The faster the gesture, the closer together the peaks in the signals are. If the signal peaks are 
small (can be caused by the hand temperature being close to background temperature), it is 
recommended to reduce the sensitivity in the settings window as will be described later.   

5.2 

Gesture Trigger Threshold Option  

Setting the threshold for gestures to be lower will cause a greater chance of false gestures 
being registered caused by noise. And setting too high will make registering actual gestures 
less likely.  

5.3 

Gesture Detection Algorithm Peak Spread  

 

How far apart the peaks in signals can be before considered a gesture. The larger the 
value used, the more the system is affected by noise.  

 

Range:

 1 to 400  

 

Typical: 

12

  

PRESENCE DETECTION MODE 

A  presence  event  is  one  that  simply  states  that  an  object  of  higher  temperature  than  the 
background radiation has come into or moved out of the FoV of the sensor.
