This parameter sets the ADC Range. I am using platformio platform with esp32 and max30102 to develop pulse oximetry and heart rate sensor. Required fields are marked *. Hi, Determines the intensity of both Red and IR Light. This website uses cookies to improve your experience. The circuit utilizes the MAX30102 heart-rate/SpO2 sensor with integrated red and IR LEDs. border-radius: 5px; /* 5px rounded corners */ The perfect values for each of these parameters vary for each different sensor mounting mechanism and application. El MAX30102 se pone sobre la piel, por ejemplo en el dedo o la muñeca. }, false); Often this value is indicated as SPO2. Moreover, we will use the Server Sent Event with ESP32 to update the Web interface. Though not medical grade, the MAX30102 sensor can give accurate spo2 readings for most applications. Both hearts are BPM pictures and in the code you’ll see them as this format: To make them you can follow Adafruit tutorial or continue here: First thing to do is to make a 2 colors picture (Black with White background is better) and don’t forget to scale it (my OLED is 128×32 px) some are (128×64) so you should stay at this limits. The mounting determines the sensor performance more than anything else. SpO2 is taken out from a table stored on the memory calculated with empirical formulas. This book, Advances in Edge Computing: Massive Parallel Processing and Applications, addresses these challenges in 11 chapters. }, false); Calculate HR / SpO2. var dataHR; It has an I2C interface so it is very easy to use. Making one change at a time and observing the raw Red and IR Values will get you closer to the right setting slowly. Now, my sensor is connected through I2C while my OLED runs through SPI. dataSPO2.setValue(0,1, e.data); Maxim has given out the algorithm and code to convert the values from this sensor to actual SPO2 and BPM values. source.addEventListener('message', function(e) { optionsHR = { All architectures so you should have the correct permissions to perform this operation apt-get update apt-get! SPO2 MAX30102 Blood Oxygen Concentration Sensor. The SPO2 is the blood oxygen level and the SPO2Valid=1 shows that the data are valid. This may be true for the MAX30105 device mounted on the Sparkfun board but does not seem to apply to the MAX30102 on the MH-ET-LIVE board. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics . ]); This sensor has several applications: As said before, this sensor has an I2C interface. For the project I took two different heart pictures, scale them and most important !! explains this process in detail. The default values in Sparkfun’s example are a very good starting point. Red/Infrared Modulation Ratio This document does not go into the details of the SpO2 calculation, instead, it discusses the key The step-down converter MAX1921 converts the 2V to 5.5V supply input and generates the 1.8V rail for the heart-rate sensor. There are several applications where we can apply this project and it can further developed. console.log("Events Connected"); With each beat, the display value is changed in the OLED screen. Combining cutting-edge technologies and techniques with existing approaches, this book equips you with the tools and knowledge needed to develop new energy-efficient and environmentally friendly RFID systems. Heart rate and SpO2 are calculated every 1 second while (1) //dumping the first 25 sets of samples in the memory and shift the last 75 sets of samples to the top Lower the brightness to conserve power in battery applications. var chartHR; /* Add some padding inside the card container */ )rawliteral", //indicator to show if the SPO2 calculation is valid, //indicator to show if the heart rate calculation is valid. source.addEventListener('error', function(e) { It is very difficult to get good readings by pressing and holding the sensor in between your fingers.
