What is the size of each module? (*NOT* the size of the package)

The circular circuit-board base is about 16 mm diameter x 1 mm thick. The connector plastic extends about 3 mm below the bottom of the base. The plastic dome housing the sensor is about 9.5 mm diameter x 10 mm high (height above circuit board).

What is the sensitivity with different sensitivity resistors? a table of delay time versus resistance is given. not sensitivity. comes with zero ohm.

It comes with zero ohm resistor seems being config for max sensitivity. Usually it is about 5-7m. I am not sure about this sensor since I didn't test. I asked for it I was not provided.

When there's continuous motion, does the output remain high or does it toggle low/high continuously?

It stays high till motion stops.

What is the volt. regulator on these things?? As far as i can tell, they don't actually exist except on these sensors!! A datasheet... something??!

Voltage supply range is 3.3V-15V (voltage input to the sensor), and voltage out/control from the sensor is 3.3V
