How to fine tune STHS34PF80 effective presence detection range ?

Hi All,

I started with example to make STHS34PF80 presence detection working.

Now I tried to add effective presence detection range.

Where should I start ? Is there a suggested process ?

My existing code is based on this example, however the presence detection range is around 1.2 meters.

I want to extend the range up to 2.5~3 meters however there is no criteria in example what parameters to tune.

Hi @SLin.11 ,

You can detect the presence at higher distance changing the threshold. Keep in mind that the sensor must be tuned based on the application and the environmental conditions.
