What is NarrowBand technology and how it can help in your monitoring ?
NB Devices
The NB-xxx family are IoT Monitoring Simple Devices for wireless remote monitoring using the NB-IoT network. Devices can monitor external sensors of Temperature, Humidity, Voltage, Current, DI states / pulses, WLD sensing cable, and other sensors. NB-2xOut can also control external devices (Relay DO).

Monitoring on remote locations can be installed in just a few clicks and you can get your data in minutes. The NB-IoT (NarrowBand) network-connected devices can be battery-powered with a battery life of 2 years or with an external power supply. The SIM card with 3 years subscription is included in the standard product version. NB-xxx devices require a SensDesk Technolgoy portal (free or paid version) where you can monitor and control your entire system. portal is pre-configured. Devices can be migrated / adopted to any SensDesk Technology based portal
4 sensor values to the portal (NarrowBand IoT)

4 external RJ11 sensors values to the portal (Temperature, Relative Humidity, Current, ...). Internal battery, NB-IoT cellular network connectivity, portal required.
2x DI (Digital Input) for external door / smoke detectors. Internal battery, NB-IoT cellular network connectivity, portal required.
2x DO (Relay Output) controlled from the portal. Internal battery, NB-IoT cellular network connectivity, portal required.
1x Water Leak Detection zone (sensing cable) to the portal. Internal battery, NB-IoT cellular network connectivity, portal required.
Sensors & Detectors
70 precise Sensors and Detectors for every application. The Sensors measure
a continuous analog value, use only original accessories from the HW group (except Pt100, Pt1000 ports
or 4-20mA industrial sensor Analog Inputs). Any Detector with relay output can be connected to DI (Digital
Inputs) ports.
Portal Solution

All IoT Monitoring Devices have to be connected to any SensDesk Technology-based portal (SaaS) in order to work properly.

The SensDesk Technology is a portal solution from the HW group to manage remote sensors and devices (only for HW group products). Portals offer a central overview of all the values and provide a variable combination of features like sending the alarms, reporting, history records, outputs into the Open API, etc.
