If you need a different resistance value, you would still use this same process to select the right NTC thermistor temperature sensor. However, you would apply the required resistance value. Next up; we introduce you to theSteinhart-Hart modelof calculating the temperature coefficient using the re...

NTC热敏电阻是最常用的测温型热敏电阻,电阻阻值随温度按指数型变化(如图一)。它的非线性使得它在测量大范围的温度时准确率降低,最常用的测温区间是0-50。热敏电阻的电阻与温度的表达式[5]为:其中Rth(T)是温度为T时热敏电阻的阻值,B是热敏电阻的敏感度,R25是温度为25°C的电阻值。图四:NTC热阻的R-T曲线测温...
NTC thermistors are the most common, and that’s the type we’ll be using in this tutorial. NTC thermistors are made from a semiconducting material (such as a metal oxide or ceramic) that’s been heated and compressed to form a temperature sensitive conducting material. ...

Before you can control the temperature, you need to measure it. The most common method used in the RepRap community is to use a NTC thermistor. With the help of the circuit shown below, the AVR can measure a voltage, which depends on the used resistors and the temperature at the ...
- The 'standard' 2pin temperature sensors for motherboards and fan controllers are just simple 10k NTC thermistors? Seems overly complicated. When your circuit receives power, it means the computer is turned on. Why would you need to monitor the pwm signal from the motherboard?
