CH201 long distance range

By francescoanzal… , 26 May 2021

Hello,

I want to use CH201 to detect presence in a room.

I'm using gprmt_v7 firmware and maximum range set to 5000mm. However, the highest range I get is 1700mm, even if the target is way farther.
When target is closer than 1500mm instead, I see reasonable measures.

Any suggestion for the configuration or thresholds to set? Is there any other possible cause for this behavior?

Thanks
