I am using an esp-01S Wi-Fi module to send temperature and heartbeat information to the thingspeak app using the AT comand from the arduino my code runs well and it establishes a connection on the serial monitor but i am unable to view the data on the thingspeak app Here is my thingspeak command
void setup() {
lcd.begin(16, 2);
pinMode(blinkPin,OUTPUT); // pin that will blink to your heartbeat!
pinMode(fadePin,OUTPUT); // pin that will fade to your heartbeat!
Serial.begin(115200); // we agree to talk fast!
interruptSetup(); // sets up to read Pulse Sensor signal every 2mS
// IF YOU ARE POWERING The Pulse Sensor AT VOLTAGE LESS THAN THE BOARD VOLTAGE,
// UN-COMMENT THE NEXT LINE AND APPLY THAT VOLTAGE TO THE A-REF PIN
// analogReference(EXTERNAL);
lcd.clear();
lcd.setCursor(0,0);
lcd.print(" Patient Health");
lcd.setCursor(0,1);
lcd.print(" Monitoring ");
delay(4000);
lcd.clear();
lcd.setCursor(0,0);
lcd.print("Initializing....");
delay(5000);
lcd.clear();
lcd.setCursor(0,0);
lcd.print("Getting Data....");
ser.begin(9600);
ser.println("AT");
delay(1000);
ser.println("AT+GMR");
delay(1000);
ser.println("AT+CWMODE=3");
delay(1000);
ser.println("AT+RST");
delay(5000);
ser.println("AT+CIPMUX=1");
delay(1000);
String cmd="AT+CWJAP=\"Alexahome\",\"98765432\"";
ser.println(cmd);
delay(1000);
ser.println("AT+CIFSR");
delay(1000);
}
void esp_8266() {
// TCP connection AT+CIPSTART=4,"TCP","184.106.153.149",80
String cmd = "AT+CIPSTART=4,\"TCP\",\""; cmd += "184.106.153.149"; // api.thingspeak.com
cmd += "\",80";
ser.println(cmd);
Serial.println(cmd);
if(ser.find("Error")) {
Serial.println("AT+CIPSTART error");
return;
}
String getStr = "GET /update?api_key=";
getStr += apiKey;
getStr +="&field1=";
getStr +=String(temp);
getStr +="&field2=";
getStr +=String(pulse);
getStr += "\r\ end";
// send data
length cmd = "AT+CIPSEND=4,";
cmd += String(getStr.length());
ser.println(cmd);
Serial.println(cmd);
delay(1000);
ser.print(getStr);
Serial.println(getStr);
//thingspeak needs 15 sec delay between updates
delay(3000);
}
Also i tried using the examples on thingspeak to upload a value in the channel but the serial monitor kept showing Error
"wifi shield not present"

Please format your code.
Remove the currently posted version of the code here. Then, in the editor, click on the ">" button in the "CODE" toolstrip immediately above the editor entry window. That will create a code entry region. Paste the formatted code into there.

I recommend starting with the example here as a starting point for your code. The ThingSpeak library on Github is to help users get started and I would strongly recommend using that when possible.

I have tried the examples the serial monitor keeps indicating that the wifi shield is not present

I think that means you are using the wrong code. You can select the esp8266 via AT commands examples in the library.
