HiLetgo 3pcs MINI SR602 Motion Sensor Detector Module Pyroelectric Infrared Sensory Switch High Sensitivity for Arduino PI

HiLetgo 3pcs MINI SR602 Motion Sensor Detector Module Pyroelectric Infrared Sensory Switch High Sensitivity for Arduino PI

Q: 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).

Q: 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.

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

It stays high till motion stops.

Q: 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
