About NTC
The working principle of NTC thermistor is: when the temperature rises, the free electrons and holes in the thermosensitive material increase, causing the electron concentration within the material to increase, so the conductivity also increases. Since resistance and conductivity are related, resistance decreases as temperature increases.
The functions of NTC thermistor mainly include the following aspects:
1. Temperature measurement and control: NTC thermistors can be used to measure and control the temperature of various devices and systems, such as car engines, solar panels, refrigerators, ovens, etc.
2. Electronic circuit protection: NTC thermistors can be used for overcurrent, overvoltage, overheating and other protection of electronic circuits, such as power supplies, motor drivers, UPS and other equipment.
3. Environmental monitoring: NTC thermistors can be used to monitor indoor and outdoor environmental temperatures, such as greenhouses, weather stations, etc.
4. Medical equipment: NTC thermistors can be used in medical equipment, such as blood glucose meters, thermometers, etc.
5. Wearable devices: NTC thermistors can be used in wearable devices, such as smart bracelets, smart watches, etc., to measure physiological parameters such as human body temperature and heart rate.
