saya mau bertanya. Saya pakai wemos d1 mini untuk mengirim data ke web yang sudah saya buat. kalau ngirim localhost sudah bisa. tapi untuk mengirim ke host yang sudah saya punya kenapa ga bisa ya. pakai program yang sama tapi ip nya saya ganti. apa ada yang pernah mecobanya ? mohon bantuannya terimakasi
berikut program yang saya pakai untuk mengirim ke localhost
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
// Replace with your network details
const char* server = "172.20.10.3";
const char* ssid = "";
const char password = "";
const char SensorID= "ESP001";
const int sensorIn = A0;
int mVperAmp =80;
WiFiClient client;
double Voltage = 0;
double VRMS = 0;
double AmpsRMS = 0;
void setup() {
// Initializing serial port for debugging purposes
Serial.begin(115200);
delay(10);
// Connecting to WiFi network
WiFi.begin(ssid, password);
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.print(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println();
Serial.println("WiFi Connected");
}
void loop() {
Voltage = getVPP();
VRMS = ((Voltage/ 2.0) * 234375);
AmpsRMS = (VRMS / 4000000) * mVperAmp;
if (client.connect(server,80)){
Serial.print("Posting data");
Serial.print("Nilai Arus : ");
Serial.println(AmpsRMS);
client.println("GET /tes/index.php?AmpsRMS="+String(AmpsRMS)+"&&SensorID="+String(SensorID)+" HTTP/1.1");
client.println("HOST: 172.20.10.3");
client.println("Connection: close");
client.println();
while (client.connected()&&!client.connected()) delay(1);
while (client.connected() || client.available()){
char c = client.read();
Serial.print(c);
}
client.stop();
Serial.println();
}
delay(1000);
}
float getVPP()
{
float result;
int readValue; //value read from the sensor
int maxValue = 0; // store max value here
int minValue = 1024; // store min value here
uint32_t start_time = millis();
while((millis()-start_time) < 1000) //sample for 1 Sec
{
readValue = analogRead(sensorIn);
// see if you have a new maxValue
if (readValue > maxValue)
{
/record the maximum sensor value/
maxValue = readValue;
}
if (readValue < minValue)
{
/record the maximum sensor value/
minValue = readValue;
}
}
// Subtract min from max
result = ((maxValue - minValue) * 5.0)/1024.0;
return result;
}
