V Thermistor application example Of The Epoxy Resin NTC Thermistor 100K 4200
Thermistors serve a crucial role in temperature detection. For example, thermistor temperature detection
can be used in fire alarms to detect fires based on a sudden change in temperature. Unlike photoelectric
detectors or ionization alarms, thermistors only require heat to activate.

Temperature measurement for home electronics (fire alarm)
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 doesn’t 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.
