Abstract
The application of high-speed real-time data acquisition is becoming increasingly wide spread in industrial field, and its measurement accuracy is also increasing. In the present study, the development of a USB based data acquisition system is presented here, where a microcontroller based standalone embedded system is used as data collection and also field control device. The data acquisition system has been calibrated in terms of output voltage generated in signal conditioner. The USB device system also calibrated for the error in the output result. Here USB device has been programmed as Human Interface Device (HID) class, hence not requiring any kind of device specific driver. This data acquisition system is utilized to measure the flow of a channel. The flow of water is not acidic.Keywords: USB, microcontroller, PIC, acquisition, data acquisition, programmer, digital
