Digital Blood Pressure Sensor with Serial Output For Arduino/Raspberry Pi -V3

This is digital Blood Pressure Sensor-V3 with serial output for Arduino Raspberry pi. Can be easily connected to Arduino  or Raspberry pi via serial communication**.     Program For Interfacing Blood Pressure sensor with Arduino. Connections: Sensor TX(Red Wire): Arduino RX Sensor RX(Orange Wire): Arduino TX ** Please make sure the supply never exceeds 5V. **

Please Watch the Tutorial video below on directions for interfacing reading blood pressure using Arduino.

Program:

void setup() 
{ 
Serial.begin(9600); 

} 
void loop() 
{ 
if(Serial.available()>0) 
{ Serial.println(Serial.readStringUntil('\n')); 
} 
} 

Output on Arduino IDE:

The code snippet for Arduino and LCD as shown in the video is can be seen below: If you are using LCD you require LCD I2C which can be purchased here.  Arduino can be purchased here.

#include<LiquidCrystal_I2C.h>
#include<SoftwareSerial.h>
LiquidCrystal_I2C lcd(0x27,16,2);

SoftwareSerial ss(9,8);
void setup() {

Serial.begin(9600);
ss.begin(9600);
lcd.init();
lcd.init();
lcd.backlight();
lcd.setCursor(0,0);
lcd.print(" BP Sensor V3");
lcd.setCursor(0,1);
lcd.print(" www.robosap.in");
delay(3000);
lcd.clear();

}

void loop() {

if(ss.available()>0)
{
lcd.clear();

String instr=ss.readStringUntil('\n');
if(instr.indexOf(',')>0)
{
int findex=instr.indexOf(',');

String bpdata = instr.substring(findex+1);

bpdata.trim();

lcd.print(bpdata);
delay(5000);

}
else
{

lcd.clear();
instr.trim();
lcd.print(instr);
delay(2000);

}
}
}
