ESP webserver bmp-180

igorlab · 29 Июн 2016

народ, потихоньку разбираюсь с вебсерваком на есп12, делаю программу из разных кусков кода, что нахожу в нете, вот кусок который просто считывает температуру и давление и отправляет в терминал - работает хорошо,

Код:

#include <Wire.h>
#include <Adafruit_BMP085.h>
// Connect SCL to i2c clock - on '168/'328 Arduino Uno/Duemilanove/etc thats Analog 5
// Connect SDA to i2c data - on '168/'328 Arduino Uno/Duemilanove/etc thats Analog 4

Adafruit_BMP085 bmp;
void setup() {
  Serial.begin(9600);
  if (!bmp.begin()) {
    Serial.println("Could not find a valid BMP085 sensor, check wiring!");
    while (1) {}
  }
}
void loop() {
    Serial.print("Temperature = ");
    Serial.print(bmp.readTemperature());
    Serial.println(" *C");
    Serial.print("Pressure = ");
    Serial.print(bmp.readPressure());
    Serial.println(" Pa");
    // Calculate altitude assuming 'standard' barometric
    // pressure of 1013.25 millibar = 101325 Pascal
    Serial.print("Altitude = ");
    Serial.print(bmp.readAltitude());
    Serial.println(" meters");
    Serial.print("Pressure at sealevel (calculated) = ");
   //erial.print(bmp.readSealevelPressure());
    Serial.println(" Pa");
  // you can get a more precise measurement of altitude
  // if you know the current sea level pressure which will
  // vary with weather and such. If it is 1015 millibars
  // that is equal to 101500 Pascals.
    Serial.print("Real altitude = ");
    Serial.print(bmp.readAltitude(101500));
    Serial.println(" meters");
    Serial.println();
    delay(1000);
}

переделал его под вывод данных нв веб страничку, может кому пригодится
