CO2-LE
LoRaWAN CO₂, Temperature, Humidity & Pressure Sensor
The Dragino CO2-LE is an Indoor LoRaWAN Air Quality Sensor for the Internet of Things solution. It is designed to measure the surrounding environment parameters include: CO2, Temperature , Relative Air Humidity and Air pressure, and then upload to IoT server via LoRaWAN wireless protocol. CO2-LE is powered by two ER18505 4000mAh battery. The battery can last more than 5 years and is easy to change. CO2-LE supports BLE configure and wireless OTA update which make user easy to use.

Application guide
Choose the airflow range by deployment scenario

Cold Storage & Display Cases
For supermarket chillers, refrigerated display cases, cold storage deadzone detection, VAV terminals, and clean rooms.

HVAC Ducts & AHU Verification
For HVAC supply or extract ducts, filter pressure-drop monitoring, and air handling unit performance checks.

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.
