thermocouple - Why is this MAX6675 temp. sensor so wrong ...

I recently bought this MAX6675 sensor with a K-type thermocouple, and I'm wondering what's wrong with it. I'm been testing it against a DS18B20 based sensor (metallic tip), and MAX6675 is giving me readings way off the mark. I tested it putting both sensors together against a hot plate and taking readings every 15 seconds. Plate start from room ...

MAX6675 Thermocouple Temperature Module w/ Probe ...

· Do take note of the fact that the probe end or stainless steel braided shield cannot be grounded or the sensor readings will be incorrect. We measured a typical current draw of the module at 500-700uA and the MAX6675 chip max spec is A common misconception is that the module draws up to 50mA. That spec comes from the max current the SO pin can deliver, so that high current …
