In stock (>5 pcs)

All-in-one pack for monitoring of air quality (0 to 60 000 ppb concentration of volatile organic compounds), Atmospheric pressure (30 000 to 110 000 Pa), Air humidity (%RH), and Temperature (-30 to +70°C).  Sensor probe on 3m long cable. NB-IoT connectivity with 3-years prepaid SIM card included. The Free or paid portal is available.

Portal sends or displays alerts when air quality is low (air-conditioning system, residential buildings, schools, etc.). The atmospheric pressure values are useful for weather forecasting or for detecting loss of pressure in positive or negative pressure rooms.

The device is connected to the internet with NB-IoT (NarrowBand IoT) technology (provided typically by an LTE operator). The device is powered by the wall-plug power adaptor or by the internal battery.

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 too low. Portal will alert you also when an internet connection with a device is lost or the external sensor is disconnected.

Paid portal
www.sensdesk.com - 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)
  • 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)
  • Alert can trigger action on another connected device or system (ventilation, air-condition, etc. - add SD-2xOut or NB-2xOut to the system or integrate into 3rd party SW (SNMP / XML Open API)

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.
  • 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 NB-IoT (NarrowBand IoT) technology by Mobile operator
  • The external antenna can be replaced by bigger / more sensitive remote antenna.
  • External sensor (3m) CO2 1W-UNI (300 - 40 000 ppm), (Temperature (-0 °C to +50 °C) and Relative Humidity (0-95% RH)
  • Up to 4 sensor values (in total) measured by external Sensors can be connected to the device.
  • Included sensor (probe): CO2, Temperature, Humidity (3 sensor values)
  • External RJ11 sensors can be placed up to 60 meters from the main unit (RJ11 prolong cabling).
  • Power for NB-2x1Wire device by External power adaptor/internal battery
  • International Wall plug power adaptor included (EU, UK, US power sockets included)

The device has to be connected to the public internet to one of SensDesk technology-based portals (HWg-cloud / SensDesk.com / other).

  • The device can be pre-configured. Just click it to the power & LAN 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)
  • Periodical PDF or CSV reports (paid service only)
  • Voice call and SMS alerts (paid service only)

Solution Pack contains:

  • NB-2x1Wire Unit for connection to the web portal
  • Vodafone NB-IoT SIM card with 3-years pre-paid connectivity subscription
  • Sensor THPVoc 1W-UNI: Combined sensor for monitoring of Air quality (VOC, 0 – 60 000 ppb), Atmospheric pressure (30 000 to 110 000 Pa), Temperature (-30 to +70 °C), Humidity (0-100 %RH, Relative Humidity),


Can be interesting for you:

  • If you do have LAN/Wi-Fi connectivity on the site, use our SD-IoT package with similar features and an internal battery.
  • Alert to any Alarm state can be reported also by switching ON external light/siren. Usu the LAN/Wi-Fi or NB-IoT device with relay output.
