hi i am trying to make a thing that turms on a fan when the temp is high enough. i have got the fan working, and can turn on and off the fan from the arduino which i am using for the project. the arduino can also read the thermistor's resistance, but it's not very consistante:
Analog reading 241.00
Thermistor resistance 3081.84
Analog reading 206.00
Thermistor resistance 2521.42
Analog reading 233.00
Thermistor resistance 2949.37
Analog reading 984.00
Thermistor resistance 252307.93 squeez thermistor
Analog reading 0.00

Analog reading 1023.00
Thermistor resistance inf
Analog reading 689.00
Thermistor resistance 20628.74
i got these patterns throughout the test, and i was wondering if i could make it more consitant, as i don't want the fan to keep turning on and off all of the time.
also could somebody tell me how to convert the restance to degrees fahrenheit
Thanks =)
