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, Air pressure, and then upload to IoT server via LoRaWAN wireless protocol and shown in a 2.7" E-Ink Display.

CO2-LE is powered by a 2 x ER18505 4000mAh battery. The battery can last more than 2 years and is easy to change.

CO2-LE supports BLE configure and wireless OTA update which make user easy to use.

CO2-LE supports CO₂ Alarm and Temperature Alarm* features, users can get an alarm for instant notice.

CO2-LE supports Datalog feature, User can retrieve the sensor data from LoRaWAN commands.

Note*: CO₂ Alarm and temperature Alarm will decrease a lot the battery life.
