The heart beat with the varying blood pressure leads to a measurable change in the visual content of peripheral blood vessels. This is as good at the finger detect. There are two project work available, which were so far advanced that the optical signal pulse seized on a liquid crystal display graphically. Both works have been with a microcontroller PIC16C74 to collect and visualization of the signals.</p> <p><a href="http://www.uelectronics.info/measuring-heart-rate" target="_blank">read more</a></p> Microchip PIC LCD measurement PIC16C Sat, 21 Jun 2008 07:34:28 +0000 admin 208 at http://www.uelectronics.info
