22 == 1.1 What is SW3L-NB NB-IoT Flow Sensor ==
23
24
25 The Dragino SW3L-NB is a (% style="color:blue" %)**NB-IoT Flow Sensor**(%%). It detects water flow volume and uplink to IoT server via NB-IoT network. User can use this to (% style="color:blue" %)**monitor the water usage for buildings**.
26
27 The SW3L-NB will send water flow volume every 20 minutes. It can also detect the (% style="color:blue" %)**water flow status and send Alarm**(%%), to avoid the waste for water usage such as broken toilet case.
28
29 SW3L-NB is designed for both indoor and outdoor use. It has a weatherproof enclosure and industrial level battery to (% style="color:blue" %)**work in low to high temperatures**.
30
31 SW3L-NB supports different uplink methods including (% style="color:blue" %)**MQTT, MQTTs, UDP & TCP**(%%) for different application requirement, and support uplinks to various IoT Servers.
32
33 SW3L-NB (% style="color:blue" %)**supports BLE configure **(%%)and(% style="color:blue" %)** OTA update**(%%) which make user easy to use.
34
35 SW3L-NB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long-term use up to several years.
36
37 SW3L-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.

209
210 The DDS45-NB is equipped with a NB-IoT module, the pre-loaded firmware in DDS45-NB will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module.  The NB-IoT network will forward this value to IoT server via the protocol defined by DDS45-NB.

621 == 6.2 Can I use DDS45-NB in condensation environment? ==

624 DDS45-NB is not suitable to be used in condensation environment. Condensation on the DDS45-NB probe will affect the reading and always got 0.

627 = 7. Trouble Shooting =
628
629 == 7.1 Why does the sensor reading show 0 or "No sensor" ==
630
631
632 ~1. The measurement object is very close to the sensor, but in the blind spot of the sensor.
633
634 2. Sensor wiring is disconnected
635
636 3. Not using the correct decoder

639 == 7.2 Abnormal readings The gap between multiple readings is too large or the gap between the readings and the actual value is too large ==
640
641
642 1) Please check if there is something on the probe affecting its measurement (condensed water, volatile oil, etc.)
643
644 2) Does it change with temperature, temperature will affect its measurement
645
646 3) If abnormal data occurs, you can turn on DEBUG mode, Please use downlink or AT COMMAN to enter DEBUG mode.
