Dear All,

 

I get a question - can I connect DS sensors as shown on below picture with using USB?

Problem is that I get only 2 wires from sensor location to place where I can get UBS device.

If you only have 2 wires you can

wire 1 0v connected to pcb and pin 1 of the sensors

wire 2 connected to pcb TD and pin 2 of the sensors
