Dragino AQS01-L is a LoRaWAN CO2 sensor

The Dragino AQS01-L is an indoor LoRaWAN air quality sensor designed for use in the Internet of Things. It is designed to measure environmental parameters including: CO2, temperature, relative humidity and atmospheric pressure, and then upload the data to an IoT server via the LoRaWAN wireless protocol.

The AQS01-L is powered by an ER18505 4000mAh battery. The battery can last more than 2 years and is easily replaced.

AQS01-L supports BLE configuration and wireless OTA update, making it easy to use.

The AQS01-L supports CO2 Alarm and Temperature Alarm* functions, allowing users to receive instant alerts.

The AQS01-L supports the Datalog function, which allows users to retrieve sensor data using LoRaWAN commands.

Note*: The CO2 Alarm and Temperature Alarm functions significantly reduce battery life.
