Interfacing Thermistor with Arduino to Measure and Display Temperature …

18/12/2017· Thermistor is temperature sensitive resistor, whose resistance changes according to the temperature. There are two types of thermistor NTC (Negative Temperature Co-efficient) and PTC (Positive Temperature Co-efficient), we are using a NTC type thermistor. NTC thermistor is a resistor whose resistance decreases as rise in temperature while in PTC it will increase the resistance as rise …

Characteristics of Thermistor (Theory) : Solid State Physics Virtual ...

A thermistor is a temperature-sensing element composed of sintered semiconductor material and sometimes mixture of metallic oxides such as Mn, Ni, Co, Cu and Fe, which exhibits a large change in resistance proportional to a small change in temperature. Pure metals have positive temperature coefficient of resistance, alloys have nearly equal zero temperature coefficient of resistance and semi …

Temperature Measurement with a Thermistor and an Arduino

A thermistor indicates temperature by a change in electrical resistance. The analog input pins of the Arduino can only measure voltage, so the electrical resistance of a thermistor cannot be measured directly1. A simple technique for converting the (variable) resistance of the thermistor to a voltage is to use the thermistor in a voltage divider, as shown in the left side of Figure 1. The right side of Figure 1 …

Thermistor Characteristics, Thermistor Design And Applications

The main advantages of thermistors for temperature measurement are: Extremely high sensitivity. For example, a 2252 Ω thermistor has a sensitivity of-1-1-1. Very fast response to temperature changes. Relatively high resistance. Thermistors are available with base resistances (at 25°C) ranging from hundreds to millions of ohms. This high resistance diminishes the effect of lead wires that can cause …

What is a Thermistor

A thermistor is a thermally sensitive resistor that exhibits a precise and predictable change in resistance proportional to small changes in body temperature. How much its resistance will change is dependent upon its unique composition. Thermistors are part of a larger group of passive components. And unlike their active component counterparts ...
