Thermistor is usually a semiconductor sensor whose resistance varies with temperature. Its
common characteristic is resistance is quite sensitive to temperature, and can display
diverse resistance values at distinct temperatures.
Hence, the environmental temperature price of thermistor may be deduced reversibly according to the
shown resistance price.It's the advantages of significant sensitivity, modest quantity, little warmth capacity, fast reaction and very low cost.In accordance with the various
temperature coefficient, it can be divided into positive temperature coefficient
thermistor (PTC), destructive temperature coefficient thermistor (NTC) and critical
adverse temperature coefficient thermistor (CTR).The resistance worth of PTC
increases with the increase of temperature.The resistance value of NTC decreases
with the rise of temperature.CTR features a detrimental resistance mutation
attribute. At a particular temperature, the resistance worth decreases sharply with
the rise of temperature and has a large negative temperature
coefficient.Thermistors are used for various applications thanks to their different
properties.PTC is generally employed as heating element and overheating safety.NTC
is mostly utilized for temperature measurement and temperature compensation.CTR
is mostly utilized for temperature thermistor arduino Manage, alarm and various purposes.NTC
temperature in the variety of sixty ~ + three hundred ℃, the nominal price generally between 1
to a hundred m, the exact resistance and thermal resistor can expand linear array
