From the manufacturer's datasheet for FTK+ LoRaWAN.
Overview
The FTK+ measures relative humidity and temperature in ventilation ducts and clean rooms, with humidity accurate to 2%. It reports over LoRaWAN at 868 MHz and also has two 0 to 10 V or 0 to 5 V outputs, so it can feed a local controller at the same time. Humidity outputs can be set to absolute humidity, enthalpy or dew point. In shielded locations an external antenna can be fitted to improve the link to the gateway. Air speed in the duct should not exceed 12 m/s.
