8051 microcontroller Projects based Heart Rate Monitor HRM with SMS Alert
Heart Rate Monitor HRM with SMS Alert This project is 8051 microcontroller Projects based Heart Rate Monitor HRM with SMS Alert. Heart rate is sensed from the fingertip using a phototransistor / IR LED pair. This method is called photoplethysmography. Photoplethysmography is the volumetric assessment of an organ/tissue using light. IR reflection photoplethysmography is the … Read more
