AQS01-L -- LoRaWAN CO2 Sensor

Document

The Dragino AQS01-L 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.

AQS01-L is powered by a ER18505 4000mAh battery. The battery can last more than 2 years and is easy to change.

AQS01-L supports BLE configure and wireless OTA update which make user easy to use.

AQS01-L supports CO2 Alarm and Temperature Alarm* features, users can get an alarm for instant notice.

AQS01-L 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.
