Temperature sensor for my project

I would like to know a method to detect a human and animal separately by there temperature.

They are too close for common sensors.

interesting concept.

if you have a cold blooded animal, you man not detect it.

a dog generally runs hotter than a human, but humans wear their temperature on the outside surface, whereas the one wearing a fur coat would appear to be cooler.

a human couch potato will run cooler than a jogger as will a dog running and panting heavily vs one laying in the sun.

I would suspect that the normal temperature ranges are so overlapping as to make the data unuseable.

not sure how pet immune motion sensors work....

Maybe only look over 1 meter height? Would not work for children, though...

most motion sensors are IR, so detect heat, well rapid changes in heat within the envelope of the sensor.

if any and all motion below 1 meter were totally ignored, then it would seem to be a pretty simple matter to defeat a motion sensor. kids lying on skateboards would not be seen.
