Looking at the module i have with me, I cant tell it's a zener doide or it's another component. But if referring to the designator 'RT', it means thermistor, IF the manufacturer is following the common standard.

Referring to the User's Manual of the PIR sensor, the approximated detection range is 5 meter.
