Dragino HE is a minimal system which installed with OpenWrt Linux system and support 150M 2.4G WiFi. It is compatible with 802.11b/g/n. HE has rich interface such as Ethernet, USB, UART and plenty of GPIOs. HE use small outline package, it is used widely in WiFi solutions. HÉ means “core” in Chinese. Intend of HÉ module is to be used as the core of the IoT, WiFi solution. HE is based on Open Source OpenWrt system. User is free to modify the software for their applications.
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.
