I am interested in getting the PIR Motion Sensor for my son’s science project, but I’m confused about how you adjust/control its detection range and holding time.
At this wiki page, it shows the sensor module including two potentiometers for adjusting the detecting range and holding time: http://wiki.openpicus.com/index.php/GROVE_-_PIR_Motion_Sensor
But, the picture of the sensor on Dexter’s site, and on Amazon, does not show those potentiometers.
How does one adjust the detecting range and holding time without the potentiometers? Or, where can I get the version of the sensor module that includes the potentiometers?
