Where is the best place to place the logger and/or the external sensor?
A logger, or external sensor, best functions when placed in a location where abnormal air currents and environmental changes are not an issue. For example, if you want to monitor the temperature of a room, it is advisable not to place the logger too close to the door. Otherwise, every time the door is opened the logger and/or external sensor will be subjected to the temperature of the neighbouring room, while the, average, temperature of the room may not actually significantly change.
