SW3L NB-IoT LTE CAT-M Outdoor Flow Sensor
The Dragino SW3L is a NB-IoT or LTE CAT-M Flow Sensor. It detects water flow volume and uplink to IoT server via NB-IoT or CAT-M network. User can use this to monitor the water usage for buildings.
The SW3L will send water flow volume data. 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.
SW3L supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.
SW3L supports BLE configure and OTA update which make user easy to use.
SW3L is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use for up to several years.
