Digi Honeycomb
Digi Honeycomb probe for automated food temperature monitoring

DIGI FRESHPROBE

Digi FreshProbes are an integral part of the Digi FreshTemp automated food temperature monitoring system. The handheld wireless probe sends instant temperature readings to your Bluetooth-enabled tablet or phone to measure and record temperatures in hot and cold holding environments.

Digi FreshProbes are portable and work anywhere you need immediate temperature data. Measurements are taken in seconds and displayed in the Digi FreshTemp app, eliminating the time, labor and effort to manually collect and log data the old-fashioned way with paper and pencil.

Digi Honeycomb sensor for automated food temperature monitoring

DIGI FRESHSENSE

Digi FreshSense wireless temperature sensors are easy to use and part of the complete Digi FreshTemp automated food temperature monitoring solution. Temperature data is collected, viewed and managed through the Digi FreshTemp app. FreshSense Sensors have an operating range of -40° C to 85° C (-40° F to 180° F), with a communication range of up to 1 mile in ideal conditions. The sensors come active when shipped and temperatures are captured and logged as soon as the companion Digi FreshGateway is activated and the two devices automatically pair up.

Digi FreshTemp collects temperature data 24/7, with customized alerts when temperatures fall out of range to protect your inventory when refrigerators and walk-in freezers suffer an outage. Additional sensing options, such as humidity and vibration, can help ensure the integrity of your equipment to suit all your in-store cold chain monitoring needs.

FreshSense wireless temperature sensors are enclosed in a durable and easy to clean plastic enclosure to maintain monitoring accuracy in food handling environments. The sensors use Zigbee® wireless technology to broadcast real-time data to Digi FreshGateways to be stored and processed.

Digi Honeycomb gateway for automated food temperature monitoring

DIGI FRESHGATEWAY

Digi FreshGateway is the central hub of the automated food temperature monitoring system. Once the temperature reading is confirmed, the recorded data is logged and sent to the Wi-Fi FreshGateway that processes and saves it to the Cloud for easy, up-to-the-minute compliance reporting and long-term storage.

As soon as the Digi FreshGateway is powered up it will automatically pair with all the Digi FreshSense sensors within range. Temperature data is reported every ten minutes and is securely transmitted to the Digi FreshTemp cloud-based temperature monitoring app.

Digi Honeycomb App

DIGI FRESHTEMP

The Digi FreshTemp mobile and desktop temperature monitoring and task management app receives temperature readings from the Digi FreshSense sensors via the Wi-Fi connected Digi FreshGateway and from Digi FreshProbes via Bluetooth. The app automatically stores data for easy access to compliance logs and provides viewable trends in the collected data for better monitoring insights.

When food temperatures fall out of range, for any reason, the app sends out automated real-time alerts to key user handheld devices so that they can take immediate corrective action. In the event of a power outage, the FreshGateway continues to collect rolling data from the sensors and logs it into the Cloud where it can be readily accessed by employees for both spoilage assessment and compliance reporting.

Temperature data is accessed via the Digi FreshTemp desktop or mobile app and belongs entirely to the customer – stored securely, backed-up regularly, and not shared with or sold to third parties in any way.
