SW3L-LS DN25 G1 LoRaWAN Flow Sensor 868MHz with Solar

The SW3L-LS from Dragino is an advanced LoRaWAN flow sensor, optimized for efficient monitoring of water consumption in various environments. This sensor, supported by a combination of solar power and an additional battery, ensures reliable and long-lasting operation, ideal for autonomous outdoor use. Besides the traditional battery supply, the SW3L-LS uses a solar cell for power supply, reducing the need for frequent maintenance. Equipped with a powerful 48 MHz ARM microcontroller, 256KB Flash and 64KB RAM, this sensor provides the necessary computing capacity for demanding applications. The simple configuration via BLE and the ability to receive OTA updates greatly simplify the management and maintenance of the system. With the SX1262 LoRa Core, the sensor offers an exceptionally wide range and high interference immunity, making it the ideal choice for a variety of IoT applications. Each sensor is equipped with a set of unique keys for LoRaWAN registration, which are registered on a local LoRaWAN server. The sensor automatically connects upon powering on, provided there is network coverage.
