RS485 WaterProof RS485/UART to LoRaWAN Converter Battery Powered
The Dragino RS485-LB/LS is a RS485 / UART to LoRaWAN Converter for Internet of Things solutions. User can connect RS485 or UART sensor to RS485-LB/LS converter, and configure RS485-LB/LS to periodically read sensor data and upload via LoRaWAN network to IoT server.
RS485-LB/LS can interface to RS485 sensor, 3.3v/5v UART sensor or interrupt sensor. RS485-LB/LS provides a 3.3v output and a 5v output to power external sensors. Both output voltages are controllable to minimize the total system power consumption.
RS485-LB/LS is IP67 waterproof and powered by 8500mAh Li-SOCI2 battery or solar powered + Li-ion battery it is designed for long term use for several years.
RS485-LB/LS runs standard LoRaWAN 1.0.3 in Class A. It can reach long transfer range and easy to integrate with LoRaWAN compatible gateway and IoT server.
For data uplink, RS485-LB/LS sends user-defined commands to RS485 devices and gets the return from the RS485 devices. RS485-LB/LS will process the returns data according to user-define rules to get the final payload and upload to LoRaWAN server.
For data downlink, RS485-LB/LS runs in LoRaWAN Class A. When there is downlink commands from the LoRaWAN server, RS485-LB/LS will forward the commands from the LoRaWAN server to RS485 devices.
RS485-LB/LS Supports BLE configuration and wireless OTA update, which make user easy to use.
Each RS485-LB/LS pre-load with a set of unique keys for LoRaWAN registration, register these keys to the LoRaWAN server and it will auto-connect after power on.
