Averaging in software is preferable for temperature measurement. If you shield a sensor from air currents you leave it far more sensitive to radiation errors and errors from conduction along the leads. These problems only increase if you try to place a brick on the sensor to average the response, you simply decrease the dependence on air temperature and increase radiation and conduction problems. cheers, Neville Michie
