INTRODUCTION
This project evolves on the two aspects of use of piezoelectricity Green energy with the help of nanogenerators As a sensor for the development of a
Vibration Detector and Bluetooth Heart Rate Monitor for Structural Health Monitoring (SHM)

Program for Vibration Detector
void setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600);}
// the loop routine runs over and over again forever:void loop() { // read the input on analog pin 0: int sensorValue = analogRead(A0); // print out the value you read: Serial.println(sensorValue); delay(10); // delay in between reads for stability}
Program for Bluetooth Heart Rate Monitor
int count=0;unsigned long standard=60000;void setup() { Serial.begin(9600); // initializationSerial.println("Press 1 to receive data or 0 to STOP...");}void loop() {while (standard-millis()>0){ if(analogRead(A0)>50) { count=count+1; while(analogRead(A0)>7) {} }}

if (Serial.available() > 0) { // if the data cameincomingByte = Serial.read(); // read byteif(incomingByte == '0') { Serial.println("Transmission Stopped. Press 1 to RECIEVE!"); // print message }if(incomingByte == '1') { Serial.println("Pulse rate is:"); Serial.println(count); } } }
