RP1 is for adjusting the delay: “ON TIME”.
RP2 is for adjusting the sensitivity.
VCC => to +5V DC (max 5V).
OUT => to Digital pins of arduino . (if the sensor detect a moving object, this pin output gives a LOW (0V) or HIGH (5v) level signal.)
GND => to ground.
More documentation will be soon available on our site, by section “download”.
