Simple One Wire Device
Startup Time: 2 Seconds to get a measure on room volume
Left Knob: Controls output latch delay (Between left-most 2 and right-most 300 seconds)
Right Knob: Controls center of best detection (Between left-most 3M and right-most 7M)
Out Pin: High means the environment has changed (intruder, dog, etc…) Low means it will keep checking.
