SW3L-004 - LoRaWAN Outdoor Flow Sensor for water usage monitoring - DN15/450 pulse/L

The Dragino SW3L 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.

SW3L is powered by 8500mAh Li-SOCI2 battery, It is designed for long term use up to 10 years. (Actually Battery life depends on the use environment, update period.)

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

Each SW3L is pre-load with a set of unique keys for LoRaWAN registration, register these keys to 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.
