LM324 is an op-amp and thermocouple as a device generates voltage equivalent of the temperature. All you have to do is to amplify the voltage from thermocouple using opamp and interface it with the ADC of the microcontroller. Then you have to standardize it.
I dont know where you are getting stuck at, is it code, circuitary or what ?
