The Go Direct^® Air Quality Sensor (GDX-AIRQ) has a temperature channel as one of the many sensors included on it. This sensor is located inside the body of the particulate matter sensor. Due to electrical heat, it is possible for this temperature channel to report a reading that is slightly higher than what the actual ambient temperature is.

If the Go Direct Air Quality sensor is placed in direct sunlight, it is also possible this will cause excessive heating of the device. In this case the temperature channel may report a temperature reading that is significantly higher than ambient temperature. It is recommended to not place the Air Quality sensor in direct sunlight but in an indirect light or shaded location.

For a more accurate ambient temperature reading it is recommended to use the Go Direct^® Weather System (GDX-WTHR) or Go Direct^® Surface Temperature Sensor (GDX-ST).
