   @btashton 
   It works now!
   sorry but it was my mistake. I've forgotten to connect a wire between VDDIO 
and ~CS on my module.
   after connecting them like 
[this](https://twitter.com/ide_yuta/status/1389471735892779010?s=20) , it works 
well. 
   
   As you said, pull-up resistors are needed. Without those resistors, sensor 
doesn't work. With those resistors, sensor works!
