Possible to do multiple if else/trigger statements on one arduino?

i think know answer this, figured i'd ask in case - can run multiple if else/trigger statements monitoring sensors on 1 arduino?

the first set of code monitoring temperature , turn on power outlet if temp drops level. second set of code monitoring moisture level of soil , turn on power outlet if moisture drops below level.

my guess need use 2 diff arduinos, 1 each code...

this note code way!

can combine code:

code: [select]

#include <u8glib.h>  // u8glib library
#include <dht.h>     // dht library

#define dht_apin a5  // analog pin sensor connected
dht dht;
int pinout = 8;
               /*uncomment , comment*/
u8glib_sh1106_128x64 u8g(13, 11, 10, 9, 8);  // din=13, clk=11, cs=10, dc=9, reset=8
//u8glib_ssd1306_128x32 u8g(13, 11, 10, 9, 8); // din=13, clk=11, cs=10, dc=9, reset=8
//u8glib_ssd1306_128x64 u8g(13, 11, 10, 9, 8); // din=13, clk=11, cs=10, dc=9, reset=8

void draw(void)
{
   u8g.setfont(u8g_font_fub17r);   // select font
   u8g.drawstr(0, 20, "temp: ");   // put string of display @ position x, y
   u8g.drawstr(0, 60, "hum: ");
   u8g.setprintpos(72, 20);        // set position
   u8g.print((dht.temperature * 9) / 5 + 32, 0);  // display temperature dht11 in fahrenheit
   u8g.println("f");
   u8g.setprintpos(60, 60);        // set position
   u8g.print(dht.humidity, 0);     // display humidity dht11
   u8g.println("%");
}
void setup(void)
{

}

void loop(void)
{
   dht.read11(dht_apin);  // read apin on dht11
   u8g.firstpage(); 
   do
{
   draw();
}  while( u8g.nextpage() );
  if (dht.temperature <= 70){
    digitalwrite(pinout, high);
  }
  else {
    digitalwrite(pinout, low);
  }
   delay(2000);  // delay of 2 sec before accessing dht11 (min - 2sec)
}


but have code running?

code: [select]

const int val_probe = 0; //analog pin 0
const int moisture_level = 250; // value after led goes on

void setup()
{
  serial.begin(9600);
  pinmode(13, output);
  pinmode(7, output);
}

void ledstate(int state)
{
  digitalwrite(13,state);
}

void loop()
{
  int moisture = analogread(val_probe);
 
  serial.print("moisture = ");
  serial.println(moisture);
 
  if(moisture > moisture_level)
  {
    ledstate(high);
    digitalwrite(7,high);
  }
  else
  {
    ledstate(low);
    digitalwrite(7,low);
  }
 
  delay(500);
}

if put 2 pieces of code should work. it'll run through code normal checking 1 after other. start @ top of loop , work way through; it'll @ 1 if/else tree , process of information , check conditions, , it'll go on next if/else tree , same thing.

one arduino can have infinite amount of if/else statements in it checking. long have enough input , output pins on arduino take in whatever data need , output whatever data need, should alright.
