The SN50V3-LB LoRaWAN sensor node is a long-range LoRa sensor node. It is designed for outdoor use and is powered by an 8500mA Li/SOCl2 battery for long-term use.SN50V3-LB is designed to help developers quickly deploy industrial-scale LoRa and IoT solutions. It helps users turn their idea into a practical application and make the Internet of Things a reality. It's easy to program, build and connect your things anywhere.
The SN50V3-LB is based on the SX1262 and allows the user to send data and achieve extremely long ranges at low data rates. It provides ultra-long range spread spectrum communication and high interference immunity with minimal power consumption, targeting professional wireless sensor network applications such as irrigation systems, smart meters, smart cities, smartphone detection, building automation, etc.
The SN50V3-LB features a high-performance 48Mhz ARM microcontroller with 256KB Flash and 64KB RAM. It has multiplex I/O pins for connecting to various sensors.
The SN50V3-LB has a built-in BLE module that allows the user to configure the sensor remotely via a mobile phone. It also supports OTA upgrades via private LoRa protocol for easy maintenance.
SN50V3-LB is the 3rd generation of Dragino's LSN50 series generic sensor node. It is an open source project and has a mature LoRaWAN stack and application software. The user can use the pre-installed software for their IoT projects or easily customize the software to suit different needs.Features: LoRaWAN 1.0.3 Class A SX1262 LoRa core Ultra-low power consumption Open-source Hardware/Software Bands: EU868 Supports Bluetooth v5. 1 and LoRaWAN remote configuration Supports wireless OTA update firmware Uplink at regular intervals Downlink to change configuration 8500mAh battery for long-term operation IP65 Waterproof External LoRa antenna Applications: Wireless alarm and security systems Home and building automation Automated meter reading Industrial monitoring and control Irrigation systems with long range, etc. Specifications: Micro Controller:MCU: 48Mhz ARM Flash: 256KB RAM: 64KB Common DC Characteristics: Supply voltage: 2.5v ~ 3.6v Operating temperature: -40 ~ 85°C LoRa Spec:Frequency range, Band 1 (HF): 862 ~ 1020 Mhz Max +22 dBm constant RF output vs. RX sensitivity: down to -139 dBm.
