instructables.com/NTC-Vs-PTC-Main-Difference-and-Applications/Yapay zekadan makale özeti
- Basic Concepts
- Thermistors are temperature-controlled resistors used for monitoring and safety
- Thermistor resistance varies non-linearly with temperature
- Resistance change follows beta (β) constant formula
- NTC Characteristics
- NTC thermistors use ceramic/metal composites for temperature sensing
- Resistance decreases with heating and increases with cooling
- Offers miniature size, stability, and high accuracy
- PTC Characteristics
- PTC thermistors have positive temperature coefficient
- Resistance increases with heating but remains constant in cold
- Used as reusable fuses in electronic systems
- Project Implementation
- Circuit uses NTC 10K in voltage divider with Arduino
- Temperature displayed in Celsius and Fahrenheit
- LED indicators show high and normal temperatures
- Project sponsored by JLCPCB for PCB manufacturing
