2.252K NTC Thermistor Human Body Temperature Sensor
A 2.252K NTC (Negative Temperature Coefficient) thermistor is a type of temperature sensor that exhibits a decrease in electrical resistance with an increase in temperature. The term "2.252K" refers to the nominal resistance value of the thermistor at a specific reference temperature, which is typically 25°C (77°F). For this particular thermistor, its resistance would be 2,252 ohms at 25°C.
NTC thermistors are commonly used in applications requiring precise and rapid temperature measurements, such as in medical devices for measuring human body temperature. They are popular due to their high sensitivity, fast response time, and relatively low cost.
When using a 2.252K NTC thermistor as a human body temperature sensor, it's important to note that the relationship between temperature and resistance is nonlinear. This means that to accurately measure temperature, the resistance value must be converted to temperature using a formula or a lookup table. The Steinhart-Hart equation is a widely used method for this conversion, but simpler formulas can also be applied depending on the required accuracy.
