}
//--------------LOOP-----------------
void loop(){

{
String postStr = apiKey;
postStr += "&field1=";
postStr += String(h/1023*100);
postStr += "r\n";
client.print("POST /update HTTP/1.1\n");

Serial.println(h/1023*100);
Serial.println("Data Send to Thingspeak");
}
client.stop();
Serial.println("Waiting...");

// thingspeak needs minimum 15 sec delay between updates.
delay(1500);
