["The LSN50 LoRa Sensor Node is a LoRa Sensor Node with a large range. Er ist für den Außeneinsatz koncept und wird für den Zeiteinsatz mit einer Li/SOCl2-Batterie beutritten. LSN50 wurde entwickelt um Entwickler zu faciliteren schenlen Einsatz von LoRa und IoT Lösungen auf industriale Level. It helps the user to turn the idea into a practical application and let the Internet of Things become reality. Es ist einfach, Ihre Dinge zu programmieren, zu erstellen und überall anzuschließen. The wireless part of the LSN50 is based on SX1276/SX1278 and enables the user to send data and extremely large reach at low data rates. It offers spread-spectrum communication with ultra-high reach and high interference resistance at minimal power consumption. It is aimed at professional wireless sensor network applications such as irrigation systems, intelligent counting systems, intelligent cities, smartphone recognition, building automation, etc. ab. Der LSN50-MCU-Teil verwendet den STM32l0x-Chip von ST, STML0x is der Ultra-Low-Power-Microcontroller STM32L072xx, der die Konnektivitätsleistung des universalen serialen Busses (USB 2.0 crystal-free) mit dem high-performance 32-Bit-RISC-Kern ARM® Cortex®-M0+, der mit einer Frequenz von 32 MHz arbeitt, eine Speicherschutzeinheit (MPU), embedded high-speed memory (192 KByte Flash program memory, 6 KByte data EEPROM and 20 KByte RAM) as well as a comprehensive range of extended I/As and peripheral devices.
