18 == 1.1 What is SW3L-NB NB-IoT Flow Sensor ==
19
20
21 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**.
22
23 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.
24
25 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**.
26
27 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.
28
29 SW3L-NB (% style="color:blue" %)**supports BLE configure **(%%)and(% style="color:blue" %)** OTA update**(%%) which make user easy to use.
30
31 SW3L-NB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long-term use up to several years.
32
33 SW3L-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.

729 To save battery life, SW3L-NB will sample Water Flow data every 15 minutes and send one uplink every 2 hours. So each uplink it will include 8 stored data + 1 real-time data. They are defined by:
730
731 * (% style="color:#037691" %)**AT+TR=900**   (%%) ~/~/ The unit is seconds, and the default is to record data once every 900 seconds (15 minutes, the minimum can be set to 180 seconds)
