ODRDTR 气味探测器

smartclean 的描述

Our system works on dynamic thresholding instead of static thresholding to determine the tolerable limits for each unit. This approach takes into account that every toilet is unique in terms of its characteristics - its location, shape, size, ventilation, and seasonal variations, etc., and, hence, has a unique odour level.
