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.
a solidstate sensor that detects the presence of an object by means of an electronic sensing field; doesn''t come into physical contact with the object
NTC thermistor can be assembled in housing in a variety of configurations for temperature sensing, measurement, detection, indicator, monitoring and control. Thermistor temperature sensor probe assemblies can conveniently attach to or be an integral part of any system to monitor or control temperature. The choice of assembly is dependent on the application.
· The most common methods use temperature sensors such as the thermistor, resistance temperature detector (RTD), thermocouple, or a silicon thermometer. However, selecting the right sensor is only part of the solution. That sensor must then be connected to a signal chain that maintains the integrity of that signal, while also accurately compensating for the unique characteristics of the ...

fabrication processes, thermistors can carry either a NTC or a PTC. As the temperature increases, NTC thermistors decrease their resistance value, while PTC thermistors increase their resistance value. As shown in Figure 1, it’s possible to further generalize Figure 1. Thermistor family overview. Temperature sensing with thermistors 3 February 2020 the resistance vs. temperature (RT ...
· Although the two sensors can be compared, when it comes to resistance value reading, PT 1000 thermistors show a reading by a factor of 10 compared to PT 100 sensors at the same temperature. Although the sensors are used interchangeably (depending on the instrument), there are certain instances where a PT 100 sensor is a better and more accurate option. PT 100 sensors are …
· This sensor can be used to compass functionality, which is accessible during the Navigation menu. Digital Sensors. Unlike analog sensor, Digital Sensor produce discrete values (0 and 1’s). Discrete values often called digital or binary signals in digital communication. Electronic sensors or electrochemical sensors in which data conversion and data transmission take place digitally are ...
· This sensor is called a thermistor. A thermistor exhibits resistance that is far more sensitive to temperature than that of other types of resistors. We will use an Arduino to measure and process the reading from a thermistor and then convert this into a humanfriendly format of common temperature units.
Thermistors are a type of semiconductor, meaning they have greater resistance than conducting materials, but lower resistance than insulating materials. The relationship between a thermistor’s temperature and its resistance is highly dependent upon the materials from which it’s made and is referred to as the temperature coefficient. It is composed of materials with known resistance and ...
It has two sensors on the module and each sensor contains two parts an IR emitting LED and an IR sensitive phototransistor. By measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or even objects directly in front of it. This module can be connected to the port with blue tags on Me Auriga.
The main function of this sensor is to monitor circuit temperature and generate an overheat signal in order to warn about excessive temperature of a circuit. So current is proportional to the absolute temperature, Iout is linearly related to temp. Depends on Ic or emitter area.
Of the basic sensor types, an NTC thermistor’s ability to achieve the highest accuracy is within the 50°C to 150°C range, and up to 250°C for glass encapsulated thermistors. Accuracy ranges from °C to °C. Stability. Stability is important in applications where longterm operation is the goal. Temperature sensors can drift over ...

The following NTC thermistor parameters can be found in the manufacturer''s data sheet. Resistance This is the thermistor resistance at the temperature specified by the manufacturer, often 25°C. Tolerance Indicates how much the resistance can vary from the specified value. Usually expressed in percent ( 1%, 10%, etc). For example, if the specified resistance at 25°C for a thermistor with ...
The of an NTC thermistor/NTC thermistor sensor assembly can be determined by first measuring the zeropower resistance of the NTC thermistor at two temperature points 10 °C to 25 °C apart. The thermistor is then placed in series with a variable voltage supply, a current meter, and a sufficiently large enough resistor to prevent too much current flowing through the circuit and allowing ...
