Temperatur-Messer

In diesem Projekt wird gezeigt, wie man mit Arduino Nano und OLED die Temperatur und Luftfeuchtigkeit messen kann.

Hier ist der Arduino Code:

int temp=0;

int hum=0;

void setup(){

i2c_oled_initall(i2coledssd);

Wire.begin();

Serial.begin(9600);

Serial.println(“Temperature misuration”);

Serial.println();

Serial.println(“Type,\tstatus,\tHumidity (%),\tTemperature (C)”);

}

void loop(){

char buffer[30];

char buffe [20];

disp_buffer_clear(COLOR_BLACK);

disp_print_xy_lcd(0, 0, (unsigned char*) “DEGREES”, COLOR_WHITE, 0);

disp_print_xy_lcd(0, 24, (unsigned char*) “HUMIDITY”, COLOR_WHITE, 0);

disp_lcd_frombuffer();

int stat;

Serial.print(“DHT11, \t”);

stat = DHT.read(DHT11_PIN);

switch (stat){

case DHTLIB_OK:

Serial.print(“OK,\t”);

break;

case DHTLIB_ERROR_CHECKSUM:

Serial.print(“Checksum error,\t”);

break;

case DHTLIB_ERROR_TIMEOUT:

Serial.print(“Time out error,\t”);

break;

default:

Serial.print(“Unknown error,\t”);

break;

}

// DISPLAT DATA

Serial.print(DHT.humidity,1);

Serial.print(“,\t”);

Serial.println(DHT.temperature,1);

temp = DHT.temperature ;

hum = DHT.humidity;

sprintf(buffer, “%4d Celsius”, temp);

sprintf(buffe, “%4d / 100”, hum);

disp_print_xy_lcd(0, 11 ,(unsigned char*)buffer, COLOR_WHITE, 0);

disp_print_xy_lcd(0, 35 ,(unsigned char*)buffe, COLOR_WHITE, 0);

disp_lcd_frombuffer();

delay(4000);

}
