Pasien Monitor (Suhu Tubuh, Bpm, SpO2) Server Thingspeak

Pasien Monitor (Suhu Tubuh, Bpm, SpO2) Server Thingspeak

          Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat mengukur suhu tubuh dan Bpm - SpO2 dengan menggunakan nodemcu esp8266, data yang didapat lalu dikirimkan ke server Thingspeak. untuk lebih jelasnya berikut adalah komponen dan programnya

a. Komponen

b. Program Arduino IDE

#include <Wire.h>
#include <ESP8266WiFi.h>
#include "ThingSpeak.h"
#include <LiquidCrystal_I2C.h>
#include <Adafruit_MLX90614.h>  
#include <MAX30100_PulseOximeter.h>
#define REPORTING_PERIOD_MS 5000
#include "MAX30100.h" //library sensor

LiquidCrystal_I2C lcd(0x27,16,2); //library lcd

MAX30100* pulseOxymeter;   //library

int spo;
float bpm;
Adafruit_MLX90614 mlx = Adafruit_MLX90614();

float TargetC;
int dataadc;
int suhunya;
int bpmku;
int counter;

PulseOximeter pox;

uint32_t tsLastReport = 0;
String hrData = "";
void onBeatDetected()
{

}

int pinreset = D6;

// ThingSpeak Settings
String apiKey = "QWERTY123456HJK7";
const char *ssid = "wifihpku";
const char *pass = "123456789";

const char* resource = "/update?api_key=";

void setup() {
Wire.begin();
mlx.begin();
Serial.begin(9600);
lcd.begin();
lcd.clear();
pinMode(pinreset,OUTPUT);
digitalWrite(pinreset,HIGH);

//setting ke online
  Serial.println("Connecting to ");
  Serial.println(ssid);

  while (WiFi.status() != WL_CONNECTED){\
    delay(200);
    Serial.println(".");
    }
  Serial.println("");
  Serial.println("WiFi connected");

 //Serial.print("Initializing pulse oximeter..");
    if (!pox.begin()) {
        //Serial.println("FAILED");
        for(;;);
    } else {
        //Serial.println("SUCCESS");
    }
    
pox.setIRLedCurrent(MAX30100_LED_CURR_11MA);
pox.setOnBeatDetectedCallback(onBeatDetected);
}

void loop(){
 
pox.update();
if (millis() - tsLastReport > REPORTING_PERIOD_MS) {

    bpm = pox.getHeartRate();
    spo = pox.getSpO2();

    lcd.setCursor(0,1);
    lcd.print("B/S:");
    lcd.print(pox.getHeartRate());
    lcd.print("/");
    lcd.print(pox.getSpO2());
    lcd.print("     ");
       
    tsLastReport = millis();
}

mlx.begin();
TargetC = mlx.readObjectTempC();
suhunya = TargetC;

lcd.setCursor(0,0);
lcd.print("T: ");
lcd.print(suhunya);
lcd.print(" C   ");

if((bpm > 75)&&(bpm < 110)&&(spo > 95)&&(spo < 100)&&(suhunya > 33)&&(suhunya < 40)){
   
if (client.connect(server,80))   //   "184.106.153.149" or api.thingspeak.com
                      {
                           
                             String postStr = apiKey;
                             postStr +="&field1=";
                             postStr += String(bpm);
                             postStr += "\r\n\r\n";

                             client.print(String("GET ") + resource + apiKey + "&field1=" + bpm + "&field2=" + spo + "&field3=" + suhunya + " HTTP/1.1\r\n" + "Host: " + server + "\r\n" + "Connection: close\r\n\r\n");
                                       
                             client.print("Host: api.thingspeak.com\n");
                             client.print("Connection: close\n");
                             client.print("X-THINGSPEAKAPIKEY: "+apiKey+"\n");
                             client.print("Content-Type: application/x-www-form-urlencoded\n");
                             client.print("Content-Length: ");
                             client.print(postStr.length());
                             client.print("\n\n");
                             client.print(postStr);
                         
                             Serial.println(". Send to Thingspeak.");
                        }
