Actually if you want a "smart sensor", I would look at Grid-Eye from Panasonic

Panasonics' infrared array sensor is a thermopile-type infrared sensor which detects quantity of infrared ray. These high precision sensors, based on advanced MEMS technology, have temperature detection, achieved on a two dimensional area, digital output, and have a miniature SMD package.
Check out Panasonic Grid-EYE Infra-Red Sensor Evaluation Kit | Farnell element14 It has the ability to detect the difference between human and a dog(animal).

If PIR is not an option, why don't you try a camera with your customized algorithms to detect multiple persons or give commands( to do such things)?
It would be more accurate and have great potential to do numerous things.
and the best part is you don't even have to interface it to computer to do such things, You can do that with several cheap developments kits available in market (Hint: RASPBERRYPI3-MODB-1GBRASPBERRYPI3-MODB-1GB and the camera(of course) : RPI CAMERA BOARDRPI CAMERA BOARD )
Good Luck
