Description

Es un oxímetro de pulso con un LED IR y un fototransistor, amplificado con dos LM358, ésta señal se digitaliza en señal cuadrada gracias a las compuertas NAND de un CI CD4093, para luego ser enviada a un PIC 16F84A el cual cuenta los pulsos durante 20 segundos y lo multiplica por 3 para mostrar en la LCD el resultado de los pulsos por minuto.
