Arduino communication library for the HC-SR501 PIR (Motion) sensor
#Settings
Sensitivity - The detection range
Time - The output time for the L Detection Type
#Detection Types:
H - The sensor will continue to output HIGH signal as long as there is movement
L - The sensor will continue to output HIGH signal depending on the Time setting
#Notes:
- The delay time is stated to vary between 3 seconds and 5 minutes, but measuring shows that it is not true. There are signals, which length is around 1.5 seconds, when the knob is turned all the way to the start.
