This is the result from a run test (temps in °C): Basically, the greater the temp, the greater the difference between MAX6675 reading and "true" temp (as defined by DS18B20). In previous tests, when real temp reach 100°C, MAX6675 was giving ~150°C readings. This is not a offset or noise, but something else, almost exponential.

Basically, the greater the temp, the greater the difference between MAX6675 reading and "true" temp (as defined by DS18B20). In previous tests, when real temp reach 100°C, MAX6675 was giving ~150°C readings. This is not a offset or noise, but something else, almost exponential. What is wrong here?
thermocouple) With the MAX6675 chip and a Type K thermocouple you can easily measure temperature from from 0°C to 1024°C using any microcontroller since the chip outputs data via an SPI interface - here we are going to use it with the
MAX6675 continues to accurately sense the tempera- ture difference at the opposite end. The MAX6675 senses and corrects for the changes in the ambient temperature with cold-junction compen-sation. The device converts the ambient temperature reading into a voltage using a temperature-sensing diode. To make the actual thermocouple temperature
