Self cleaning is especially useful in cases where sensor undergoes frequent power on/off cycles. In such scenarios it is recommended to turn self cleaning at least once per week in order to maintain reliable measurements. Self cleaning is activated by writing 1 to a dedicated attribute. Internal fan accelerates to its maximum speed and keeps spinning for about 10 seconds blowing out accumulated dust.
