LSN50 LoRa Sensor Node is designed for outdoor use (IP66) and powered by a 4000mAh Li/SOCl2 battery for long term use.
LSN50 wireless part is based on SX1276/SX1278. It allows the user to send data and reach extremely long ranges at low data-rates. LSN50 MCU part uses the ultra-low-power STM32L072xx microcontroller with the high-performance ARM Cortex-M0+ 32-bit RISC core operating at a 32 MHz.
LSN50 is open source and based on the STM32Cube HAL drivers. Libraries can be found in ST site for rapid development. With a USB to serial adapter, you can use AT commands and the free STM32 Flash loader to program the LSN50.
The Li/SOCI2 battery will last for many years. A calculation example shows that it will run for more than 7 years with sensor values transmitted via LoRa every 15 minutes.
