Hello,
I am currently developing a presence detection system using the STHS34PF80 sensor. My goal is to detect a person at a distance of approximately 2.5 meters.
I am experiencing an issue regarding stationary subjects. While the sensor successfully detects a person entering the Field of View (FoV) at 2.5m, the TPRESENCE signal (read from TPRESENCE_L and TPRESENCE_H) gradually decreases over time if the person remains completely still. Eventually, the value falls below the threshold, and the sensor no longer reports "Presence."
Please refer to the attached graph below.
