I use multiple HCSR-501 sensors around the fields and farm areas to detect wild animals.  They work great at night but give me many false signals during the day.  Each is sealed in a water proof enclosure. The whole system only is bad (HIGH errors when nothing is there) during the day.


Any ideas / suggestions to fix this?  Thank you.

Sunlight lots of IR, lots of talk about this, but no clear solution to the problem.

There are other Motion Sensors, ones that do not work on IR.

Perhaps this device will work better for you.  RCWL-0516

Or perhaps this one. WHDTS 2.25GHz Microwave Radar Detector Module
