Acondicionamiento de señal de sensor infrarrojo

In the present work, the design and implementation of a device capable of monitor the cardiac pulse by means of photoelectric sensors was carried out, using the oximetry technique and in turn the photometry. Heart rate monitoring has great relevance in the field of health and technology, due to the large number of cardiovascular diseases and millions of deaths worldwide annually. There are currently several heart rate counters with limitations that cannot send your information via internet or GPRS, and cannot be filed on a computer. This prototype was made, based on a microcontroller that receives an infrared sensor signal, once properly conditioned It can be transmitted to a computer. The information obtained can be analyzed and stored by medical specialists, as well as transmitted by Wi-Fi to an application of a remote device providing a service with the use of technologies.
