USB modules are a very handy and reliable solution for data acquisition: They allow the I/O hardware to move close to the sensor. Thus only insusceptible digital data has to be transmitted to the PC. But there may be cases where you want to get rid of any cables. With the RedLabs WLS you can chose from transmitting data to a PC via USB or via wireless USB. Simply add the wireless USB receiver RedLab WLS-IFC to the PC. You will notice the difference only in the distance of your transmission: It can be up to 730 m for wireless!
