To get accurate readings from thermistor you need to know exact Vcc your arduino get and have 0,1% or 0,01% 10k resistor.
Right now I don’t get proper reading using
640-10K-1% Termistor, NTC;10k ;THT;3977K;-40÷125°C;500mW, VISHAY NTCLE203E3103FB0
Of course this thermistor has its own characteristics, for exapmle:
-10C - 55 046 Ohm
0C - 32 554 Ohm
10C - 19 872 Ohm
25C - 10 000 Ohm
30C - 8059 Ohm
What exact thermistor should I use with Cayenne, to get proper temperature reading?
PS I think this could be written in docs and tutorial to this sensor.
