The Dragino LSN50-V2 long-range LoRa wireless sensor node is waterproof

SN50V3-LS The LoRaWAN Sensor Node is a long-range LoRa sensor. It is designed for outdoor use and is powered by 8500 mAh lithium-ion battery or solar-powered lithium-ion battery for long-term use. The SN50V3-LB/LS is designed to make it easier for developers to rapidly deploy industrial-grade LoRa and IoT solutions. It helps users turn an idea into a practical application and make the Internet of Things a reality. It’s easy to program, build and connect your stuff everywhere.

Wireless part SN50V3-LS based on the SX1262, which allows the user to send data and achieve extremely long distances at low data rates. It provides ultra-long-range spread-spectrum communication and high resistance to interference, minimizing current consumption. It is aimed at the application of professional wireless sensor networks, such as irrigation systems, smart metering, smart cities, etc.

The SN50V3-LS has a powerful 48 MHz ARM microcontroller with 256 KB of flash memory and 64 KB of RAM. It has multiple I/O pins for connecting to various sensors.

The SN50V3-LS has built-in BLE module , the user can configure the sensor remotely using a mobile phone. He also supports OTA update via private LoRa protocol for easy maintenance.

The SN50V3-LS is the 3rd generation of Dragino’s LSN50 series universal sensor node. It an open source project and has a mature LoRaWAN stack and application software. The user can use the pre-loaded software for their IoT projects or easily customize the software for different requirements.
