NB Devices product family

NB Devices is a family of environment monitoring products that use the Narrowband (NB-IoT) mobile network. All products feature robust design, battery-powered operation, and seamless integration with the SensDesk IoT portal. All devices include a 3V alkaline CR123A battery that allows continuous operation for about 3 years (depending on the device type, application and connected sensors).

Overview of NB Devices

• NB-2x1Wire – A device for connecting thermometers, hygrometers, or other sensors via the 1-Wire bus. Allows connecting two 1-Wire or 1-Wire UNI sensors to measure up to 4 quantities simultaneously.
• NB-2xIn – A device for connecting a door or window contact, a PIR motion detector or a smoke or gas detector with a dry contact output. Allows connecting 2 independent detectors. Inputs can feature pulse counters for connecting energy meters with S0 output; however, external power is needed for reliable deployment.
• NB-WLD – Water leak detector with a moisture-sensing cable. Allows connecting 1 sensing cable of up to 60m length.
• NB-2xOut – A module with 2 relay outputs controlled from the SensDesk portal over the NB-IoT network.

Shared features of the NB-IoT product family

• Robust metal design, 67 × 78 × 33 mm
• External antenna, SMA connector
• 4FF (nano SIM) holder
• LED indicator
• Plug&Play – connect power or remove the insulating strip and the device is immediately available in the portal
• All settings (data upload period, safe ranges) are configured in the portal
• Battery state appears in the portal as another sensor
• Powered from a 5V adapter or the built-in replaceable CR123A battery

For specifics of individual devices, including any differences in the measurement period, battery life and so on, see the respective device page.

Measurements and data upload

Measurement and data upload period
The period for logging the measured values and uploading them to the portal is configured automatically via the portal, separately for operation with an external power source and battery-powered operation. At the time of this writing, the following values were valid for the SensDesk portal:

External power

• Logging period (measuring, storing values in the internal memory): 5 minutes
• Data upload period (connecting to the portal and uploading all logged values): 1 hour
• Check period (NB-2xOUT brief query for output state changes): 10 minutes

Battery power

• Logging period (measuring, storing values in the internal memory): 15 minutes
• Data upload period (connecting to the portal and uploading all logged values): 10 hours
• Check period (NB-2xOUT brief query for output state changes): 1 hour

Only the server administrator may change these periods. In justified cases, individual changes can be agreed with the server administrator. However, keep in mind that if the periods are shortened, battery life may be very negatively impacted. In any case, the data upload period cannot be shorter than 60 minutes and the logging period shorter than 5 minutes.

Periodic and non-periodic reading of sensors
Sensors values are regularly read in the fixed Log Period, which is configured via the SensDesk portal. However, in addition to the periodic reading, the values can be also read if the following happens:

1. The device is powered up by connecting the battery or an external power supply
2. The button is pressed
3. If the SafeRange is exceeded at the moment of periodic reading, the measurement is repeated after the Delay interval

Periodic and non-periodic data upload
Sensor values are uploaded to the server periodically in the fixed period, which is configured via the SensDesk portal. However, in addition to the periodic upload, data can be also uploaded if the following happens:

1. SIM card is inserted
2. Device power is connected or changed
3. The button is pressed
4. SafeRange is exceeded (if the Delay is set, then only after the Delay elapses)

SafeRange – range of allowed values
SafeRange is configured in the SensDesk portal separately for each sensor. Whenever the measured value is outside of this range, a message is sent. (However, keep in mind that in order to extend battery life, sensors are only read in the Log period. With the exception of SD-2xIN, sensors are NOT read at other times.) If a Delay is set together with the SafeRange, the repeated measurement is performed at the next Log period, and an Alarm is raised only if the repeated measurement is also out of the SafeRange.

Hysteresis / Idle range
The Hysteresis setting defines a tolerance band for suppressing alarm alerts. The function prevents multiple alarm alerts if the reading oscillates around the specified threshold. The range is configured independently for each sensor.

The figure demonstrates two cases. Without the hysteresis idle range of 5 °C, the alarm raised in point 8 would end in point 9; however, the hysteresis function keeps the alarm active until the temperature reaches the upper limit of the tolerance band (point 10): 5 °C + (–15 °C) = –10 °C.

• Hysteresis = 5°C – The unit sends 3 e-mail (SMS) messages. Alarm active in points 0..4, 8..10, 12 and beyond.
• No hysteresis (0°C) – The unit sends 8 e-mail (SMS) messages. Alarm active in points 0..1, 2..3, 8..9, 12..13, 14 and beyond.

In determining when the Alarm ends, the Hysteresis value applies. The end of an Alarm is only notified when the measured value is well within the SafeRange. However, the value is only read according to the Log Period.

Alarm status notification based on a Delay value:

• Blue: Delay = 0
• Yellow: Delay is non-zero

To increase battery life, be careful when setting the SafeRange and Hysteresis values.

Description of HW elements

LED indicator (Status) The blue LED gives a quick status indication for debugging and troubleshooting. It can indicate these states:

• Short flash – reading of sensors and inputs
• Rapid flashing – registration to the NB-IoT network
• Continuously on – communication over the NB-IoT network, data transfer

When power is connected to the device, the indicator briefly lights up to indicate modem initialization and 1-Wire sensor detection. Then, it quickly flashes as the device connects to the network, and lights up whenever the device communicates with the portal. It also briefly flashes when the 1-Wire sensors or the WLD cable state are being read.

Setup button
The button is used to send values to the portal immediately and to detect sensors.

• Press – sensors are detected and data are sent to the portal
• Press for longer than 10 s – reset to factory defaults

Setting up the device

1. Attach the external antenna

2. Connect 1-Wire sensors (NB-2x1Wire only)

3. Insert SIM card

4. With a slight force, pull out the insulating strip that insulates the battery from the contacts

5. Connect the external power supply and wait until the device connects to the operator’s network (i.e. until the blue LED turns off). Depending on the network and device configuration, this can take up to 20 minutes (when the device is first connected to an operator’s network, including in a new country or region). During this time, do not disconnect external power to avoid battery drain.

NB-Devices models and their specific features

NB-2x1Wire

Measurement hub for connecting thermo-meters, humidity sensors or other sensors via the 1-Wire bus. Allows connecting two 1-Wire or 1-Wire UNI sensors (one per port) to measure up to 4 quantities simultaneously.

Sensors are detected whenever power is connected to the device or the Setup button is pressed.
The device can be powered from an external 5V adapter, from its internal battery, or using a combination of these. With a single connected Temp-1Wire IP67 temperature sensor and the default sensor reading and data upload periods, the battery lasts up to 3 years. When using 1-Wire UNI sensors, either the sensors or the NB-2x1Wire device should be powered from an external adapter because such sensors significantly reduce the battery life.

A device for connecting a door or window contact, a PIR motion detector or a smoke or gas detector with a dry contact output. Allows connecting 2 independent detectors. Inputs feature pulse counters for connecting energy meters with an S0 output. Due to high energy requirements of S0 outputs, external power is required for reliable pulse counting. Otherwise, reliable operation cannot be guaranteed.
The input mode (Alarms or Counters) can be changed in the digital input configuration at the SensDesk portal using the “Alarm level” parameter.
If the “Not Defined” option is selected, the input is in pulse counting mode and its state is only uploaded in the regular data upload period. Only changes longer than 20 ms are detected.

When Alarm level = 1 or Alarm level = 0, the input is in the Alarm mode. The input state is uploaded in the regular data upload period as well as whenever there is a change. To comply with the transmission limit, the device will send no more than 3 alarms per 10 minutes. Frequent state changes can have a significant impact on battery life. For battery operation, cables should be as short as possible to avoid false pulses. For operation with an external power adapter, the cable should be at most 50 m long.
The default mode is the counter mode (i.e. Alarm level = Not defined).
When an input is activated (contact closed) and the device is powered from an external adapter, the respective green LED lights up. The LEDs are inactive on battery power.

NB-WLD

Water leak detector with a moisture-sensing cable. Allows connecting 1 sensing cable of up to 65m length, or extend it by up to 20 m.

The flood detection is performed every 5 minutes and the estimated battery life are 4 years.
If the cable is flooded or disconnected and the device is powered from an external adapter, the red LED lights up. The LED is inactive on battery power.

NB-2xOUT

A module with 2 relay outputs controlled from the SensDesk portal over the NB- IoT network. To reduce consumption, the device features two latching relays. For increased reliability, the relays are energized repeatedly every 10 minutes. The device is not suitable for mobile applications. On battery power only, the estimated battery life are 2 years.
When an output is closed and the device is powered from an external adapter, the respective yellow LED lights up. The LEDs are inactive on battery power.
