This paper presents the development of a wireless data acquisition system (WDAS) of incremental encoder sensors, for application in the real-time closed-loop control systems.The wireless technologies evaluated for the system were 433 MHz radio frequency (RF) and Bluetooth 2.0. The developed system was applied to the angular velocity control of a permanent magnet direct current (PMDC) motor, as a way of evaluating its development and also the time of communication with the different wireless technologies. The WDAS with the 433 MHz RF wireless module presented a satisfactory result, while the WDAS with the Bluetooth 2.0 wireless module was not adequate to this real-timeclosed-loop control system.
