ARDUINO BASED DEVICE FOR MEASURING PULSE

Abstract

The purpose of this paper is to describe how it can be built and used a device meant to measure the pulse and oxygen saturation, taking into account the properties of electronic and optoelectronic elements and also the operating mode of the operational circuit LM324. The device is based on the use of an Arduino Mega 2560 board, a pulse sensor, an LCD display and a sound emitter. This type of devices are very much used in the biomedical field to assess the physiological parameters of the human body. The use of the Arduino board allows the equipment to be easily made by any person with knowledges in the biomedical field but not only. This type of devices will be very useful to understand the biomedical apparatus but also to develop other equipment more precise and accurate than the ones that are very expensive.
