The Dragino LAQ4 is a LoRaWAN Air Quality Sensor for Internet of Things solution. It is designed to measure the surrounding environment parameters include: TVOC(Total Volatile Organic Compound), eCO2(equivalent CO2), temperature and relative air humidity, and then upload to IoT server via LoRaWAN wireless protocol.

IAQ (Indoor Air Quality) is very important factor for indoor activity and human life. VOC(Volatile Organic Compound) are emitted as gases from certain solids or liquids and they are the main source for poor indoor air quality. LAQ4 provides the trend for IAQ measurement and, like all other TVOC sensors, LAQ4 requires calibration for more accuracy measurement on TVOC and eCO2.

LAQ4 supports temperature and humidity alarm feature, user can get alarm for instant notice.

LAQ4 supports Datalog feature, User can retrieve the sensor data from LoRaWAN commands.

Each LAQ4 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to local LoRaWAN server and it will auto connect after activation.

Common DC Characteristics:

    Supply Voltage: built in 4000mAh Li-SOCI2 battery
    Operating Temperature: -40 ~ 85°C

TVOC Sensor:

    0ppb to 29206 ppb. Values outside this range are clipped
    Temperature and Humidity Compensation
