Note:
1 This module does not have an NTC sensor. The NTC sensor needs to be purchased separately (10K/20K/50K/100K B3950 1%);The module’s measured resistance value is 1%, and the theoretical temperature range is -273s~200?FC. The final temperature measurement accuracy and temperature range are determined by NTC thermistor.
2 There are four different versions, be sure to use the corresponding sensor (10K/20K/50K/100K B3950 1%), otherwise the temperature will not be accurate
Package Include:
1?? Module Board
