.


Sensor devices


Wireless mesh network


Gateway to RedBoard


RedBoard Cold Storage Manager


Real-time alerts

How it works

  1. Battery operated sensor devices are attached to the inside of the fridge or freezer. They report on temperature, humidity, door, light and compressor status in real-time.

  2. Sensor devices automatically form a mesh network and report status to a cellular or WIFI gateway. No wired infrastructure such as access points required.

  3. The gateway transmits the data to the RedBoard Cold Storage Manager.

  4. The RedBoard Cold Storage Manager transforms data into insights, visualizes them on dashboards and optionally interfaces to legacy data systems.

  5. The operator receives real-time alerts on a smartphone app. In addition, he can configure sensor devices locally and read its data in case of service interruptions.
