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

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

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

The sensor node uses Quectel BC660K-GL Multi-band LTE Cat NB2 module which can be used in most European countries. It has a card slot for an NB-IoT SIM card. 

SW3L-NS supports BLE configure and OTA update which make user easy to use.

SW3L-NS is powered by a rechargeable battery and a solar cell for continuous use. It has an external antenna and a waterproof IP66 enclosure.
