Waterproof wireless sensor Dragino LSN50-V2 LoRa of large action

LoRa sensor node LSN50 is a long-range LoRa sensor node. It is designed for outdoor use and is powered by a 4000mA or 8500mA Li/SOCl2 battery for extended use. The LSN50 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.

The wireless part of the LSN50 based on the SX1276/SX1278, which allows the user to send data and reach extremely long distances at low data rates. It provides ultra-long-range spread-spectrum communication and high resistance to interference, minimizing current consumption. It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, etc.

Part of the LSN50 microcontroller uses ST’s STM32l0x chip, STML0x are ultra-low-power STM32L072xx microcontrollers that combine the connectivity power of a universal serial bus (USB 2.0 chipless) with a high-performance 32-bit ARM® Cortex®-M0+ RISC core running at 32 MHz, a memory protection unit (MPU), high-speed on-board memory (192 Kbytes of flash memory for programs, 6 Kbytes of EEPROM data and 20 Kbytes of RAM), as well as a wide range of advanced I/O and peripherals.

LSN50 is an open source product, it is based on the STM32Cube HAL drivers and many libraries available on the ST site for rapid development.
