A/D Converter with Bluetooth Wireless Network in Data Acquisition

In some practice, the data sampling device is moving, so connect the sampling device to computer by ware is not convenience. This article has developed a Bluetooth-based wireless communications, mobile data acquisition and processing system to make up for general data acquisition. In particularly, a small light Bluetooth wireless A/D module as a collection of hardware is used. In this paper, the data collected is in real-time display and recorded, we develop a management system for data analysis and the data is very easy to future processing by various programming languages. Take the advantage of the function of two-direction communication that Bluetooth has, the system can set the A/D sampling rate and quantification bits in the microcomputer easily. It is a convenient and practical A / D acquisition system and you could achieve two-way signals and multi-channel signal acquisition.
