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

The SW3L-LB/LS will send water flow volume every 20 minutes by default. It can also detect the water flow status and send Alarm, to avoid the waste for water usage such as broken hose / pipe

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

The LoRa wireless technology used in SW3L-LB/LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

SW3L-LB/LS supports BLE configure and wireless OTA update which make user easy to use.

SW3L-LB/LS is powered by 8500mAh Li-SOCI2 battery or solar powered + Li-ion battery, it is designed for long term use up to 5 years.

Each SW3L-LB/LS is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

Default FW in AS923, but it support US915, AU915 and all 900MHz Frequency by loading different FW, it could also support 868MHz if loading 868MHz FW, but there will be slight 0.5-1dB loss here due to different antenna
