Hi my name is Alen . i need to detect the human presence using the mmWave sensor dfrobot .
I had written a code for it . it is using io2 pin communication . in it there is mmWave.h file . Unfortunately , i cannot find it in the library of this sensor .
Can you help me to get it ?
Any link would be preferable .
Below is the screenshot of the error that i got when i ran on arduino ide .

Hello Alen,
The header file of the library you're using is "<radar.h>" not "<mmWave.h>"
However, I'll suggest installing and using the dfrobot library https://github.com/DFRobotdl/DFRobot_mmWave_Radar/archive/refs/heads/master.zip
