HW-group NB-2x1Wire TSET – IoT water protection solution for server rooms and industry
HW-group NB-2x1Wire TSET
Water leaks are a significant risk for data centers, server rooms, and industrial environments. The NB-2x1Wire TSET from HW-group provides an innovative IoT-based solution that integrates up to four 1-Wire or 1-Wire UNI sensors, enabling protection against water ingress. The device serves as a central monitoring unit with Narrowband IoT (NB-IoT) connectivity, making it ideal for sites without LAN or Wi-Fi infrastructure.
The set includes a 3-year NB-IoT SIM card, a temperature sensor, and a power adapter, making it a ready-to-use starter kit for remote monitoring of environmental and water parameters.
Water Leakage Protection via 1-Wire Sensors
The NB-2x1Wire TSET supports WLD sensors and flood detectors that can register even small amounts of conductive liquid. These sensors can be installed in critical areas such as raised floors, pipelines, or technical rooms. When moisture is detected, real-time alerts are sent via e-mail or push notification. In combination with an SMS gateway, SMS and voice call notifications can also be configured.
Key Features
- 1-Wire sensor integration: up to 4 sensors (temperature, humidity, voltage, CO2, VOC, light, water leakage detection)
- IoT connectivity: NB-IoT for secure and energy-efficient data transfer
- Data logging: stores up to 250,000 readings, export via HWg-PDMS to Excel
- Power supply: internal battery (up to 3 years lifetime) or external 5V adapter
- Alerts: e-mail, HWg-Push, optional SMS/voice via HWg-SMS-GW3
- Protocols: NB-Push, CoAP, SNMPv3, MQTT, XML
- Robust housing: metal, IP40, suitable for DIN-rail mounting
Typical Applications
- Server rooms & data centers: leak detection under raised floors or near air conditioning systems
- Warehouses & cold storage: protection against moisture damage in pharma, food, or electronics
- Smart buildings: leak detection in IoT-enabled facilities
- Industrial plants: integration of sensors for water and environment monitoring
- Offices & schools: alerts for burst pipes or uncontrolled water ingress
Integration & Portals
Through SensDesk or HWg-Cloud, values and alarm states can be managed centrally. Graphical displays, PDF reports, and multi-user accounts simplify administration. Open interfaces such as SNMP, MQTT, and XML ensure seamless integration into SCADA and IoT environments.
Alarm Options
- E-mail/push: direct notification to up to 5 recipients
- SMS/voice: possible via optional SMS-GW3 gateway
- Custom rules: e.g., “send alarm if moisture is detected under the raised floor”
Versions & Package Contents
- NB-2x1Wire TSET: complete package including SIM card, power adapter, battery, and 3 m temperature sensor
- Accessories: WLD sensors, flood detectors, additional 1-Wire sensors
Summary
Can the NB-2x1Wire TSET detect water leaks early?
Yes, by connecting WLD sensors or flood detectors, it is specifically equipped for leakage detection.
How are alarms reported?
By default via e-mail or push to the SensDesk portal, and optionally through an SMS/voice gateway.
Is the system suitable for remote locations?
Yes, thanks to NB-IoT wireless connectivity, operation without LAN/Wi-Fi is possible – making it ideal for isolated technical rooms.
