Description

The RS485-LS is an RS485/ UART to LoRaWAN Converter for Internet of Things solutions. Users can connect RS485 or UART sensor to the RS485-LS converter, and configure RS485-LS to periodically read sensor data and upload via the LoRaWAN network to the IoT server.

RS485-LS can interface to the RS485 sensor, 3.3v/5v UART sensor, or interrupt sensor. RS485-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 a solar panel + 3000mAh li-on battery it is designed for long-term use for several years.

RS485-LS runs standard LoRaWAN 1.0.3 in Class A. It can reach a long transfer range and is easy to integrate with a compatible gateway and IoT server.

For data uplink, RS485-LS sends user-defined commands to RS485 devices and gets the return from the RS485 devices. RS485-LS will process these returned data according to user-defined rules to get the final payload and upload it to the LoRaWAN server.

For data downlink, RS485-LS runs in LoRaWAN Class A. When there are downlink commands from the LoRaWAN server, RS485-LS will forward the commands from the LoRaWAN server to RS485 devices.

RS485-LS Supports BLE configuration and wireless OTA update which makes users easy to use.

Each RS485-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 powering on.
