Hi everybody ;
I'm using a thermocouple type K to get temperature measurements, Given that the voltage is very low in thermocouple output, i'm using an AD595 to amplify it, and to display data i'm using an arduino UNO.
AD595 outputs an analogic signal (10mV/°C and 0°C=>10 mV) which received by the arduino analog pin, this last display it on serial monitor, the temperature value is obtained with the famous formula : temperature = (analog_reading*(5/1024))*100;
The problem is that i get incorrect values, the schema and the obtained data are in attached files
