STHS34PF80 configuration for 4 meters range

Hello community,

I have an application where I want to implement STHS34PF80 for detecting people PRESENCE and MOTION with a range of 3 to 4 meters. In the Datasheet it is stated that it is possible without using extra lenses. Although, I am struggling to find the best config to have a good recognition with more than 1,5m.

- What would be the step-by-step to make the sensor run in 4 meters range?

- Could someone give me an example config for THRESHOLD, HYSTERESIS, LPF, ODR and AVG?

Hi @Marcelo_GWA ,

For the configuration of the sensor and of the presence detection algorithm, we suggest to follow the procedure described in the AN5867.
