NTC sensor specifications:
Product Name: 5*25mm NTC Waterproof Probe
Total length : 50CM
Resistance value: 10K
Resistance accuracy: ±1%
Resistance B value: 3950 ± 1%
Temperature range: -20 ° C -125 ° C
Wire size: 2651 26# parallel line temperature 105 °C

Note:
This module does not have an NTC sensor. The NTC sensor needs to be purchased separately (10K B3950 1%);The module's measured resistance value is 1%, and the theoretical temperature range is -273s~200°C. The final temperature measurement accuracy and temperature range are determined by NTC thermistor.
