Dear reader,
after update of the teensy 4.0 to ver 5.5. got only values of 3 db. (Via webinterface)
Updated the ESP to latest version from Helmut gitters Github page without sucess.
Never change a runninng system i know but i tried a new setup with SEN5x.
I choose the right microfon. Old setup with sps 30 and sht3X with same result.
Thanks in advance, André Loy
