Capture Started Strings with %t and %u

Question

What modification can I make to capture humidity and temperature of my serial port to insert within a variable the humidity that is printed on the serial port as %u00.00 and the temperature %T00.00.

Usually with single characters, example 'O',I use part of the function below, now what I’m not getting is that this buffer only matches the values that start in %t or %u so that I store in a variable and print on my LCD.

void recebeir(){
char valorlido = Serial.read();
if (valorlido == 'O'){ //liga ou desliga a tv
{ 
for (int i = 0; i < 1; i++) //Envia um flash de led com 3 comandos
irsend.sendRaw(S_pwr,68,38); //código clonado
delay(52);
 }
 Serial.println("Liguei ou Desliguei a TV");
 }

Thank you!

I don’t know Arduino, but by your explanation and by the code you showed the logic could be more or less like this:

void recebeir()
{
   char temp[5], umid[5];

   char valorlido = Serial.read();

   if (valorlido == 'O')
   { //liga ou desliga a tv
      for (int i = 0; i < 1; i++) //Envia um flash de led com 3 comandos
          irsend.sendRaw(S_pwr,68,38); //código clonado
      delay(52);
      Serial.println("Liguei ou Desliguei a TV");
   }

   else if (valorlido == '%')
   {
      // leitura de 't' ou 'u'
      valorlido = Serial.read();
      if (valorlido == 't')
      {
          for (int i = 0; i < 5; i++)
              temp[i] = Serial.read();
          // temp agora tem a temperatura: nn.nn
      }
      else if (valorlido == 'u')
      {
          for (int i = 0; i < 5; i++)
              umid[i] = Serial.read();
          // umid agora tem a umidade: nn.nn
      }
      else
      {
         // nao e' 't' nem 'u'
         // ...
      }
   }
   else
   {
      // nao e' 'O' nem '%'
      // ...
   }
}
