The WQ-pH and the WQ-DO sensors may be connected to the same computer, but they most likely will interfer with one another, causing misreadings. There are two solutions to this problem:

1. Connect the sensors to two separate computers for the data.

2. Use isolated USB Hubs to separate the two sensors’ grounds. Provided are two links to such USB Hubs.
