This paper presents the performances of a pletysmographic sensor used to measure pulse, integrated in a ZigBee wireless network. The sensor, based on a LED and a photo-transistor and the conditioning circuit and its parameters are presented. The integration in a ZigBee network using a development kit (PICDEM Z) concludes the paper.
This paper aims to investigate the performance of a system consisting of plethysmographic sensors used to measure the human pulse (or heart rate), and ZigBee wireless networks used to collect the data in view of processing and storing. A demo system build around a MICROCHIP development kit (PICDEM Z) is described. Some conclusion derived on the basis of the(More)
