All-in-one pack for remote monitoring temperature (-30°C to +60°C) in fridges or freezers. Using an external temperature sensor (probe) on a flat cable.  The flat (ribbon) cable of the sensor can be routed through the door seal. This solution can guard temperature (temperature range) for food storage (HACCP), medical supplies, wineries, etc. NB-IoT connectivity with 3-years prepaid SIM card included. The free or paid portal is available.

The device is connected to the internet with NB-IoT (NarrowBand IoT) technology (provided typically by an LTE operator). The device is powered by a wall-plug power adaptor or from the internal battery. Portal alerts you and your colleagues when the temperature in the fridge is too low (too high), or the sensor is disconnected.

Other sensors or detectors can extend the pack with RJ11 (cryo, light, humidity, etc.) 


Detailed information

Product detailed description

Current sensor values and alerts are available from anywhere and can be displayed on mobile phones, tablets, notebooks... Even the free portal ( displays graphs and sends E-mail alerts/alarms when monitored values are too high or low. Portal will alert you also when an internet connection with a device is lost, or an external sensor is disconnected.  

Mobile App is available for your mobile phone, even for the tablet display installed on the wall.

One of the HW-group web portals is required to use the Pack to send alerts and access data from HW-group devices and connected sensors.

2 portal options by HW-group:

  • Free portal - HWg sensors & devices in the cloud, free service with email alerts up to 20 devices connected to one user account.
  • Paid portal - Monitoring and Alerting system in the cloud. PDF reports, SMS & Voice call alerts, graphs, multigraphs, and up to 2 years of data history. Paid as a one-year subscription plan.

Alert options (when every second matters):

  • Voice-Call alert (paid service)
  • SMS (standard text message (paid service)
  • E-mail alerts within few seconds since value out of safe-range (email can be repeated every 30 minutes if alarm still valid or delayed if values are still too high after 30 minutes)
  • Alarm escalation based on sensor value can alert another E-mail / mobile phone number if needed.
  • Visual or Audio Alerts: Local red light or alert on a tablet on the wall or even siren (paid service)

Alerts can be triggered by:

  • Sensor value (out of Safe Range / Notice range).
  • The sensor disconnected from the device.
  • Device powered from External power / internal battery change
  • Device power failure (alerts even before sensor values are out of safe range).
  • The device is not found/disconnected from the Internet.

Current sensor values can be displayed:

  • Web of the portal (compatible with mobile phones)
  • Mobile phone App (coming soon)
  • Android / iOS-based Tablet installed on the wall (displaying selected sensor values only)
  • 3rd party SW (SNMP / XML Open API)

Solution features:

  • Connectivity by LAN (Ethernet) or Wi-Fi (External antenna possible)
  • External sensor Temp-1Wire-Flat 3m (-30°C to +60°C)
  • Up to 4 sensor values (in total) measured by external Sensors can be connected to the device.
  • Included sensor (probe): Temp-1Wire-Flat 3m (-30°C to +60°C)
  • External RJ11 sensors can be placed up to 60 meters from the main unit (RJ11 prolong cabling).
  • Power for SD-2x1Wire device from PoE / External power adaptor
  • International Wall plug power adaptor included (EU, UK, US power sockets included)

Solution extension possibilities:

    • Additional RJ11 sensors can be connected to the device (3 additional sensor values).
    • You can connect additional RJ11 sensors (max 60m distance) of Temperature, Relative Humidity, Light intensity, etc...

NB device has to be installed in the area with Vodafone NB-IoT signal coverage. The device has to be adopted by one of SensDesk technology-based portals (HWg-cloud / / other).

  • The device can be pre-configured. Just install the sensor + power adaptor on the remote site.
  • Sends E-mail alerts when values are out of the set range
  • Displays current values on the mobile app (Wall installed tablet)
  • History / Graph (chart) with values (10 / 30 / 365 / 730 days)
