I Description Of The Chip NTC Thermistor 0201
NTC thermistor is a ceramic semiconductor thermal crystal sintered from various metal oxides mainly manganese, cobalt and nickel. It is extremely sensitive to temperature changes. Its zero-power resistance varies with the body temperature. As the temperature increases, the resistance value decreases exponentially, and the temperature coefficient is as high as (3~6%/). A small temperature change will cause a large resistance value change. According to the R-T resistance temperature curve of the thermistor, the precise resistance value of each temperature point can be measured. In the circuit, the temperature can be digitally corresponded through the resistance value for temperature measurement and control.AMPFORT thermistors have low thermal time constants which result in extremely high rates of resistance change to accurately track the temperature.

VI Thermistor Temperature Detection in Fire Alarms
The thermistor method, unlike the previous examples, uses heat detection to activate. The alarm activates once the thermistor detects a high temperature. Thermistor temperature detection doesnot require smoke to activate and has fewer false alarms. The thermistor uses the ambient temperature of a building and will only activate when that temperature increases exponentially. The thermistor method is reliable in this fire alarm example as there would be few false alarms and a quicker alert rate, but the thermistor method is also versatile.

VIII Thermistor
Thermistors are a type of resistor that acts as a temperature-sensing element, generally made of ceramic or polymer. Thermistors exhibit a large change in resistance proportional to a small change in temperature.
Thermistors come in two common types:
NTC (Negative Temperature Coefficient) thermistors In these thermistors resistance decreases as temperature rises. An NTC is commonly used as a temperature sensor, or in series with a circuit as an inrush current limiter.
PTC (Positive Temperature Coefficient) thermistors â?? In these thermistors resistance increases as temperature rises. PTC thermistors are commonly installed in series with a circuit, and used to protect against overcurrent conditions, as resettable fuses.
