Detect waving gesture at 1-2m

I am looking for a low cost sensor to detect hand waving at a distance of 1-2m.  I saw the SEN0626 Module detects 5 hand gestures.  can it be programmed to detect other gestures such as hand waving?  This is the right price level for what I am doing.  If not, is there another sensor that would detect hand waving at 1-2m?
