IOTSU® AQ09 Combo for LoRaWAN®

IOTSU® AQ09 Combo is a wireless indoor devicedesigned for measuring and recording of changes in air quality. Air quality is assessed as a combination of particulate matter, temperature, humidity, and the concentration of carbon dioxide (CO2) and volatile organic compounds (tVOC).

The device can be mounted on any surface within the monitored space. Installation of this maintenance-free device is quick and easy. Transmission and measurement cycles can be adjusted according to the

IOTSU® AQ09 Combo uses the global LoRaWAN® network connection. There is no need for external power supply. Depending on transmission settings and environmental factors the battery of the device can last 5 years.
