Wireless Data Acquisition System Using Bluetooth

Eliminating the physical cabled connection between a data acquisition system and the data processing unit brings flexibility and robustness to every system, especially when this system is located in an industrial environment. This paper investigates the possibility to build a small-sized, low-cost wireless data acquisition system with improved power saving capabilities. The aimed computational platform is the PDA (Personal Digital Assistant) while the chosen wireless communication standard is Bluetooth. Data acquisition, storage and communication are implemented in microcontroller architecture with integrated A/D converter and UART interface and an external non-volatile memory chip.
