1 This module does not have an NTC sensor. The NTC sensor needs to be purchased separately (B3950 10K 1%);The module’s measured resistance value is 1%, and the theoretical temperature range is -273-200°C. The final temperature measurement accuracy and temperature range are determined by NTC thermistor.
2 Be sure to use the correct sensor (B3950 10K 1% NTC), otherwise the temperature will not be accurate
