Abstract :
This article deals with the implementation of wireless data transfer in biomedical applications concretely in photoplethysmography. It deals with the application of a Bluetooth module for data transfer to computer where further signal processing can be performed. The work describes a use of microcontroller serving for data flow control, communication and analog signal digitalization using integrated analog to digital converter. The article involves also photoplethysmographic sensor and hardware design description.
