DESIGN AND IMPLEMENTATION OF COMPUTER MICRO-CONTROLLER BASED HEART BEAT MONITOR
ABSTRACT The use of microcontroller is in every field even we can use it in the design and fabrication of biomedical equipments. A little example is here. The microcontroller at89s51 (8051) is here used to develop a heart beat monitoring system. By placing your finger in between a LED and photo resistance, we can detect the pulses of heart, the analog voltages are further processed with an operational amplifier LM ...
