A:To measure the cardiac pulse rate using Arduino, you can use a pulse sensor module that connects to the Arduino board. Here are the steps:
Connect the pulse sensor module to the Arduino board. Write a program to read the analog signal from the pulse sensor using the "analogRead" function in Arduino. Convert the analog signal to a digital signal using the "map" function in Arduino. Use a timer to measure the time between two consecutive peaks of the digital signal. Calculate the pulse rate by dividing the number of peaks by the time between two consecutive peaks and multiplying by 60 (since pulse rate is usually measured in beats per minute). Here's an example code to get you started:
scss Copy code int pulseSensor = A0; // Connect the pulse sensor to analog pin A0 int threshold = 550; // Set the threshold for detecting a pulse int pulseCount = 0; // Initialize the pulse count variable unsigned long lastBeatTime = 0; // Initialize the time of the last beat variable int pulseRate = 0; // Initialize the pulse rate variable
void setup() { Serial.begin(9600); // Initialize the serial communication }
void loop() { int sensorValue = analogRead(pulseSensor); // Read the analog signal from the pulse sensor if (sensorValue > threshold) { // If a pulse is detected if (millis() - lastBeatTime > 1000) { // If the time since the last beat is more than 1 second pulseCount++; // Increment the pulse count variable lastBeatTime = millis(); // Update the time of the last beat variable } } if (millis() - lastBeatTime > 2000 && pulseCount > 0) { // If the time since the last beat is more than 2 seconds and at least one pulse has been detected pulseRate = (pulseCount * 60) / ((millis() - lastBeatTime) / 1000); // Calculate the pulse rate Serial.println(pulseRate); // Print the pulse rate to the serial monitor pulseCount = 0; // Reset the pulse count variable } } Note that this is just an example code and you may need to adjust the threshold and timing parameters to get accurate results for your specific application. Also, please consult with a medical professional before using this or any other device for measuring your cardiac pulse rate.
