DRAGINO · Sensor · LoRa · Air quality sensor (CO2) · AQS01-L-EU868

Overview

The Dragino AQS01-L is an indoor LoRaWAN air quality sensor for the Internet of Things solution. It is designed to measure environmental parameters including: CO2, temperature, relative humidity and air pressure, which are then uploaded to the IoT server via the wireless LoRaWAN protocol. AQS01-L is powered by an ER18505 4000mAh battery. The battery can last more than 2 years and is easy to replace.AQS01-L supports BLE configuration and wireless OTA updates, which makes it easier for users to use.AQS01-L supports CO2 alarm and temperature alarm* functions, so that users can receive an alarm immediately. AQS01-L supports the Datalog function, the user can retrieve the sensor data via LoRaWAN commands.

Note: CO2 alarm and temperature alarm significantly reduce battery life.
