What are thermistors NTC and PTC?
NTC and PTC are both thermistors, which are special resistors that can change resistance with temperature. They can also be said to be a kind of sensor.

Q: Can you explain sensitivity resolution in more detail? Why are higher values ​​better?
一個: High sensitivity eliminates any lead resistance. It also simplifies the supporting electronics. 一個 10,000 ohm thermistor changes resistance by 4.4% 或 440 ohms for a 1°C change in temperature. 一個 100 ohm platinum sensor changes resistance by 1/3 ohm for a 1°C change in temperature.
