OLG02
DiscontinuedOutdoor Dual Channels LoRa IoT Gateway
OLG02 is an open source dual channels LoRa Gateway. It lets you bridge LoRa wireless network to an IP network via WiFi, Ethernet, Or 3G/4G cellular via optional LTE module. The LoRa wireless allows users to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity. OLG02 has Rich Internet Connection method such as WiFi interface, Ethernet port and USB host port. These Interfaces provide flexible methods for users to connect their sensor networks to Internet. OLG02 can support customized LoRa transmit protocol. The design of OLG02 is use the Linux to directly control two sx1276/sx1278 LoRa modules which lets the LoRa can works in full duplex LoRa mode and increase the communication efficiency. OLG02 can be used to provide a low cost IoT wireless solution to support 50~300 sensor nodes. OLG02 can support mutiply working mode such as: LoRa repeater mode, MQTT mode, TCP/IP Client mode, TCP/IP Server mode to fit different requirement for IoT connection.

Application guide
Choose the airflow range by deployment scenario
0–10 m/s range
HVAC Ducts & AHU Verification
For HVAC supply or extract ducts, filter pressure-drop monitoring, and air handling unit performance checks.
0–30 m/s range
Industrial Ventilation & Fan Outlets
For main duct airflow, fan outlets, compressed air systems, and industrial ventilation monitoring.
How it works
Remote airflow monitoring via LoRaWAN
Deploy AirFlow-LN at critical airflow points, transmit measurements through a LoRaWAN gateway, and use platform data to detect weak airflow, filter problems, or abnormal ventilation conditions earlier.
- AirFlow-LN measures airflow in ducts, refrigeration, or ventilation points.
- LoRaWAN gateway receives data from distributed sensors across the site.
- Cloud platform visualizes trends and helps trigger maintenance decisions.
