The detection distance in the datasheet is up to 3m to 5m. However, 2m is the best detection distance that we recommend, and 25℃ is the most suitable temperature.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-TIqOduxIYo16VexBlA3lJZEbgPf\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-TIqOduxIYo16VexBlA3lJZEbgPf\"\u003eThe sensitivity of the sensor is adjustable. There is a reserved pinout on the back of the board so that you can solder a slide rheostat to adjust the sensitivity. If you think that its sensitivity is not enough, dragging the plastic cap a little up will help enhance sensitivity.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-OhY8dEvAyoVidGxMV8zlFoTAg8g\"\u003e\n\u003cstrong\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-OhY8dEvAyoVidGxMV8zlFoTAg8g\"\u003e\n\u003cstrong\u003eNote: \u003c\/strong\u003ePlease note that orientation can influence its sensitivity.

When the sensor is inactive, the two slots will sense the same amount of IR. The ambient amount radiates from the outdoors, walls, or room, etc. When a human body or any animal passes by, it intercepts the first slot of the PIR sensor. This causes a positive differential change between the two bisects. But when the body leaves the sensing area, the sensor generates a negative differential change between the two bisects.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line
