You need the poly Fresnel lens on the unit for it to work at distance . You should see a spike followed by a dip (20mV peak to peak) when a warm moving object is detected. See::www.makerguides.com/wp-content/uploads/2019/07/RE200B-Datasheet.pdf

Yes, I know about the lens but with it, the movement will be triggered even by standing to it unless there is something covering the sides and only the top is exposed. Thanks for the datasheet.
