Hi ,
I wanted to askw hat do the human parameter data mean , like the heart rate , breath or what ? since at the library it doesnt specify them
and can i extract the number of people detected in some way ? like if there are 3 persons in that region at that specific time
thanks

Presence Status (S1 Output):

High Level: Indicates the area is occupied.
Low Level: Indicates the area is unoccupied.
Movement Status (S2 Output)
High Level Indicates active movement.
Low Level Indicates stationary presence.

These outputs allow the sensor to distinguish between an empty room, a room with stationary occupants, and a room with active movement.
The MR24HPC1 is primarily designed to detect human presence and movement within its range but does not natively support distinguishing or counting multiple individuals simultaneously.

Hi , thanks for your response.
Just to clarify , I was asking more specifically about this : void HumanStatic_func(bool bodysign =true) and int bodysign_val —— The value returned represents the value of the Human Movement Parameter. This value is only valid with the parameter bodysign=true.
Like I get some high values when I’m close to the sensor but I’m not sure what does it specifically mean

Hi there,

So I see this and from some testing and The Github info on it. For the first Question ,YES/NO you could calibrate the space by doing a couple things. I have found the best results depend on the environment space. As you see when you open the buffer and walk to it the returns from the radar doppler effect on the target (you) the data will increase pretty logarithmically btw,
Now if you characterize the room and Know some things you can parse through the data and get some basic stuff right away.

EMPTY room (no People, Pets or fans, AC OFF) take some samples and see if it settles to a consistent baseline number. Call that your ZERO.

Then add the other stuff and get some samples for different scenarios Collect the numbers.
As @liaifat85 indicated, with good data points you can tell if it’s occupied and by ONE or MORE* but I don’t think a count is possible unless you could isolate more info.
Read the Git for more specific data.

HTH
GL :slight_smile: PJ :v:

ps. even the particles in the space will effect the raw data when the buffer is open so sample more often and take less data in some cases. :+1:
