["DRAGINO water flow meter G1/2'' / DN15 The Dragino SW3L-LB is a LoRaWAN flow sensor. It detects the water flow rate and connects to the IoT server via the LoRaWAN network. The user can use it to monitor water consumption in buildings. The SW3L-LB sends the water flow rate every 20 minutes. It can also detect the water flow status and send an alarm to avoid water waste, such as a broken toilet tank. SW3L-LB is suitable for both indoor and outdoor use. It features a weatherproof housing and an industrial-grade battery for use in low to high temperatures. The LoRa wireless technology used in the SW3L-LB allows the device to send data and achieve extremely long ranges at low data rates. It offers spread spectrum communication with extremely long range and high interference immunity with minimal power consumption. SW3L-LB supports BLE configuration and over-the-air OTA updates, making it easier for users to use. SW3L-LB is powered by an 8500mAh Li-SOCI2 battery and is designed for long-term use of up to 5 years. Each SW3L-LB is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN servers and it will automatically connect after power on", "LoRaWAN v1.0.3 Class A protocol", "Bands:CN470/EU433/KR920/US915/EU868/AS923/AU915/IN865/RU864", "Ultra-low power consumption", "Upload the water flow rate", "Water consumption monitoring", "AT commands for changing parameters", "Supports datalog function", "Supports Bluetooth v5.1 and LoRaWAN remote configuration", "Supports wireless OTA update of firmware", "Uplink at regular intervals and open/close event", "Downlink to change configuration", "8500mAh Li/SOCl2 battery (SW3L-LB)", "Flow sensor", "Water control", "Toilet Flow Sensor", "Monitoring of wastewater", "1 x water flow meter G1/2'' / DN15 · SW3L-LB-EU868-004"]
