1. What is the difference between a temperature sensor and a thermistor?
There are significant differences between thermistors and temperature sensors in terms of technical principles, performance characteristics, and application scenarios.
Technical principles
Thermistor: The thermistor is a special type of resistor whose resistance value changes as the temperature changes. According to the characteristics of resistance value changing with temperature, thermistors can be divided into two types: positive temperature coefficient (PTC) and negative temperature coefficient (NTC). The resistance value of PTC thermistor increases as the temperature increases, while the resistance value of NTC thermistor decreases as the temperature increases.
Temperature sensor: A temperature sensor is usually an active semiconductor device that outputs a voltage or current value proportional to temperature. This type of sensor usually works based on the principle of thermoelectric effect, resistive effect or thermal induction, and has built-in signal conditioning circuit and temperature compensation function, which can provide accurate and linear temperature measurement over a wide temperature range.

2. What are NTC and PTC temperature sensors?
Both NTC and PTC temperature sensors are thermistors, and their main differences lie in the temperature coefficient and the change characteristics of resistance value with temperature.
Working principle and materials
NTC temperature sensor: Based on the temperature characteristics of semiconductor materials, its core material is usually one or more layers of ceramic materials, with the main components being metal oxides such as manganese, cobalt, nickel and copper. When the temperature increases, the electronic activity inside the conductive material increases, causing the resistance value to decrease, showing a negative temperature coefficient characteristic.
PTC temperature sensor: It is a thermistor whose core is a polymer material (such as polymer ceramic). When an electric current passes through it, the material generates heat, which increases the resistance. When the current decreases, the resistance value decreases. Therefore, by measuring the change in resistance value, the change in temperature can be calculated, showing a positive temperature coefficient characteristic. -
