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.

890
891 == 6.2 Can I use SW3L-NB in condensation environment? ==
892
893
894 SW3L-NB is not suitable to be used in condensation environment. Condensation on the SW3L-NB probe will affect the reading and always got 0.

897 = 7. Trouble Shooting =
898
899 == 7.1 Why does the sensor reading show 0 or "No sensor" ==
900
901
902 ~1. The measurement object is very close to the sensor, but in the blind spot of the sensor.
903
904 2. Sensor wiring is disconnected
905
906 3. Not using the correct decoder
907
908
909 == 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 ==
910
911
912 1) Please check if there is something on the probe affecting its measurement (condensed water, volatile oil, etc.)
913
914 2) Does it change with temperature, temperature will affect its measurement
915
916 3) If abnormal data occurs, you can turn on DEBUG mode, Please use downlink or AT COMMAN to enter DEBUG mode.
917
918 downlink command: (% style="color:blue" %)**F1 01**(%%), AT command: (% style="color:blue" %)**AT+DDEBUG=1**
919
920 4) After entering the debug mode, it will send 20 pieces of data at a time, and you can send its uplink to us for analysis
