Dragino SW3L-NB NB-IoT Water Flow Sensor

The Dragino SW3L-NB is a NB-IoT Water Flow Sensor. It detects water flow volume and uplinks to the IoT server via the NB-IoT network. Users can use this to monitor the water usage for buildings.

The SW3L-NB will send water flow volume every 20 minutes. It can also detect the water flow status and send an Alarm, to avoid waste for water usage such as broken toilet case.

SW3L-NB is designed for both indoor and outdoor use. It has a weatherproof enclosure and industrial-level battery to work in low to high temperatures.

SW3L-NB NB-IoT Flow Sensor supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.

SW3L-NB supports BLE configure and OTA update which make users easy to use.

SW3L-NB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

SW3L-NB has an optional built-in SIM card and default IoT server connection version. Which makes it work with a simple configuration.
